Underline the Correct Alternative Work Done by a Body Against Friction Always Results in a Loss of Its Kinetic/Potential Energy - Physics

Underline the correct alternative:

Work done by a body against friction always results in a loss of its kinetic/potential energy

Solution 1

Kinetic energy

The work done against the direction of friction reduces the velocity of a body. Hence, there is a loss of kinetic energy of the body

Solution 2

Kinetic energy, because friction does its work against motion.
