Physics: Balancing Act (HS)

by Texas Instruments - Simulation Lesson

Objectives

  • Students will describe a lever and fulcrum.
  • Students will define force vectors and torque.
  • Students will solve proportions for balancing different weights on a teeter-totter balance.

Vocabulary

  • acceleration
  • mass
  • force
  • Newton
  • fulcrum
  • simple machine
  • gravity
  • torque
  • lever

About the Lesson

Adapted from a PhETTM simulation, this lesson is a simulation of a teeter-totter where people and objects of different masses are placed at either end to test for balance.  This provides and opportunity to explore a lever and fulcrum simple machine, as well as to measure torque

As a result students will:

  • Describe a lever and fulcrum
  • Define weight as a force, as well as the unit of measurements for force.
  • Measure torque and solve equations involving torque.
