Question

if body is moving downward on the earth under gravity what will be second equation of motion for that body

Answer 1

Explanation:

Newton's second law of motion states that the acceleration of a system is directly proportional to and in the same direction as the net external force acting on the system, and inversely proportional to its mass. ... If the only force acting on an object is due to gravity, the object is in free fall.

There are two forces acting upon the person. The force of gravity exerts a downward force. The floor exerts an upward force. Since these two forces are of equal magnitude and in opposite directions, they balance each other.
