Question
“More is the pressure exerted on the surface, more will be the friction.”
- True
- False
Hint:
- The expression for the frictional force is given as,
F
Where, μ is the coefficient of friction and N is the normal force acting between the body and the surface.
F
Where, μ is the coefficient of friction and N is the normal force acting between the body and the surface.
The correct answer is 'True'.
- The expression for the frictional force is given as,
F
Where, μ is the coefficient of friction and N is the normal force acting between the body and the surface.
- So more the pressure more will be the N hence more will be the friction
- hence above statement is true
F
Where, μ is the coefficient of friction and N is the normal force acting between the body and the 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.
