Learning objectives

Identify the pivot, force, and perpendicular lever arm.
Predict clockwise and counterclockwise torque.
Explain how force, distance, and angle affect torque.
Recognize torque in doors, wrenches, pedals, and screwdrivers.

Key concepts

Torque: a force multiplied by its perpendicular distance from the pivot.

Net torque: counterclockwise effects combined with clockwise effects.

Everyday torque: tools turn more easily when force acts farther from their pivot.

Suggested experiments

Keep force fixed and move the spring scale outward.
Keep distance fixed and change the force angle.
Compare the same force on a door handle, short wrench, and long wrench.
Place force directly at the pivot and observe zero torque.

Questions for exploration

Why are door handles placed far from hinges? Why does a longer wrench make a bolt easier to turn?
