chp 10 circular motion flashcardizz review

Front

What is the net force on a car traveling in a circle with constant speed?

Back

The net force is directed toward the center of the curve.

Front

True or False: In a washing machine’s spin cycle, water is forced away from the clothes.

Back

False

Front

True or False: A bug on a turntable will make more turns per minute if it is located nearer to the center of the record.

Back

False

Front

What is a centrifugal force?

Back

A centrifugal force is often called fictitious because there is no mass pulling outward.

Front

True or False: The centrifugal force experienced in a rotational reference frame is a true force.

Back

False

Front

What is the direction of the net force acting on an object in circular motion?

Back

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

Front

Define centripetal force.

Back

Centripetal force is the net force that acts on an object moving in a circular path, directed toward the center of the circle.

Front

What happens to the speed of an object in circular motion if the radius of the circle decreases?

Back

The speed of the object increases if the angular momentum is conserved.

Front

What is the relationship between angular velocity and radius in circular motion?

Back

Angular velocity is inversely proportional to the radius for a constant linear speed.

Front

What is the formula for centripetal acceleration?

Back

Centripetal acceleration (a_c) = v^2 / r, where v is the linear speed and r is the radius.
