In a freely falling body what is constant?
QGP:
For a freely falling body, the first thing that's constant is it's acceleration. But that's when you neglect air resistance
When you consider air resistance, then there exists a viscous force, a resistive force opposing motion. It is directly proportional to the speed of the body
So, as body falls farther, it's speed increases, so resistive force increases and acceleration decreases
There finally comes a moment when the resistive force finally balances the gravitational force
At this point, the body starts moving with constant velocity, called the terminal velocity
Thus, after some time, the acceleration of the freely falling body becomes zero, and it's speed becomes constant

Hey there!
In a freely falling body acceleration is constant. Acceleration is defined as the rate of change of velocity at a unit time.
Here, it means when a body is falling freely to the ground then the velocity of that body will change at the constant rate.
Hope it helps you!

In a freely falling body acceleration remains constant.
acceleration is the rate of change of velocity of an object with respect to time
Si unit of acceleration = m/s², m·s⁻², m s⁻²
any object's average acceleration over a period of time is its change in velocity which is then divided by the duration of the period
