Circular Motion P.159

Circular Motion P.159 Section 2

Uniform Circular Motion • Definition: – movement of an object, – at constant speed, – Around a circle with a fixed radius

Uniform Circular Motion • Average velocity in linear motion is calculated from:

vavg

x  t

• But for an object in circular motion:

vavg

r  t

Centripetal acceleration EQUATION 2

v ac  r

Centripetal Force

FR  mac

Period of revolution (Time)

4r ac  2 T
