Types of motion
Oscillating motion has a curved backwards and forwards movement that swings on an axis or pivot point, eg a swing or a clock pendulum:

In oscillatory motion, an object tends to repeat certain movements in the same pattern repeatedly until it is acted upon by some external force. The movement of an oscillating object can be to and fro, back and forth, or vibratory in nature. In the absence of friction, the oscillatory motion has the ability to go on forever till eternity. For example, a pendulum, flapping of bird wings, etc.

Oscillatory Motion

Here are some examples of oscillatory motion. Oscillations of a pendulum Vibration in a spring Motion of a wheel Movement of a seesaw Vibrations in guitar strings Alternating current in household equipment Electromagnetic waves passing through the air The example below shows a pendulum oscillating about its point of suspension. It passes through points A, B, and C during its oscillations.
