The force of friction depends on the nature of the surfaces in contact and the normal force pressing the surfaces together. A rough surface will create more friction compared to a smooth surface, and increasing the normal force pressing the surfaces together will increase the friction force.

Friction opposes the motion of objects by acting in the opposite direction to their movement. It can cause objects to slow down or come to a stop. The amount of friction depends on the surfaces involved and the force pressing them together.
The two factors that determine the amount of friction on an object are the nature of the surfaces in contact and the force pressing the surfaces together. Rougher surfaces and greater force lead to higher friction. Smooth surfaces and lower force result in lower friction.
Friction affects the movement of objects by creating resistance. Two things affected by friction are the speed of an object and the amount of force needed to move it. Friction can slow down the speed of an object and require more force to overcome, making it harder to move.
All things are having roughness on that faces.Two parts are moving at touched position.That time two parts roughness is making friction with vibrate are sound.
Friction is what holds, stops things from moving. if there was no friction then things would be on the move 24/7.
Friction slows things down.
The amount of friction between two objects is affected by the type of surfaces in contact (smooth or rough) and the force pressing the surfaces together (normal force). Rough surfaces and increased normal force typically result in higher friction.
1) friction thats lows things down is called dynamic friction 2) friction that stops things is called static friction 3) most of friction makes heat ( rubbing hands together )
Friction is important because without friction we would be sliding and slipping everywhere as friction slows down and stops things. Friction occurs when two things touch or make contact.
When two objects grind past each other, the force generated is called friction. Friction opposes the motion between the two surfaces and is influenced by factors such as the materials involved, their roughness, and the normal force pressing them together.
