Distinguish between circular and oscillatory motions with the help of simple diagrams |
|
Answer» Oscillatory MOTION→ A motion repeating itself is referred to as periodic or oscillatory motion.. Circular motion→ The motion done by a body in circular path is referred as circular motion.. For example, the motion of a pendulum is both oscillatory and periodic but the motion of the wheels of a car is only periodic because the wheels ROTATE in a circular motion. Thus, circular motion is only periodic and not oscillatory because the wheels do not move to and fro about a MEAN POSITION... |
