What's NEW at The Physics Classroom?

We've been at this task of providing students, teachers, and classrooms high-quality, ready-to-use resources for a long time. And we are as passionate about it now as we were 27 years ago when we started. We are always working on something new. But it is such a big website that the new additions often get nested deep inside of a section and are never noticed for months or even years after being published. So we're aiming to fix that problem with this page of announcements. Visit this page to find out about our most recent additions. And check back often in anticipation of finding new surprises.

Vertical Circle Simulation

Our newest Interactive is a simulation of the motion of an object in a vertical circle. The Interactive is filled with opportunities to explore the effect of one variable on another. There are four basic motions to study:
  • The motion of a ball on the end of a light string.
  • The moton of a ball on the end of a light, rigid rod.
  • The motion of a ball on the inside wall of a circular loop.
  • The motion of a ball that rolls down a ramp into a circular loop.
We will soon have a classroom-ready activity sheet for use with the simulation. Special thanks to Martin Kirby for making this generous contribution to our Interactives collection.
 


The Store

We have updated our Store in preparation for orders for the upcoming 2022-23 school year. We are adding two additional Task Tracker features - the Calculator Pad and Physics Interactives with Concept Checkers. Our Store now reflects those additions. And we have updated our price list to reflect the changes. This includes the offering of three bundled specials. And we have included a new Seat Calculator. Many other pages on the site have been changed to be consistent with the changes at the Store.

Physics Interactives - Balance It!

Version 2 of our Balance It! Interactive is now Task Tracker compatible. With 20 different levels, teachers may wish to take advantage of the ability to discard one or more of the levels. That will be a piece of cake with a Task Tracker account.
 


 

April 28, 2022

Slinky Wave Simulator Concept Checker

Concept Checker #52 is now out. If you've not tried one, perhaps its time to give one a test drive? The proposed idea is: 1) Have students do the simulation (use our activity sheet). 2) Process the activity. 3) Perhaps fit in a short lab, demonstration, or other follow-up activity. 4) Then close with the Concept Checker. 
 


Miscellaneous Edits:

It's never fun doing edits. But edits have to be done. Today's edits include:
 

April 27, 2022

Orbital Motion Concept Checker

We have released a Concept Checker to accompany our Orbital Motion simulation from the Physics Interactives section. The Concept Checker focuses on the magnitude and direction of the velocity and net force vectors for an elliptical orbit of a satellite.
 


Egg Drop Concept Checker - Revision

We have uploaded a Version 1.0.2 of our Egg Drop Concept Checker. This fixes an earlier bug that caused the Concept Checker to freeze when students answered the 13th question correctly. All is good now.
 

 

April 26, 2022

Young's Experiment Interactive

We just updated our Young's Experiment simulation to include Task Tracker code. Student progress is stored in the Task Tracker database for any student in an active subscription. Teachers can also shorten the assignment from three questions to one or two questions and set a miss penalty as a precaution against random guessing.
 



April 25, 2022

Who Can See Who? Concept Checker

The Who Can See Who? Interactive is a useful tool for helping students understand what objects can be seen in a mirror from a given vantage point. It does have the major drawback that students can guess and check their way through it as feedback is immediate and very specific. We now have a Concept Checker for this Interactive. With a large array of questions from which to select, there won't be a whole lot of guess-and-check-success with the Concept Checker.
 


Horizontal Circle Concept Checker

Our Horizontal Circle Simulator was added a couple of months ago. And now we have a Concept Checker to complement it. As of this addition, we now have 48 Concept Checkers for use with Physics Interactives.

 

 

April 23, 2022

Equivalent Resistance Interactive

The Equivalent Resistance Interactive is a 18-level game-like challenge found in the Electric Circuits section of our Physics Interactives. Students are given a set of resistors in series, parallel, or combination and must determine from a set of options which resistor values go with each resistor in order to provide a specified equivalent resistance. It is now Task Tracker compatible and offers all the features available to any Task Tracker user.
 

 

April 22, 2022

Go For The Gold Interactive

The Go For The Gold Interactive is a 16-level game-like challenge fround in the Forces in Two Dimensions section of our Physics Interactives. Students must add gold coins to a bag without breaking the rope. If the rope breaks they lose the coins. If they add the maximum number of coinswithout breaking the rope, they keep the coins and earn the star. Now the simulation is equipped with Task Tracker code to save student results in our database. It still works just the same as a Guest but the ability for instructors to both eliminate the more difficulty levels and be able to view student progress is a huge benefit.

