True or False: Centripetal acceleration causes circular motion.

• True
• False

What object experiences uniform circular motion?

• A car speeding up as it turns left
• A car traveling around a roundabout at a constant speed
• A car slowing down as it crests a tall hill
• A car traveling down the road at a constant speed

Why do objects experience centripetal acceleration?

• Because they are speeding up as they move in a circle
• Because they are constantly changing direction and the net change is directed inward
• Because they are constantly changing both speed and direction
• Because when you have 100 people pedaling, you can speed up more easily.
