Centripetal Force

Lab Summary

Use a force sensor to understand the factors that affect the centripetal force experienced by an object in uniform circular motion.

Theory

This experiment helps students understand the factors that affect the centripetal force experienced by an object in uniform circular motion. Students:

  • Isolate different variables to study the relationship between pairs of variables involved in circular motion.
  • Compare the force they measure to ideal calculations to help identify real world factors that affect experimental results.

Method

Students will gain experience conducting the following procedures:

  • Measuring the period of an object in uniform circular motion.
  • Changing one parameter at a time (mass, radius, and applied constant force) to determine its influence on an object in uniform circular motion.
  • Graphing parameters to determine the nature of their relationships.
