Torque

Mr. Anderson explains torque in rotational motion, using examples like a wrench and a door. Torque is the product of force and lever arm, both perpendicular to the axis of rotation. He demonstrates how torque affects motion and balance, using a seesaw to illustrate balanced systems. The video concludes with a call to design experiments to explore these concepts further.

In a balanced system, what must be true about the torques on either side?

What happens to the torque when the lever arm is decreased?

How can you design an experiment to manipulate balanced forces using a teeter-totter?
