    - According to Newton's third law, every action has an equal and opposite reaction. If a body A exerts force on another body B then, simultaneously equal force is exerted by body B of same magnitude but in direction opposite to that of body A.

    - According to Newton's second law, the vector sum of external forces is equal to mass of object which is multiplied by acceleration of the object. It is represented by F = ma. It is also defined as the net force acting on an object which is equal to the rate of change of its linear momentum.

    - According to Newton's first law, a body remains at rest or in continuous motion unless an external force acts on it.
