Question

explain newtons laws of motion

Answer 1

Firat law: An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. second law:Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object). third law: For every action there is an equal and opposite re-action.

Answer 2

According to Newton's first law of motion ,if a body is in a state of rest it will remain in the state of rest and if it is in state of motion it will remain moving in the same direction with the same speed unless an external force is applied to it.
According to Newton's second law of motion ,the rate of change of momentum of a body is directly proportional to the force applied on it and the change in momentum takes place in the direction in which the force is applied.
According to Newton's third law of motion to every reaction there is always equal and opposite reaction
