Which one of the following forces is a 'dissipative force'?

Options

A. Electrostatic force
B. Magnetic force
C. Gravitational force
D. Frictional force

Answer

D

Explanation

A dissipative force counter acts motion. Its direction is opposite to the direction of the velocity vector. Dynamic friction is a dissipative (non-conservative) force: It dissipates energy (mainly through heat and sound), and energy lost by moving in one direction.
