What is centripetal force?

Net constant force which causes an object to move in a circular path

4

What are the two facts about centripetal force?

It is always directed towards the center, an is always perpendicular to the velocity

5
New cards

What changes the direction in centripetal force?

Centripetal acceleration

Why does the speed of an object in circular motion not change?

The net force is directed perpendicular to the direction of motion, thus there is no work done and no change in speed
