Question

Out of the four physical quantities associated with the motion of an object viz, velocity, acceleration,and momentum which one remain constant for all bodies large or small undergoing free fall

Answer 1

As velocity goes on increasing during free fall so its not constant.
Acceleration may be constant
As we know momentum p=mv here m mass is constant put velocity changes. during free fall hence momentum is not constant
Overall acceleration is constant during free fall
thibk so it will help you

Answer 2

motion is out coverage and acceleration object momentum they are large amount Odie's object
