Periodic motion - object continuously moves over the same path
period - amount of time one cycle or revent takes to occur
frequency - how man times per second the event happens |
f= 1/T
T=1/f |

objects that move in a circle are constantly accelerating because they are continuously changing direction - even travelling at constant speed
centripetal acceleration - the acceleration experienced by any object moving in a circular path |
Centripetal motion
ac=(v^2)/r --acts towards centre of circle b/c there is acceleration there must be an acceleration course
|

|
Centripetal Force (Fc) - magnitude of which can be calculated using
Fc=mac OR Fc= (mv^2)/r
Fc keeps objects moving in circle |
