Give examples for Newton's third law .

Explanation

(i) When birds fly , they push the air downwards by their wings ( Action ).
(ii) The air pushes the bird upward ( Reaction ).
(iii) When a person swims , he pushes the water using hands backwards ( Action ), the water pushes the swimmer in forward direction ( Reaction ).
(iv) Rockets expel ges at high velocity ( Action ). The downward moving gas pushes the rocket in upward direction ( Reaction ) .
(v) When we fire a bullet , the gun recoils back , Bullet is moving forward (action ) . The gun equalise this forward action by moving backward ( reaction ) .
