Vectors and Projectiles

Vector Addition
Drag a vector onto the canvas. Drag the arrowhead to change its direction. Repeat up to two more times and guess the direction of the resultant. Click/tap a button and the resultant is drawn. Don't we all wish that adding vectors was that easy. With the Vector Guessing Game Interactive, a learner can improve their understanding and skill at adding vectors using the head-to-tail method.

Name that Vector
The Name That Vector Interactive is a skill building tool that presents users with 12 vector addition challenges. Twenty-five vectors are displayed on a grid; each challenge involves adding three of the vectors together to determine the resultant. The emphasis of the activity is on component addition. Built-in score-keeping makes this interactive a perfect candidate for a classroom activity.

Vector Guessing Game
The Vector Guessing Game will challenge learner's understanding of adding vectors.Two random vectors are displayed and learners must decide on the size and direction of the resultant. Be quick because the timer is counting down. The challenge is to solve as many correctly as possible in 20 seconds. Repeat the process and beat your high score. Challenge your friends; the loser has to do the winner's homework this evening. (Wait, scratch that last idea.)

Vector Addition: Does Order Matter?
The Vector Addition: Does Order Matter? Interactive is a short demonstration that focuses on a single question. Users investigate the question: does the order in which vectors are added together affect the magnitude or the direction of the resultant?

Projectile Simulator
The variable-rich environment of the Projectile Simulator Interactive allows a learner to explore a variety of questions associated with the trajectory of a projectile. Learners can modify the launch height, the launch angle, and the launch speed and observe the effect upon the trajectory. This Interactive can be used as a purely exploratory activity or be used with an activity sheet that guides learners to an understanding of several important principles associated with projectile motion.

The Monkey and the Zookeeper
Suppose that you are a zookeeper at a large zoo and that one of your primary duties is to feed the monkeys (just suppose). And suppose that one of the monkeys refuses to come down from the tree to receive the meal (you're still supposing aren't you). So what do you do? Of course, you build a banana cannon to shoot bananas to the monkey. But then you find out the monkey has the peculiar habit of letting go of the branch of the tree at the exact moment you launch a banana its way. So where should you aim the banana if you wish to direct it to the falling monkey. Should you aim at the branch, above the branch, or below the branch? And does the launch speed - fast, medium or slow - affect your decision? Let's find out with The Monkey and the Zookeeper Interactive.
