Circular Motion

An object that is moving at a constant speed as it moves in a circle has

• positive tangential acceleration

• negative tangential acceleration

• no tangential acceleration

• no centripetal acceleration

What affects the speed at which an object moves if it is traveling in a vertical circle?

• tension

• shape of the rod

• length of the string

• force of gravity
