What can you say about the relation between weight and friction?

Explain that, for friction due to surface roughness, the frictional force is proportional to the weight of the object being moved across a surface.

How does weight affect friction?

When a body is moving over a horizontal surface, it presses down against the surface with a force equal to its weight, i.e., to the pull of gravity upon it; an increase in the weight of the body causes an increase in the amount of resistance offered to the relative motion of the surfaces in contact.

Does friction force depend on weight?

Solution : Friction does not depend on the mass of the body. It depends on the normal force and the roughness of the surface in contact.

Why does friction increase with weight?

Friction increases with mass because friction depends on the normal force, which is related to the weight of an object, which depends on mass.

What is the relationship among magnitude of friction and weight of the object?

1)N is directly proportional to weight of the body and it also depend on the inclination of the plane with horizontal.so friction force is also directly proportional to weight of the body. 2)if the surfaces in contact are smooth then friction is less and if the surface are rough then the friction force is more.

Weight, Force, Mass

Is friction independent of weight?

"Friction is independent of weight, but depends on normal force between surfaces of contact where friction exists”.

Does reducing weight reduce friction?

To minimize the friction, we need to reduce the contact area between wheels and surface. In addition, we need to reduce the weight of AEV as above said.

What increases friction?

To increase friction, the surfaces in contact have to be made rough. The two surfaces in contact can also be pressed harder to increase force between them. Use of adhesive materials that stick surfaces , also increases friction between them.

Does weight Affect rolling friction?

In addition, weight adds rolling resistance to tires. Extra weight causes a greater deformation of the sidewalls and tread of a tire, thus, increasing the rolling resistance.

Does the amount of friction depend on the weight of the object pressing together?

The amount of friction depends on the weight of the objects pressing together. Q. The rougher the surface, the faster an object will travel over the surface.

Why does friction depend on normal force instead of weight?

The friction force always depends on the magnitude of the force normal to the surface because that is the force that actually presses the surfaces together. Consequently, only the component of the weight that is perpendicular to the surface contributes to the friction force.

Why coefficient of friction is independent of weight?

Solution : If weight of a body is doubled , coefficient of friction does not change . Coefficient of friction is independent of normal reaction . If weight is doubled , normal reaction doubled and correspondingly frictional force doubled , So , coefficient of friction does not change .

What happens to the coefficient of friction if the weight of the body is doubled explain?

Solution : When weight of the body is doubled still then there is no change in coefficient of friction .

Does the coefficient of friction increase when mass increases?

As the mass increases, the static friction increases. This is because the normal force increases as the mass increases.

What is the relation between force and friction?

According to the laws of physics, the force of friction, F_friction, always acts to oppose the force you apply when you try to move an object. Friction is proportional to the force with which an object pushes against the surface you're trying to slide it along.

How frictional force depends upon the mass of the body and on the nature of the surfaces?

When a body is moving over a horizontal surface, it presses down against the surface with a force equal to its weight, i.e., to the pull of gravity upon it; an increase in the weight of the body causes an increase in the amount of resistance offered to the relative motion of all the surfaces in contact.

What is the relation between frictional force and normal force?

Equations. Kinetic friction magnitude is directly proportional to the normal force magnitude and the roughness between the sliding surfaces. Static friction magnitude is directly proportional to the normal force magnitude and the roughness between the sliding surfaces.

How do you describe the friction between a surface and an object with greater?

An object of large mass is pulled down onto a surface with a greater force than an object of low mass and, as a consequence, there is greater friction between the surface of the heavy object than between the surface and the light object. The characteristic of a high friction surface tends to be coarseness.

On which factors force of friction depends?

(1) the material of the bodies in contact. (2) quality of machining of the surface in contact. (3) presence of foreign matter between the surface. (4) area of the surfaces in contact.

What decreases the amount of friction?

Using lubricants such as oil or grease can reduce the friction between the surfaces. When objects are rolled over the surface, the friction between the rolled object and surface can be reduced by using ball bearings.

Does weight increase speed?

Weight affects speed down the ramp (the pull of gravity), but it's the mass (and friction) that affects speed after a car leaves the ramp. Heavier cars have more momentum, so they travel further, given the same amount of friction.

Why does weight affect speed?

Same weight (mass), much different speeds, the variable is friction. Increasing the weight in any fixed friction environment will always decrease the speed with a given applied force.

How does weight affect velocity?

Mass does not affect the velocity of falling objects. Only gravity and air resistance affect the velocity of falling objects.
