Question

when a paratrooper jump from hight its weight and normal reaction are equal so why he moves downward​

Answer 1

Answer:

The downwards force due to gravity is bigger if the object is heavier, but the braking force is the same if the parachutes are the same size. This leaves the heavier object subjected to a greater net force in proportion to its mass, so it accelerates faster (Newton's Second Law).

Answer 2

because of gravity example when the magnet is placed at down and a nail is brought near it so it attracts it that is the logic .
