What is the definition of friction?

  1. An area in front of you that you can see sharply

  2. Energy of motion

  3. Energy produced by two objects rubbing against each other

  4. Force with which one moving object hits another

The correct answer is: Energy produced by two objects rubbing against each other

Friction is defined as the energy produced by two objects rubbing against each other. When two surfaces come into contact with each other and move in relation to one another, the friction between them resists their motion. This resistance is caused by the roughness and irregularities of the surfaces, which interlock and create a force that opposes motion. Therefore, option C accurately defines the concept of friction.
