Out of the four physical quantities associated with the motion of an object viz. force, velocity, acceleration and momentum, which one remains constant for all bodies large or small undergoing free fall?
Acceleration remains constant which is acceleration due to gravity.
Velocity changes but the rate of change of velocity remain the same.
As mass is invariant for and object and acceleration is the same in this case so, force remains same as it is the product of mass and acceleration.
Momentum is not constant due to variation in velocity.
