Circular Motion Review - 3A

Front

What is the net force direction when an object is at the top of a circular loop?

Back

Towards the center of the circle.

Front

What does the acceleration of an object in circular motion represent?

Back

The change in velocity direction as the object moves along the circular path.

Front

What do red arrows in a circular motion diagram typically represent?

Back

The velocity vector.

Front

What is true about an object in uniform circular motion?

Back

The net force on the object is directed toward the center of the circular path.

Front

What is tangential speed in circular motion?

Back

The speed of an object moving along the circular path, measured at any point along the path.

Front

What is centripetal force?

Back

The net force that acts on an object moving in a circular path, directed towards the center of the circle.

Front

How does the speed of an object in uniform circular motion change?

Back

The speed remains constant, but the direction of the velocity changes.

Front

What is the relationship between centripetal acceleration and radius?

Back

Centripetal acceleration is inversely proportional to the radius of the circular path.

Front

What happens to the net force if the speed of an object in circular motion increases?

Back

The net force must increase to maintain circular motion.

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.
