Question

Two different masses are dropped from same heights, then just before these strike the ground, the following is same

• A. Kinetic energy
• B. Potential energy
• C. Linear momentum
• D. Acceleration

Answer 1

The correct option is D Acceleration

Both objects with different masses will attain the same velocity $v$ when strike the ground because acceleration and height are the same.

But Kinetic energy $=\frac{1}{2}m{v}^2$,

Potential energy $=\frac{-GMm}{r}$ and linear momenum $P=mv$ depend upon mass also, so they will change, but the acceleration due to gravity is same throughout the height.
