The work done by a body against friction always results in :
A
Loss of kinetic energy
B
Loss of potential energy
C
Gain of kinetic energy
D
Gain of potential energy
Answer
Loss of kinetic energy
Explanation
Solution
Friction always opposes motion. A body does work against friction at the expense of its kinetic energy.
Hence, the work done by a body against friction always results in loss of kinetic energy.
