Centripetal force is directed:

Towards the center of the circle
Away from the center
Tangent to the circle
Along the radius but outward

Centripetal acceleration depends on:

Velocity and radius
Mass only
Time only
Force only

The period of revolution is:

Time for one complete revolution
Distance traveled in one second
Velocity at any instant
Number of revolutions per second

The frequency of revolution is:

Number of revolutions per unit time
Time for one revolution
Linear speed
Centripetal acceleration

Uniform circular motion means:

Speed is constant, direction changes
Both speed and direction are constant
Acceleration is zero
Force is zero

Formula for centripetal force is:

F = mv^2/r
F = mr^2/v
F = m/r^2
F = v^2/mr

If velocity increases, centripetal force:

Increases
Decreases
Remains constant
Becomes zero

Centrifugal force is:

Fictitious outward force
Real inward force
Centripetal force
Gravitational force

Angular velocity is:

Rate of change of angle with time
Linear speed
Distance traveled
Acceleration

The acceleration towards the center is given by:

a = v^2/r
a = r^2/v
a = v/r^2
a = r/v^2
