$\: \huge \underline{ \bf{ \red{Answer}}}$

❥Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.

❥Friction is desirable and important in supplying traction to facilitate motion on land. Most land vehicles rely on friction for acceleration, deceleration and changing direction. Sudden reductions in traction can cause loss of control and accidents.

❥Friction is a non-conservative force - work done against friction is path dependent. In the presence of friction, some kinetic energy is always transformed to thermal energy, so mechanical energy is not conserved.
