Explanation:
Frictional force is a force that opposes the motion between two surfaces that are in contact with one another.
Frictional force opposes motion and it is directed opposite the direction of motion.
There is also frictional force between liquids too.
- Enough force must be supplied in order to overcome this frictional force so as to make a body move.
- In humans, motion wouldn't be possible without the frictional force.
