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.

How do you find kinetic friction without the coefficient?
by experiment. attach a pulley to the edge of a table. attach a known weight to a string through the pulley to another known weight on the table-top. put the particular surface who's coefficient of friction you wish to measure between the table top and the second known weight set on the table top. allow the first know weight to fall. measure its rate of descent. compare its rate of descent with that of the free fall acceleration of gravity for your particular latitude. you now have all the data you need to figure out the coefficient of kinetic friction. can you do that yourself or do you need to know more?
Does coefficient of kinetic friction depend on weight?
Yes, It does not vary with lesser relative velocity between surfaces.But when the speed exceeds 10m/s ,due to heat produced between the surfaces the co-efficient increases.
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.
On a flat surface the coefficient of friction is a ratio between and the weight of the object?
The force of friction!
The amount of friction divided by the weight of an object forms a unitless number called the of friction?
I think it is the coefficient of friction
Is Kinetic friction is affected by the weight of the object?
Yes
What is the amount of friction divided by the weight of an object forms a unitless number called the blank of friction?
coefficient
Is it true that weight affects the amount of friction between the object and a surface?
Yes. Weight, being a force perpendicular to the surface, affects the magnitude of the friction, but not the friction coefficient.
The amount of friction divided by the weight of an object forms a unitless number called the ... of friction?
coefficientThe amount of friction divided by the weight of an object forms a dimensionless number called the coefficient of friction.
What is the function of coefficient of static friction?
This coefficient of static friction is needed to find the frictional force between a body and a surface on which body has to move. If u (mu) is the coefficient of friction then uR gives the frictional force between moving body and surface. There is no unit for coefficient of friction. Here R is reaction which equals to the weight of the body
What does a coefficient of friction of 1.0 or greater mean?
It means that the maximum force of friction is greater than the weight of the object.
What factors can effect the amount of friction between two objects?
The force of friction between two objects is the product of the normal force and the coefficient of friction. The normal force is the component of force that is perpendicular to the plane of friction. For example, if you are pushing on a block of wood on the floor with a force F at an angle of 30 degrees above the horizontal, then the normal force N = F sin 30. The coefficient of friction is specific to the two materials, in this example the block of wood and the floor. In addition, there is a static coefficient of friction (applicable to a stationary situation) and a kinetic coefficient of friction (applicable when the object is already moving).
