Radian
The angle subtended by a circular arc with length equal to radius
Angular velocity
Rate of change of angle
Angular velocity equation
W equals 2 pie divided by time
Centripetal force
Any force that keeps an object moving at constant speed along a circular path
Centripetal force equation
F equals m x w2 x r
Linear velocity equation
V = r x w
Centripetal acceleration
Acceleration of any object in a circular path
Best way to remember experiment to investigate circular motion
Video of zayd
Investigating circular motion experiment
-bung swung in circle
-weight remain stationary as long as = to centripetal force of the bung
-if centripetal force inc then weight move up vice versa
Sources of centripetal force
Friction, tension,gravitational attraction
