What are Newton's Laws of Motion?

Newton's first law of motion

=======================

Newton's first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force (a = dv/dt = 0)

Newton's second law of motion

==========================

The second law states that the rate of change of momentum of a body over time is directly proportional to the force applied, and occurs in the same direction as the applied force (F = dp/dt - where p is the momentum of the body) (F = ma)

Newton's third law of motion

========================

Newton's third law states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction (FA = −FB).

Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object (FA = −FB).

For every action there is a reaction equal in magnitude and opposite in direction.

Answer 2

First law states that if no net force acts on an object, its velocity is constant.

Second law states that the sum of all forces acting on an object are equal to its mass multiplied by its acceleration.

Third law states that when one body exerts a force on another body, there is an equal and opposite force exerted on the second body by the first body.
