(PS-2873C)

Features over 30 inquiry based labs covering the core topic areas of mechanics, electricity and magnetism, optics, thermodynamics and more.

Introduction to Force

Lab Summary

Use a force sensor to measure and experience contact forces, and some non-contact forces, in relation to gravity.

Theory

This lab introduces students to the concept of forces. Primarily, they will measure and experience contact forces, but there will be some inclusion of non-contact forces in relation to gravity. Through direct measurement and experience, students develop the foundations of understanding the vector nature of forces that will carry through to Newton’s laws and kinematics, and re-enforce their understanding of units of measure of force and mass.

Method

Students gain experience conducting the following procedures:

  • Measuring force using a data collection system.
  • Differentiating between units of mass and units of force.
  • Differentiating between contact forces and non-contact forces.
  • Creating free body diagrams of force.