 


April 20, 2022

Vector Addition Concept Checker

Our Vector Addition Concept Checker complements our Vector Addition Interactive. It includes 5 multi-part questions that emphasize the use of a component analysis to determine the magnitude and direction of a resultant formed by the addition of three angled vectors.

 

Stopping Distance Concept Checker

Our Stopping Distance simulation from the Work and Energy section of the Physics Interactives simulates the motion of a toy car rolling down an inclined track and striking a box at the bottom of the incline and skidding to a stop. The goal of the Interactive is to investigate the effect of the initial height upon the speed at the bottom and the distance the car (and box) skid to a stop. Now the simulation has a Concept Checker as a follow-up. 


 

April 19, 2022

Physics Interactives:  Chart That Motion

Our Chart That Motion Interactive in the Physics Interactives section provides a student engaging practice with the use of work-energy bar charts to describe the motion of an object. We have now equipped it with Task Tracker functionality and improved (we hope) the interface.



 

April 18, 2022

Physics Interactives:  Name That Image

Our Name That Image Interactive now has Task Tracker compatibility. It can be used as a Guest in the usual manner or it can be used as a logged-in Task Tracker student. Teachers with Task Tracker accounts will be able to assign this, customize it (throw out Questions), set partial scoring rules, and monitor student progress. Students will have their results saved at any point in their progression through the activity. Guest usage will remain exactly as it has been in the past with the added security advantage of answers being stored behind the firewall.


 

Physics Interactives:  Name That Vector

Our Name That Vector Interactive also has built-in Task Tracker compatibility. 



 

April 16, 2022

Physics Interactives:  Name That Charge

We have released Version 3 of our Name That Charge Interactive. The redo has furnished the Interactive with Task Tracker functionality, secured answers on the server, and improved some wording of questions. This is our fourth Interactive that we have incorporated Task Tracker code directly into the Interactive. This allows for teacher viewing of student progress and student ability to save their progress (among other advantages).


 

April 14, 2022

Physics Interactives:  Free-Body Diagrams

Our Free-Body Diagrams Interactive is immensely popular. But what has been missing is an ability to track students' progress.  And now that's no longer missing. We implemented some Task Tracker code to track the progress of students through a Task Tracker account. Students with Task Tracker accounts can now save their work and continue where they left off. All the old functionality has remained.


 

April 13, 2022

Physics Interactives:  Graph That Motion

Two of our most popular simulations are the Name That Motion and the Graph That Motion simulations. Each involve the task of observing an animation and matching it to either a verbal description or a graphical description. Our newest versions are now Task Tracker comptatible. This provides the simulation added security and the ability to use with (or even without) a Task Tracker account for the tracking and storage of student progress. Each has an updated set of animations that work well on all devices and in all browsers.


 

April 12, 2022

Physics Interactives:  Name That Motion

We have implemented some code within our Name That Motion simulation that makes it Task Tracker compatible. We also updated the animations to a different format for improved compatibility with more devices and browsers. The Task Tracker code will allow teachers to customize and assign the simulation with scoring rules for partial and complete progress. Student partial and completed progress records can be saved and retrieved.


 

Physics Interactives:  Task Tracker Compatibility

We added an announcement and a page of information about the use of Task Tracker with the Physics Interactives section. This feature will be available in the Fall of 2022. We are currently in the  beta-testing and development stage. You can always check out and use what we make at anytime. But during this beta-testing and development period, Task Tracker compatibility is only available to students who have a Minds On Physics Task Tracker account.


 

April 8, 2022

Filtering Away Concept Checker

During the school closures of the COVID 19 pandemic, we converted a classroom lab to an interactive simulation. It was called the Filtering Away simulation. Now we have a Concept Checker to go with it. Whether you do the hands-on lab (recommended) or the simulation (your best alternative if the equipment is not available), this 6-Question Concept Checker makes a great follow-up.


 

April 7, 2022

Charging Simulation - Student Exercise

Our Charging simulation in the Physics Interactives has lived for years without an accompanying classroom activity. That just changed. We have just published a classroom-ready student exercise for use with the Charging simulation. The activity focuses on the charging by induction process and the grounding process.


 

Charging Concept Checker

This 9-question Concept Checker coordinates with our Student Exercise (above) and accompanying simulation. Put the three of them together and you have a great lesson plan in the making.



 

April 6, 2022

Voltage Drop Analysis Concept Checker

Our DC Circuit Builder simulation is abnormally popular ... especially this time of the year. There are five classroom-ready exercises for use with the interactive. We just added a fourth Concept Checker to the collection that coordinates with the simulation and accompanying activities.


