No, coefficient of friction is dependent on the materials in contact, not their mass. However the FORCE of friction will increase as the mass increases in this case.

What is the coefficient of kinetic friction between the 13.0kg wooden crate and the horizontal force of 31N of the floor?
The coefficient of kinetic friction can be calculated using the formula: coefficient of kinetic friction = force of kinetic friction / normal force. The force of kinetic friction can be found using the formula: force of kinetic friction = coefficient of kinetic friction * normal force. Given the force of 31N and normal force equal to the weight of the crate (mg), you can calculate the coefficient of kinetic friction.
What is the effect of decreasing the surface area of the block in contact with the table on the coefficient of kinetic friction?
Decreasing the surface area in contact with the table will increase the pressure at that contact point. This can lead to an increase in the coefficient of kinetic friction, as the roughness at the microscopic level can become more significant.
What is coeffitient of stactic n kinetic friction?
The coefficient of static friction is the ratio of the force required to move an object to the force pressing the surfaces together when the object is not moving. The coefficient of kinetic friction is the ratio of the force of friction between two objects in motion to the force pressing them together. Both coefficients are dimensionless values specific to the two surfaces in contact.
How can an adjustable inclined plane be used to measure the coefficient of static friction and coefficient of kinetic friction?
An adjustable inclined plane can be used to measure the coefficient of static friction by gradually increasing the angle of the incline until the object just begins to slide. The coefficient of static friction can be calculated using trigonometry. The coefficient of kinetic friction can be measured by setting the incline at a known angle and measuring the acceleration of the object as it slides down.
Is coefficient of friction or coefficient of limiting friction are same?
No, the coefficient of friction and the coefficient of limiting friction are not the same. The coefficient of friction is a constant value that describes the relationship between the force of friction between two surfaces, while the coefficient of limiting friction specifically refers to the maximum value of friction force that can be exerted before sliding occurs.
What is the formula for the coefficient of kinetic friction?
The formula for the coefficient of kinetic friction is μk = Fk/N, where μk is the coefficient of kinetic friction, Fk is the force of kinetic friction, and N is the normal force. The coefficient of kinetic friction represents the level of resistance between two surfaces in contact while they are in motion.

The coefficient of kinetic friction can be calculated using the formula: coefficient of kinetic friction = force of kinetic friction / normal force.

Given the force of 31N and normal force equal to the weight of the crate (mg), you can calculate the coefficient of kinetic friction.
What are some ways to increasing friction?
Use a surface that has a higher coefficient of static/kinetic friction and/or add more force downwards on the object.
Which coefficient of friction is greater static or kinetic?
The coefficient of static friction is greater than the coefficient of kinetic friction. Static friction occurs when an object is at rest and must be overcome to start moving, leading to a higher coefficient compared to kinetic friction, which occurs when an object is already in motion.
What is the coefficient of kinetic friction between aluminun and felt?
The coefficient of kinetic friction between wool felt and aluminum is about 0.24 to 0.26.
What is the effect of decreasing the surface area of the block in contact with the table on the coefficient of kinetic friction?
Decreasing the surface area in contact with the table will increase the pressure at that contact point. This can lead to an increase in the coefficient of kinetic friction, as the roughness at the microscopic level can become more significant.
Why coefficient of static friction is larger than kinetic friction?
The coefficient of static friction is typically larger than the coefficient of kinetic friction because it represents the maximum force required to start an object in motion, overcoming the initial static friction. Once the object is in motion, the kinetic friction is usually less because the surfaces are already moving relative to each other, resulting in lower resistance.
What is the coefficient of kinetic energy?
The coefficient of kinetic energy is not a standard term in physics. It is more common to refer to the coefficient of kinetic friction, which represents the amount of friction between two surfaces in contact when one is moving relative to the other. This coefficient depends on the surfaces in contact and is a dimensionless quantity typically denoted by the symbol μ.
Why coefficient of friction is less than static friction?
The coefficient of static friction is higher than the coefficient of kinetic (or sliding) friction because it takes more force to overcome the initial static friction and start an object moving than to keep it moving once it is already in motion. Static friction is present when an object is at rest, while kinetic friction occurs when an object is moving.
What is the coefficient of kinetic friction between aluminum and cork?
0.35, approximately
What can you conclude about the effect of friction in the pulley on the value of K?
Friction in the pulley will decrease the efficiency of the system, causing an increase in the value of K. This is because some of the input energy is lost to overcoming friction, resulting in a higher value of the kinetic friction coefficient.
What is more sliding friction or static friction?
static friction is higher in most cases, if you're talking about the coefficient of static or kinetic friction
