What is friction????????
Answers
Answer:
━━━━━━━━━━━━━━━━━━━━━━━━━━
When the surface of one body moves tends to move on the surface of another body, then a forces generated which opposite the relative motion of the two bodies. This force is called Frictional Force or Friction.

➠It is the resistance produced when a rolling body moves over a surface. Rolling friction has a lesser magnitude than sliding friction. For example, small wheels in the suitcase of very less friction (rolling friction) and make it easy to carry heavy luggage.
➠This is the frictional force between two surfaces when one body or object moves or attempts to move over the other. Sliding friction is the moment of force required to retain the state of motion of the moving object at the same speed. For example, when you apply force to an already moving box to keep it moving on the floor it with the same speed, the force determine sliding friction.
➠It is the friction that works between two surfaces which are in contact, but there is no relative movement between them. Static friction is the amount of force applied at the instant when an object starts moving from its state of rest. For example, when you push a heavy box on the floor.
