First Law of Motion



First law of motion

A body continues to be in its state of rest or in uniform motion in a straight line unless an external unbalanced force is applied on it.


Newton's first law in practical scenarios

Some applications of Newton's first law in real life scenarios are:
1. A suitcase kept in the train remains in rest w.r.t the train unless brakes are applied or train gains speed.
2. Passengers in the bus fall forward when brakes are applied.
