Objectives - Circular Motion

The Minds On Physics program consists of 15 modules. Each module covers a different topic and consists of a varying number of assignments. Every assignment addresses one or two objectives. The objectives for the Circular Motion module are listed below.

  • Assignment 1: Speed and Velocity
    • The student should be able to distinguish between the concepts of speed and velocity and use such concepts to describe the motion of objects in a circle.
    • The student should be able to identify and describe the direction of the velocity vector for an object moving in a circle and identify the variables effecting the magnitude of the velocity.
  • Assignment 2: Acceleration and Net Force
    • The student should be able to recognize that objects moving in circles have an acceleration and explain the cause of this acceleration.
    • The student should be able to describe the magnitude and direction of the acceleration and net force vector of an object moving in a circle at a constant speed.
  • Assignment 3: Centripetal Force and Inertia
    • The student should be able to use the concept of inertia to explain the reason that objects moving in circles have a tendency to move tangent to the circle.
  • Assignment 4: The Centripetal Force Requirement
    • The student should be able to use the centripetal force requirement to identify the force which act centripetally in order to cause an object to move in circular motion.
    • The student should be able to analyze a physical situation involving circular motion and compare the magnitude of the individual forces which act upon an object.
  • Assignment 5: Mathematical Analysis of Circular Motion
    • The student should be able to utilize Newton's laws to analyze the motion of an object moving in a horizontal circle and to determine the values of the acceleration, net force and individual forces.
    • The student should be able utilize Newton's laws to analyze the motion of an object moving in a vertical circle and to determine the values of the acceleration, net force and individual forces.
  • Assignment 6: Newton's Law of Universal Gravitation
    • The student should be able to recognize key elements of Newton's law of universal gravitation.
    • The student should be able to identify the variables effecting the force of gravity and predict the effect of alterations in these variables upon the force of gravity.
  • Assignment 7: The Acceleration of Gravity
    • The student should be able to define the acceleration of gravity and identify the variables which effect its value.
    • The student should be able to predict the effect of alterations in strategic variables upon the acceleration of gravity.
  • Assignment 8: Satellite Motion
    • The student should be able to identify the variables effecting the orbital speed of a satellite and discuss the dependence of orbital speed upon these variables.
    • The student should be able to identify the variables effecting the acceleration and net force acting upon an orbiting satellite and discuss the dependence of a and Fnet upon these variables.
  • Assignment 9: Weightlessness
    • The student should be able to distinguish between the weight of an object and the sensations of weightlessness experienced by an object and to explain the cause of these sensations.
    •  The student should be able to apply concepts of weight and weightlessness to explain a variety of motions such as roller coaster motions and satellite motion.
  • Assignment 10: Kepler's Laws of Planetary Motion
    • The student should be able to identify and describe each of Kepler's three laws of planetary motion.
    • The student should be able to use Kepler's law of harmonies to make calculations regarding the radius and period of orbits of planets.
