If an object is falling freely from certain height towards the surface of earth, its total mechanical enrgy ……………

A

decreases

B

increases

C

does not change

D

goes on increasing and decreasing

Text Solution

Verified by Experts

The correct Answer is:
C
Total mechanical energy
= Potential energy `E_(p) +` Kinetic energy `E_(k)`
The decreases in potential energy of a free falling object is equal to increases in kinetic energy.
