# Physics: Balancing Torques and Forces

by Texas Instruments - Data Collection with Probes Lesson

#### Objectives

• Students will predict and describe the effect of balanced forces on an object.
• Students will measure or calculate the net force on an object.
• Students will describe the relationship between torque, force, and lever arm.

#### Vocabulary

• effort arm
• first-class lever
• fulcrum
• resistance arm
• second-class lever
• static equilibrium
• third-class lever
• torque

In this activity, students explore the conditions necessary to produce static equilibrium using first-, second-, and third-class levers.
As a result, students will:

• Change the length of the effort arm for each lever and measure the force necessary to achieve static equilibrium.
• Use these data to determine the relationships between torque, force, and effort arm for the different levers.
