Is Kinetic friction is affected by the weight of the object?
Kinetic friction is independent of the weight of the object. It is determined by the nature of the surfaces in contact and the force pressing them together. The weight of the object affects the normal force, which in turn affects the frictional force, but the coefficient of kinetic friction remains constant for a given surface.
What happens to coefficient of friction when weight of body is doubled?
If the weight of a body is doubled, the coefficient of friction does not change. The coefficient of friction is a constant for a given pair of materials and surfaces, and it does not depend on the weight of the body.
What is the coefficient of kinetic friction between a 400kg safe and the the floor when 760N are applied to the right?
The coefficient of kinetic friction can be calculated by dividing the force of friction (760 N) by the normal force between the safe and the floor. The normal force is equal to the weight of the safe, which is the product of the mass (400 kg) and the acceleration due to gravity (9.8 m/s^2). After finding the normal force, you can calculate the coefficient of kinetic friction by dividing the force of friction by the normal force.
What happened to the coefficients of friction as the weight increases?
Nothing. The coefficient of friction is constant, as it is dependent on the surfaces that are interacting. Normal force increases as an objects mass increases (Be careful with the word "weight", as it denotes the effect of gravity) in a constant gravitational field. This normal force is what causes an increase in friction.
The amount of friction divided by the weight of an object forms a unitless number called the of friction?
The amount of friction divided by the weight of an object forms a unitless number called the coefficient of friction. It represents the relationship between the force of friction and the normal force acting on an object. A higher coefficient of friction indicates greater friction between the surfaces.
Does the coefficient of kinetic friction depend on the weight of the block?
No, It does not depends on weight of block because this weight of block is being balanced by normal force. So by increasing weight of block, there is no effect on coefficient of friction.
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.

How do you find kinetic friction without the coefficient?
You can find the kinetic friction force by measuring the normal force acting on the object and the net force experienced by the object when it is in motion. By applying Newton's second law (F = ma), where a is the acceleration of the object, you can calculate the kinetic friction force without knowing the coefficient.
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.
The amount of friction divided by the weight of an object forms a unitless number called the of friction?
The amount of friction divided by the weight of an object forms a unitless number called the coefficient of friction. It represents the relationship between the force of friction and the normal force acting on an object. A higher coefficient of friction indicates greater friction between the surfaces.
Which force slows down a ball when it moves?
The force of friction between the ball and the surface it is rolling on is responsible for slowing it down. Kinetic friction acts in the opposite direction of the ball's motion, converting some of its kinetic energy into heat.
What should the graph of force of friction vs total weight look like?
The graph of force of friction vs total weight is typically linear, following the equation of force of friction = coefficient of friction * total weight. As total weight increases, the force of friction also increases proportionally. The slope of the graph represents the coefficient of friction.
A 2.0 kg wood box slides down a vertical wood wall while you push on it at a 45 angle. What is the force applied to slide the box down at a constant speed?
The force applied to slide the box down at a constant speed is equal to the force of kinetic friction acting against the box. This force is given by the equation: friction force = coefficient of kinetic friction * normal force. Since the box is sliding down the wall, the normal force is equal to the weight of the box. Therefore, the force applied is equal to the coefficient of kinetic friction * weight of the box.
