Rotational Motion Activity

Front

What is the time required for one complete revolution called?

Back

Period

Front

Where is the best place to apply force to open a heavy door easily?

Back

At the edge of the door far from the hinges

Front

What direction does centripetal acceleration point in circular motion?

Back

Toward the center of the orbit

Front

What is the relationship between centripetal force and centripetal acceleration?

Back

Both point toward the center of the orbit and are in the same location.

Front

Which vector represents the acceleration of a ball in circular motion?

Back

Vector A

Front

What is centripetal force?

Back

The force that keeps an object moving in a circular path, directed toward the center of the circle.

Front

What is the formula for centripetal acceleration?

Back

a_c = v^2 / r, where v is the tangential speed and r is the radius.

Front

What is torque?

Back

A measure of the force that can cause an object to rotate about an axis.

Front

How does increasing the distance from the pivot point affect torque?

Back

Increasing the distance increases the torque for the same amount of force applied.

Front

What is the relationship between frequency and period?

Back

Frequency is the reciprocal of the period (f = 1/T).
