Q. 26 A body falls towards earth in the air. Will its total mechanical energy be conserved during the fall? Justify'.
Hint: Total mechanical energy is conserved if all forces are conservative.
Step 1: Interpret the answer
NO, the total mechanical energy of the body falling freely under gravity is not because a small part of its energy is utilized against the resistive force of the air. which non-conservative force. In this condition. the gain in KE < loss in PE.
