How is simple harmonic motion similar and different from that of a ball bouncing on a hard floor? (Hint: One similarity and two differences)
Both are oscillatory motion .
Harmonic motion are periodic and repeat after a fixed interval of time ,but the amplitude of bouncing ball continue decreases ,it is non periodic motion .
In harmonic motion energy remain conserved ,but in bouncing ball energy continuesly decreases and finally it will come in the rest .
