Answers
The opposing or supporting force is called friction. Advantages of friction are:
1) Without friction we can't walk or run.
2) Without Friction we can't write on a book or paper.

Explanation:
Friction is a force between two surfaces that are sliding, or trying to slide, across each other. ... Friction always slows a moving object down. The amount of friction depends on the materials from which the two surfaces are made. The rougher the surface, the more friction is produced.
Advantages of friction:
Friction enables us to walk freely.
It helps to support ladder against wall.
It becomes possible to transfer one form of energy to another.
Objects can be piled up without slipping.
Breaks of vehicles work due to friction.
It always resists the motion, so extra energy is required to overcome it.
Friction is a resistance force that slows down or prevents motion, it is necessary for many applications where you might want to hold items or do things and prevent slipping or sliding. Friction is used in car brakes, when we walk or climb a hill, making a fire, skiing down a hill, and more.
