Answer:
Friction is a force which is always opposite to the direction of motion. Friction is also called as the 'opposing force'. Under high friction the body can't move, it is very hard to move. Under low friction the body can move easily and fastly.
Functions and advantages of friction:
- We can walk across a surface without slipping due to friction.
- Writing with a pen in a paper is due to friction.
- Jumping out of the airplane with a parachute is due to friction.
