Circular Motion 1

The velocity is always _____ to the line of a circle. 

• outwards
• towards the center
• tangent
• faster

Which statement is true about an object that is traveling in uniform circular motion?

• The speed of the object varies.
• The net force on the object is directed toward the center of the circular path.
• The direction of the object's velocity is constant.
• The net force on the object is directed away from the center of the circular path.

Centripetal acceleration always points

• in the direction of the object's motion
• in the opposite direction of the object's motion
• towards the center of the circle
• towards the outside of the circle
