Does the coefficient of kinetic friction depend on the weight of the block.

. Of friction μ friction force Normal reaction So Increase in force of friction and normal reaction will be equal and be deducted completely w. Do you expect them to be the same or different. Where Fk is the force of kinetic friction μk is the coefficient of sliding friction or kinetic friction and Fn is the normal force equal to the objects weight if the problem involves a horizontal surface and no other vertical forces are acting ie Fn mg where m is the objects mass and g is the acceleration due to gravity.

However the coefficient of friction can vary depending on whether the body is moving or not. Does the force of kinetic friction depend on the weight of the block. Answer 1 of 4.

You investigate the force of friction by studying objects moving at constant speed. Does the coefficient of kinetic friction depend on the weight of the block. Does the force of kinetic friction depend on the weight of the block.

Does the force of kinetic friction depend on the weight. Where F friction R normal reaction force and μ coefficient of friction. Does the coefficient of kinetic friction depend on the weight of the block.

Ideally the coefficient of kinetic friction only depends on the nature of the surfaces. Therefore I have come up with the following equation to solve for the coefficient of kinetic friction. A change in angle does not affect the normal force but doesnt a change in angle affect the friction.

It DOES NOT depend on the weight of the bodyonly the frictional FORCE depends on the weight of the body as Fumg where u is the coefficient of friction. Therefore for an object moving on a horizontal plane. So Increase in force of friction and normal reaction will be equal and be deducted completely while division in calculation of cofficient of frictionμ.

How to find force of friction. - Answers No It does not depends on weight of block because this weight of block is being balanced by normal force. The amount of static friction depends only upon the nature of the surfaces in contact rather than the area of the surfaces in contact.

The friction does not vary with the objects weight but with the normal force. Of frictionμ friction force Normal reaction. Does the force of kinetic friction depend on the weight of the block.

As in if the angle is steeper wouldnt the object have a greater propensity to move down the slope thus there will be less friction. The equation expressing the relationship between kinetic-friction force and normal. Therfore a graph of F against R would pass through the origin.

Kinetic also known as sliding coefficient of friction. Does the force of kinetic friction depend on the weight of the block. The coefficient of kinetic friction does not depend on speed.

The higher the mass the higher the force required to impede motion. Joshlm2977 is waiting for your help. The equation for kinetic friction is F coefficient of friction Normal force.

Static friction does not depend upon the area of the surfaces in. There are two types of coefficient of friction. The only force acting on it is kinetic friction.

Choose the normal force acting between the object and the ground. Static coefficient of friction. Why does friction depend on normal force and not the weight of the object.

Does the force of kinetic friction depend on the weight of the block. As a result the coefficient of friction depends on the nature of the surface. Yes the equation for kinetic friction involves Friction coefficient of friction normal force the higher weight of the block the higher normal force and ultimately higher.

Because weight friction force weight normal reaction and. View the full answer. How is weight related to friction.

Yes for an object moving on a horizontal plane R mg where mg weight. Does the force of kinetic friction depend on the weight of the block. This is so because it is the normal force that presses the body on the surface so the greater.

For an object moving on a horizontal plane R mg where mg weight. Do you expect them to be the same or different. How is FF calculated.

Kinetic coefficient of friction also known as sliding coefficient of friction. You will determine µ. Click to see full answer.

Add your answer and earn points. Solution 11 The kinetic friction force fk Uk N N is normal force N mg mg is weight W W. Weight doesnt effect the coefficient of friction.

We also measured the coefficients of static and kinetic friction for a block and determined if the coefficient of kinetic friction does not depend on weight. No weight doesnt effect the coefficient of friction. If F 0 then R must also equal 0 to satisfy the above equation.

The coefficient of kinetic friction can be calculated using mu_k F_kF_n. Compare your coefficients of kinetic friction determined in Part III to that determined in Part II. Compare your coefficients of kinetic friction determined in Part III to that determined in Part II Discuss the values.

Therefore the coefficient of friction depends on the nature of the surface. Does the force of kinetic friction depend on the weight of the block. Does the force of kinetic friction depend on the weight of the block.

4How does doubling the weight of the body. It does not depend on any other factors including the relative speed of the surfaces and the surface area of contact. Therefore for an object moving on a horizontal plane.

The equation for kinetic friction is F coefficient of friction Normal force. I am inclined to answer no because according to my equation it depends on acceleration but on the other hand acceleration. The value of the coefficient of friction varies from zero to one.

Does the coefficient of kinetic friction depend on the weight of the block. Yes because the formula for force of kinetic friction is equal to the coefficient of kinetic friction times the Normal force and the normal force of an object changes as teh weight of the object changes 13. Because weight friction force weight normal reaction and coff.

Actually the coefficient of friction does not change much with the normal force weight of an object.
