what is the relationship between friction coefficient and normal force?
160124
Static friction magnitude is directly proportional to the normal force magnitude and the roughness between the sliding surfaces. The coefficient of friction is the ratio of the magnitude of frictional force divided by the normal force magnitude.

The normal force is a force perpendicular to the surface on which the object is laying. ... The reaction force of the normal force is the force the object exerts on the surface it is laying upon. The normal force IS NOT the reaction force of gravitational force, it is only equal in magnitude in a few situations!

Part of the standard model of surface friction is the assumption that the frictional resistance force between two surfaces is proportional to the normal force pressing them together. A common exception occurs in snow where greater traction occurs by having wider tires with lower pressure.

Friction is a general term. If you are referring to frictional force, then it's unit is Newtons (N). It's an opposing force and always acts opposite to the direction of motion. If you are talking about frictional coefficient (u), then it is dimensionless.

Answer: Friction is the force which opposes the motion. Friction is the reason why we can walk or the vehicles could move or to write something on the board, hence it is advantageous. On the other hand, as a portion of energy gets wasted to overcome friction, it has some bad effects too.

The normal force is usually symbolized by N . In many cases the normal force is simply equal to the weight of an object, but that's only when the normal force is the only thing counteracting the weight. That is not always true, and one should always be careful to calculate any force by applying Newton's second law.

The normal force is just one component of the contact force between objects, the other component being the frictional force. ... In many cases the normal force is simply equal to the weight of an object, but that's only when the normal force is the only thing counteracting the weight.

friction: A force that opposes two objects sliding against each other. Friction acts in a direction along the flat surface of an object. normal force: The force exerted by the ground or other object that prevents other objects from going through it.

The normal force is a force perpendicular to the ground that opposes the downward force of the weight of the object.

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 pounds), the coefficient of friction is dimensionless. The coefficient of friction has different values for static friction and kinetic friction.

The Force of Static Friction keeps a stationary object at rest! Once the Force of Static Friction is overcome, the Force of Kinetic Friction is what slows down a moving object!

Friction is a nonconservative force, and there are others. Any friction-type force, like air resistance, is a nonconservative force. The energy that it removes from the system is no longer available to the system for kinetic energy.

A value of 1 means the frictional force is equal to the normal force. ... A coefficient of friction that is more than one just means that the frictional force is stronger than the normal force. An object such as silicone rubber, for example, can have a coefficient of friction much greater than one.

Friction is a force that resists the relative motion between two objects or materials. The causes of this resistive force are molecular adhesion, surface roughness, and deformations. ... But surface roughness is a factor when the materials are rough enough to cause serious abrasion. This is called the sandpaper effect.

Ideally, the coefficient of kinetic friction only depends on the nature of the surfaces. It does not depend on any other factors, including the relative speed of the surfaces and the surface area of contact. You will determine µ. You investigate the force of friction by studying objects moving at constant speed.

Static friction is friction between two or more solid objects that are not moving relative to each other. For example, static friction can prevent an object from sliding down a sloped surface. The coefficient of static friction, typically denoted as μs, is usually higher than the coefficient of kinetic friction.

Normal force (N) = 10 kg × 9.8 (acceleration from gravity) = 98 N. Force from kinetic friction (Fr) = 0.5 × 98 N = 49 Newtons. Force from acceleration (Fa) = 10 kg × 1 m/s2 = 10 Newtons. Total tension = Fr + Fa = 49 + 10 = 59 Newtons.
