2 cards from this section. Quick, good the night before a test.
What is angular acceleration?
Think about how velocity changes in straight-line motion.
Write the formula for torque.
Recall how lever arms influence rotational motion.
What unit is used to measure angular acceleration?
Think about the relationship between angle and time.
True or False: Torque can cause an object to rotate.
Consider how force applied at a distance from the pivot affects rotation.
A solid disk of radius 0.5 m and mass 10 kg is rotating about its center. What is its moment of inertia?
Refer to the moment of inertia formula for disks.
A flywheel of mass 5 kg and radius 0.1 m experiences a torque of 2 N.m. Calculate the resulting angular acceleration.
Follow the steps for torque and angular acceleration.
