Uniform Circular Motion is defined as the ______.

• Motion of an object in a straight line at constant speed

• Motion of an object in a circular path at constant speed

• Motion of an object in a circular path at varying speed

• Motion of an object in a straight line at varying speed

Centripetal Force is defined as:

• The force that acts on an object moving in a circular path and is directed towards the center around which the object is moving.

• The force that opposes the motion of two surfaces sliding past each other.

• The force that is exerted by a compressed or stretched spring upon any object that is attached to it.

• The force that is exerted by a fluid on an object moving through it.

Tangential Velocity is defined as:

• The rate of change of angular displacement

• The linear speed of something moving along a circular path

• The force acting perpendicular to the direction of motion

• The acceleration of an object in circular motion

Using the centripetal force equation, if the mass of the car is quadrupled, what happens to the force?

• The force is halved

• The force remains the same

• The force is doubled

• The force is quadrupled

Using the centripetal force equation, if the speed is doubled, what happens to the force?

• The force remains the same

• The force is doubled

• The force is quadrupled

• The force is halved
