Question

Explain 3 laws of motion briefly.

Answer 1

first law states that any object in motion remains in motion or that in rest remains in rest until any external unbalanced force is applied
second law states that the rate of change of momentum is directly proportional to force applied
third law is every action has equal and opposite reaction

Answer 2

1st law: if a body is at rest ,it will be at rest. If a body is in motion it will be in motion until and unless any external unbalanced force is applied on it 2nd law: the rate of change of momentum of the body is directly proportional to the applied force which takes place in the direction of force. 3rd law: whenever one body exerts a force on another body, there body exerts an equal and opposite force on the first body, that is to every action there is equal an opposite reaction but action and reaction act on two different bodies.
