Give Newton's three laws ?¿
Answers
Answer:
Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. It may be seen as a statement about inertia, that objects will remain in their state of motion unless a force acts to change the motion.
Newton's Second Law of motion states that the rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of the force. ie., F=ma. Where F is the force applied, m is the mass of the body, and a, the acceleration produced.
Newton's Third Law of Motion - Whenever one body exerts a force on another body, the second body exerts an equal and opposite force on the first body. - Force exerted by first body is action. - Force exerted by second body is reaction. - Every action has an equal and opposite reaction.

- The object will remain stationary or as it is at till external force is not apply to it .
- The object in motion will move with same velocity and in same direction till external force is not applied to it
- The rate of change of momentum is directly proportional to applied force .
- For every action there is reaction force
