Circular Motion

Lab Summary

Use a force sensor to develop a kinesthetic understanding of circular motion by measuring the period of rotation of a mass in uniform circular motion.

Theory

The majority of the experiences your students will have in mechanics center around linear systems. This experiment helps students make the transition from a linear frame of reference to a circular frame of reference. Students:

  • Develop a kinesthetic understanding of circular motion.
  • Apply Newton's laws of motion to an object undergoing uniform circular motion.

Method

Students gain experience conducting the following procedures:

  • Measuring the period of rotation of a mass in uniform circular motion.
  • Calculating the instantaneous velocity of an object in uniform circular motion.
  • Calculating the acceleration of an object in uniform circular motion.
  • Comparing force and acceleration values in uniform circular motion.
