UCM

Tangential velocity is ______ to the centripetal force.

• parallel

• perpendicular

UCM is demonstrated by an object moving at a circular path at a constant _________.

Centripetal acceleration and radius has an ___________ relationship with one another.

• DIRECT

• INVERSE

__________ velocity is measured at any point tangent to a turning wheel.

________________ velocity if the rate of change of angular position of a rotating body.

Solve: If it took the object 6.42 s to complete one revolution, what is the tangential velocity of an object at a circular path whose radius is 0.34 m?

Solve: What is the tangential velocity of a stone whirling at a rate of 2.60 m/s2 if it is 0.60 m away from the center of the circular path?

This is the force that keeps the object moving at a circular path.

True or False: gravitational force may act as centripetal force.

• TRUE

• FALSE
