The official tosses the ball up for the opening tip-off.

A player passes the ball to another player.

The basketball bounces off the backboard.

A player spins a basketball on his finger.

A police officer draws a sketch of the scene of an accident, as shown.

How does an object’s motion change as a result of centripetal acceleration?

The speed decreases in the same direction.

The speed increases in the same direction.

The direction changes along with the speed.

The direction changes but not the speed.

Two objects have the same center point of the circle, but are located at different positions away from the center point. Each object is moving with uniform circular motion.Which would describe the tangential speed of the objects?

both objects would have the same tangential speed

the object with the smaller radius has a faster tangential speed

the object with the larger radius has a faster tangential speed

both objects would have oscillating tangential speeds

Juan and Kuri are on a carousel. Juan is closer to the center of the carousel than Kuri. Which statement describes their tangential speeds?

Juan and Kuri move the same distance in one revolution, but Juan completes the revolution in less time and has a higher speed.

Juan and Kuri complete one revolution in the same time, but Juan travels a shorter distance and has a lower speed.

Juan moves a shorter distance in less time than Kuri, but their speeds are the same.

Juan and Kuri complete one revolution in the same time, so they have the same speed.

Which is a characteristic of centripetal acceleration?

It is directed outward from the center of a circle.

It is directed inward, toward the center of a circle.

It results in an object moving faster.

It results in an object moving slower.

0.30 m/s

1.2 m/s

1.5 m/s

7.5 m/s
