Motion is defined as phenomenon in which an object move from one place to another over a time.
Generally there are four types of motion: Linear, rotary, reciprocating and oscillating.
Linear motion: In this motion an object moves in a straight line. for example: an athlete running in a straight line.
Rotary motion: In this motion an object moves around an axis. For example: Wheel.
Reciprocating motion: In this motion an object moves in a continuous up and down motion or back-and-forth motion. For example: piston.
Oscillating motion: In this motion an object moves in a swinging motion (backwards and forwards) on an axis. For example: Pendulum.
