Answer
Newton's third law
Reason — Newton's third law of motion states that : In an interaction of two bodies A and B, the magnitude of reaction (i.e., the force FAB applied by the body A) is equal in magnitude to the action (i.e., the force FBA applied by the body A on the body B), but they are in directions opposite to each other.
Hence, the law explains how a force acts on a body or an object.

A bullet of mass 50 g moving with an initial velocity of 100 m s-1, strikes a wooden block and comes to rest after penetrating a distance 2 cm in it. Calculate (i) initial momentum of the bullet (ii) final momentum of the bullet, (iii) retardation caused by the wooden block, and (iv) resistive force exerted by the wooden block
Newton's third law —
- defines the force qualitatively
- defines the force quantitatively
- explains the way a force acts on a body
- gives the direction of force.
To every action there is always :
- an equal reaction
- an equal and opposite reaction
- an equal reaction in the same direction
- none of these
Action and reaction act on the —
- same body in opposite directions
- different bodies in opposite directions
- different bodies, but in same direction
- same body in same direction.
