Centripetal ("center-seeking") force causes an object to move in a circle. Because of this, some animals move faster around the circle. Ride on a carousel and determine yourself whether it is the animals on the inside or the outside of the carousel move faster.
As the ride turns, is your body thrown slightly to the inside or outside?
Some of the animals also move up and down. Do you feel slightly lighter or heavier when your animal is going up ? What about when it is going down?
