Question

for freely falling object we can write newton second equation of motion as

Answer 1

the rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of force...which means that the rate of change of the product of mass of the object & the velocity at which it was falling is equal to the force at which it was thrown in the direction where it was thrown .

Answer 2

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.
