Plse tell me ans from yourself

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.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
