Overview
Uniform circular motion describes the movement of an object traveling at a constant speed in a circular path. Even though speed is constant, the object is accelerating because its direction is constantly changing.

Pro Tips
Period (T) is the time for one complete revolution.
Angular velocity (ω) is measured in radians per second.
The inward 'centripetal' acceleration is always perpendicular to the linear velocity.

Fun Facts
"Satellites in geostationary orbit have a period of exactly 23 hours, 56 minutes, and 4 seconds."
"A CD spinning at 500 RPM has a much higher linear velocity at its outer edge than near its center."
"The Hammer Throw in the Olympics is a classic example of circular motion generating high linear velocity."
