Question
Which of the following is not a smooth surface?
Hint:
A smooth surface has no roughness, lumps, or holes. and rough surface is uneven and lots of irregularities
The correct answer is: Surface of tyres
- A smooth surface has no roughness, lumps, or holes. and rough surface is uneven lots of irregularities
- Surface with a minimum amount of friction or no friction is said to be a smooth surface.
- The object can move without any trouble (smoothly) in smooth surface whereas a rough surface is a surface in which there would be a major amount of frictional force present, also it has many singular points, ridges, lump, etc
- As we know that the surface of tyres is rough and uneven so we can say that the surface of a tyre is not a smooth surface.

How does friction affect speed?
Friction is the force opposing one solid object's movement over another. Four categories of friction exist fluid friction, rolling friction, sliding friction, and static friction.
¶The frictional force keeps our feet planted on the ground when we walk on or on the floor. As a result, we frequently slip on icy or slippery surfaces because there is less friction.
¶According to scientists, friction is caused by the interactions of tiny bumps on surfaces as they rub against each other. The bumps on each surface bend and exert force on each other, making it difficult for the surfaces to slip over each other.
