How does a washing machine wash clothes ?

This everyday household appliance ingeniously applies Newtons first law of motion.

According to Newtons first law also called as law of inertia ,states that,object at rest stays at rest  and object in motion stays in motion with the same speed and in  same direction unless acted upon by an external force .

The device that is designed to wash laundry consists of two steel tubs which are inner tub and outer tub whose main role is to prevent water  from spilling to other parts of machine.

Holes in the walls of drum

In the washing machine's spin cycle, the drum rotates rapidly , its inner walls continually pushing the clothes into a circular path.This directional change means the clothes are accelerating and thus subject to external force.The rapid mechanical spinning can exert quite substantial force,as anyone who has witnessed the loud noise of an unevenly loaded washer can attest. But holes in the walls of the drum mean no such inward forces act on the water .The wash water is permitted to fly off along the linear path , effectively wringing the clothes against the spinning drum
