2 cards from this section. Quick, good the night before a test.
What is the formula for calculating the moment of force (torque)?
Remember that torque depends on force and distance from the pivot.
What does the moment of inertia depend on?
Think about how mass is spread out or concentrated.
What is the formula for calculating torque?
Think about how far the force is applied from the pivot.
True or False: A larger moment of inertia means less resistance to angular motion.
Remember that moment of inertia measures resistance to rotation.
A figure skater pulls in her arms to spin faster. How does this relate to the moment of inertia?
Consider how distribution of mass affects rotational speed.
A gymnast completes a twist by rotating their moment of inertia. Explain how they control their rotation.
Think about how changing body shapes impacts spinning and control.
