We know that friction is the resisting force between any two surfaces in the opposite direction of the motion. We can’t believe in a world without friction. Friction always works in the direction opposite to the direction in which the object is moving or trying to move.
Friction and its importance
Friction is between solid surface, layers of fluid, and also between any two materials. If there is no friction, then most of the tasks such as walking on the road, writing on a board, sliding off the table, etc., would become difficult. Therefore, friction is one of the important forces that is needed for a smooth life.
- The reason why friction is so important to our world is that it affects everything in motion.
- When any object moves, slipping or sliding in one direction, friction is acting in the opposite direction.
- Friction changes or tends to change the moving object from moving by reducing its speed to zero or stopping the stationary objects from moving.
- It is possible to make a car move on the road because of friction. If there were no friction, the car would have slipped.
