Solution

Frictional Force:
Friction is a resistive force that opposes the motion of a body.
It occurs at the surface that is in contact with the moving object.
This phenomenon occurs according to Newton's third law of motion which states that every action has an equal and opposite reaction.
Disadvantages of Friction:
Heat is generated at this surface of contact due to the opposing force of friction.
This causes wear and tear on the material of the moving body.
Hence, more work is required to put on a moving body so that it can overcome the force of friction and move forward.
When excessive heat is generated, it may cause a spark or fire and cause damage to the components or machines.
When a sudden frictional force is applied to a moving body it may cause harm or accidents.

Disadvantages of friction:

It always resists the motion, so extra energy is required to overcome it.
It causes wear and tear of machines.
It decreases the life expectancy of moving parts of vehicles.
Since friction is very useful in some cases while harmful in some cases, friction is called a necessary evil.

What is the bad thing about friction? ›

I have generally seen friction as a bad thing. Friction prevents us from moving fast, makes it harder to get things done efficiently and makes us slower. Before we go any deeper let's define what friction is. Friction is anything that slows us down and prevents us from moving faster.
