Static and Kinetic Friction

Lab Summary

Use a force sensor to investigate static friction and kinetic (sliding) friction.

Theory

This experiment investigates static friction and kinetic (sliding) friction. Students:

  • Compare static and kinetic friction for a system.
  • Calculate the static and kinetic coefficients of friction between two surfaces.

Method

Students gain experience by:

  • Measuring the static and kinetic forces of friction for an object sliding along a track.
  • Identifying the static and kinetic forces of friction on a Force versus Time graph.
  • Analyzing data collected in the lab to determine the static and kinetic coefficients of friction between two surfaces.
