Rotational Motion AP Physics

Angular Momentum is the product of...

• rotational inertia and linear velocity.

• linear inertia and angular velocity.

• linear momentum and angular velocity

• rotational inertia and angular velocity.

What does Rotational Inertia depend on?

• Mass

• Mass Distribution

• Both Mass and its Distribution

• Neither Mass nor its distribution

Centripetal acceleration is directed

• directed away from the center of the circle

• directed towards the center of the circle

• it is perpendicular to the radius at that point

• It has no direction

When a car goes around a circular curve on a horizontal road at constant speed, what force causes it to follow the circular path?

• the normal force from the road

• gravity

• the friction force from the road

• No force causes the car to do this because the car is traveling at constant speed and therefore has no acceleration.