 

Skydiving Simulation - Student Exercise

Most of the simulations in our Physics Interactives section are accompanied by a classroom-ready exercise that can be used by teachers who are incorporating the simulation into a lesson plan. We have prepared the student activity for our Skydiving simulation.

 

Skydiving Concept Checker

Now that there is  student exercise to accompany the Skydiving simulation, why not have a Concept Checker? Done. Check out this 5-question Concept Checker that gets right to the point of the simulation.

Exercise 2: Refraction, Reflection, and Total Internal Reflection

Exercise 3: Total Internal Reflection


 

Refraction Concept Checker

And here's one more reason to use the Refraction simulation. This 6-question Concept Checker will provide refinforcement on the manner in which light bends at the boundary.


 

April 3, 2022

Wave Addition Concept Checker

Our 28th Concept Checker is now complete. If you've not tried pairing a Concept Checker with a simulation from our Physics Interactives section, perhaps you need to give one a try. They're free and you don't need an account to use them (though an account would improve the experience). Make the pairing part of one of your upcoming lesson plans.


 

April 2, 2022

River Boat Simulator Concept Checker

This 8-Question Concept Checker provides students a great check-up on understanding the interdependence between variables for a boat crossing a river.

 

Wave Addition Simulation

This is an awesome simulation that's been on our website for a couple of years but the widget needed a change in aspect ratio. We think we have found the perfect aspect ratio and the sim now displays nicely. Enjoy!

 
 

April 1, 2022

Painting With CMY Concept Checker

Those who are teaching or learning the physics of color addition and subtraction will enjoy our newest Concept Checker on Painting With CMY. Use the simulation to learn about the mixing of color pigments and use the Concept Checker as a check of your understanding.

 

A Few Edits

Mistakes happen. And when we find out about it we make an effort to upload fixes. Mission EC8 of our Minds On Physics program was revised to fix an interface issue. And our Thermal Stoichiometry Concept Builder was updated to fix two answer key errors.

Stage Lighting Concept Checker

We think some of our Light and Color simulations are the best among the group. And now the Stage Lighting simulation has a companion Concept Checker. For teachers and classrooms, the suggested use is:  (1) Do the simulation with the help of the accompanying classroom exercise. (2) Process the activity with the class. (3) Assign the Concept Checker as a follow-up ... either immediately or soon thereafter.
 

 

March 30, 2022

Fish Catch Concept Checker

The Fish Catch simulation is a good example of a simulation that was waiting for some next-step tool to solidify the learning. That wait is over. We now have a Concept Checker for it. Combining the simulation with the classroom exercise and following it up with the Concept Checker makes for a great lesson plan that blends physics and proportional reasoning skills. 
 


Exploding Carts Concept Checker

Like our Fish Catch simulation, the Exploding Carts simulation was in need of a companion tool to check on understanding. Inspired by the accompanying classroom activity, the questions in this Concept Checker will have students thinking in terms of ratios to predict the post-explosion velocity of a cart from knowlege of their masses.

Work-Kinetic Energy Interactive: Activity 2

We have completed a second classroom activity for the Interactive added yesterday. This activity is more in-depth than the first and takes a guided inquiry approach to the relationship between work and kinetic energy.



 

March 3, 2022

Work-Kinetic Energy Interactive

We have been on a simulation streak as of late. Simulations admittedly take more time to produce. But the products are well worth the time spent. This one on the topic of work and kinetic energy is filled with variables to manipulate and representations to view. There will be two classroom-ready activities for using the simulation with a Physics class. The first is available. We are still working on the second.

The Barrel Ride Simulator

Walk through the door and enter the barrel. The door latches shut, the motor revs up, the barrel starts spinning, the floor is pulled from out from under the riders, and the riders scream. For some, it's more fun to watch the ride than to ride it. But now you get to design it. Modify the parameters that influence the thrill and safety of the ride. And best of all, nobody is going to file a lawsuit if you get a bit too ambitious. Have some phun!




 

Febuary 23, 2022

Horizontal Circle Simulation

Our newest Interactive is a simulation of the motion of an object (actually three objects) in a horizontal circle. The Interactive is filled with opportunities to explore the effect of one variable on another. There are mulitple displays or representations and the animation can be viewed from multiple angles. We have provided a classroom-ready activity sheet for use with the simulation. Special thanks to Martin Kirby for making this generous contribution to our Interactives collection.
