Question

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

Answer 1

When a body is undergoing free fall, it's acceleration will remain constant for all bodies which is equals to 9.8 m/s².
If we think that the velocity is keep changing in free fall then why not acceleration.
Yes, velocity is changing, but the rate of changing velocity is constant here, which is called acceleration.
Now coming to force, force = m×a
this means, greater the mass, greater will be the force.
About velocity, if velocity would be constant, then acceleration must be zero, as we know that, acceleration is the rate of change of velocity.
And in free falling body, acceleration is g and not zero.
Last is momentum, which is the product of mass and velocity which is not constant for bodies undergoing free fall.

Answer 2
