Dear Student,
There are three laws laid by newton . They describe the relation between 1) Force applied 2) Motion in response of the force
The three laws are -
First law: An object either remains at rest or continues to move at a constant velocity, unless acted upon by an external force.
Second law: F = ma. The vector sum of the forces F on an object is equal to the mass m of that object multiplied by the acceleration vector a of the object.i.e. force is equal to the rate of change of momentum.
Third law: When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body
