SHM & Circular Motion
SHM = Shadow of an object in uniform circular motion.
Imagine a turntbale with small ball glued to the edge.When light is projected,the shadow of the ball move oscillates back and forth as the turntable rotates
-
Damped Oscillation
-an oscillation the runs down and stops – friction – mechanical energy transforms into thermal energy.
-there must be a damping force (drag force)
