A car is moving in a circular path. At a certain instant, it has zero tangential acceleration and a non-zero centripetal acceleration. What is the car doing at that instant?

A car is traveling along a highway at 65 mph. Which point in the tires is moving forward at 65 mph?

A car is traveling along a highway at 65 mph. What is the linear speed of the top of the tires? What is the linear speed at the bottom of the tires?

A hollow cylinder and a solid cylinder are constructed so they have the same mass and radius. Which cylinder has the larger moment of inertia?

The preferred positive direction for angular displacement is the clockwise direction.

When a rigid body rotates about a fixed axis all the points in the body have the same angular displacement.

When a rigid body rotates about a fixed axis all the points in the body have the same linear displacement.

When a rigid body rotates about a fixed axis all the points in the body have the same angular speed.

When a rigid body rotates about a fixed axis all the points in the body have the same tangential speed.

When a rigid body rotates about a fixed axis all the points in the body have the same angular acceleration.

When a rigid body rotates about a fixed axis all the points in the body have the same tangential acceleration.

When a rigid body rotates about a fixed axis all the points in the body have the same centripetal acceleration.

Mass can be considered concentrated at the center of mass for rotational motion.

Rolling without slipping depends on static friction between the rolling object and the ground.
