Question

if the surface of objects are pressed harder while moving in contact with with each other, will the frictional force increase ? explain with the help of diagram ?​

Answer 1

$\mathfrak{\huge{\blue{\underline{\underline{★ Aditya ★}}}}}$

It is obvious that the force of friction will increase if the two surfaces are pressed harder. So, the sliding friction is slightly smaller than the static friction and you find it somewhat easier to move the box already in motion than to get it started.

Answer 2

Explanations

The friction force depend on the the surface and also the mass of the object

The friction force depend on the the surface and also the mass of the objectSimply it oppose the motion of an object

The friction force depend on the the surface and also the mass of the objectSimply it oppose the motion of an objectWhen u press it harder u need some force that force add up to the mass

The friction force depend on the the surface and also the mass of the objectSimply it oppose the motion of an objectWhen u press it harder u need some force that force add up to the massHere you have to also specify that mass here means the force not the real mass as the real mass of the object
