**Uniform Circular Motion:**

Motion that happens on a circular path, but with a CONSTANT speed.

ds = Arc Length AKA linear distance traveled

r = Radius

**Revolution:**

2pi radians OR 360 degrees

**The kinematic equations work where:**

x = theta

v = angular velocity

a = angular acceleration (constant)

**Angular Velocity:**

The rate of change of the angle.

Unit is radians per second.

**Linear Velocity:**

How much the object/disk is being moved forward.

**Centripetal Acceleration:**

The magnitude of velocity doesn’t change, BUT the direction does, which means there is always some form of acceleration.

This means that the acceleration happens inward of the disk.

**Centripetal Force:**

This can simply be found by multiplying the mass of the object with its centripetal acceleration.

**Angular Acceleration:**

The change in angular velocity.

**Linear Acceleration:**

How much the forward motion of the object/disk is being changed.
