Detailed explanation-1: -Friction is an everyday force that is created by two surfaces interacting. When these surfaces slide against each other, this interaction increases the thermal energy of the two surfaces (the temperature goes up).

Detailed explanation-2: -How does friction affect motion? Friction always opposes the motion and reduces the speed at which the object moves on the surface. It will turn some of the kinetic energy of an object into heat energy, thereby reducing the speed.

Detailed explanation-3: -Kinetic friction is defined as a force that acts between moving surfaces. A body moving on the surface experiences a force in the opposite direction of its movement.

Detailed explanation-4: -Friction is produced due to the irregularities between surfaces. Thus, when these surfaces rub against each other they produce heat.

Detailed explanation-5: -Therefore, friction is the force acting on a moving object that transforms kinetic energy to heat energy.
