Friction is a force that opposes relative motion between surfaces in contact. One of the simpler characteristics of friction is that it is parallel to the contact surface between surfaces and always in a direction that opposes motion or attempted motion of the systems relative to each other. If two surfaces are in contact and moving ...

Why friction force does not depend on the area of contact?

WebIt is a contact force. Based on the type of motion between the two objects, the force of friction can be classified into four broad categories. Types of Friction 1. Static Friction. A force of friction that acts between an object and a surface on which the object is placed is known as static friction.

Webcoefficient of friction, ratio of the frictional force resisting the motion of two surfaces in contact to the normal force pressing the two surfaces together. It is usually symbolized by the Greek letter mu (μ). Mathematically, μ = F/N, where F is the frictional force and N is the normal force. Because both F and N are measured in units of force (such as newtons or … WebA frictional force acts on the objects in motion that acts in a direction opposite to the direction of the motion of the object. Friction resists the motion of a body when it is in close contact with another body, hence it is a contact force. The muscular force is also a … WebIt's usually stated that the friction force is independent of the area of contact (Amontons' Second Law). I've always thought that this shouldn't be true, because the atraction between molecules would be higher and there would be more peaks. I've read that this is important for rubber surfaces. Is it important for nonelastic materials, like wood? remember ellsworth
