Answer 2

When two surfaces come into contact, forces are applied by each surface on the other. The part which is tangent to the contacting surfaces is called the frictional force. Friction is a resisting force that acts on a body to prevent or reduce its motion. Friction force acts opposite to the direction of motion.
