Most forms of conventional movement require friction. For example, a car could not go anywhere if not for the the friction between the rubber tire and the road surface.
No. Objects have to be in contact for there to be friction between them.
The factors that determine the friction force between two sliding objects are the nature of the materials in contact, the normal force pressing the objects together, the surface roughness, and the presence of any lubricants between the surfaces. The coefficient of friction between the materials also plays a significant role in determining the friction force.
Friction is the force that opposes motion between two objects.
Friction force. [opposite force]
The 3 types of friction are static friction (force between stationary objects), kinetic friction (force between moving objects), and rolling friction (force between a rolling object and a surface). Friction is the resistance that one surface or object encounters when moving over another.
Kinetic friction is the type of friction that can best be described as the force between objects that are moving. It occurs when two objects slide or rub against each other.
The force that results from physical contact between two objects is called contact force. This force can include friction, tension, normal force, and applied force.
Increasing the force pressing the two objects together will increase the frictional force between them. This is because the frictional force is directly proportional to the normal force acting between the objects. As you push harder, the surfaces of the objects come into more contact, leading to greater friction.
Friction is the force between objects that resists forward motion. It acts in the opposite direction to the force applied and can slow down or stop the objects from moving. Friction is caused by the contact between surfaces and is affected by factors such as roughness and pressure.
