What are the factors that determine the friction force between two sliding objects?
The normal force between the two objects and the coefficient of friction. Force of friction = normal force x 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 are the factors that determine the amount of friction between two surfaces?
Friction= Normal force* Coefficient of friction
What is the coefficient of friction between a perfectly smooth body and a very rough body?
The coefficient of friction depends on the type of materials. Different pairs of materials have different cofficients of friction.
On a flat surface the coefficient of friction is a ratio between and the weight of the object?
The force of friction!
A block accelerates at 3.2 down a plane inclined at an angle 30 degrees. Acceleration of gravity is 9.8. Whats the coefficient of static friction between the block and the inclined plane?
Static friction does not apply when the block is already moving. Without friction, the force on the block parallel to the surface of the incline is Fg*sin(angle), so the acceleration without friction is 9.8* sin(30) = 9.8 * (1/2) = 4.9 Since it is accelerating at 3.2, friction is slowing down the block by (4.9-3.2 = 1.7). The coefficient of kinetic friction is (1.7/4.9) = 0.346939
Is the coefficient of friction on a horizontal plane between to substances the same as the coefficient of friction on the incline plane?

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 are the factors that determine the friction force between two sliding objects?
The normal force between the two objects and the coefficient of friction. Force of friction = normal force x coefficient of friction.
What is the coefficient of friction between a playground slide and a child if the child accelerates down the slide at 1.16 meters per second squared and the slide is inclined 31 degrees?

What is the coefficient of friction for talcum powder.?
The coefficient of friction is defined as being between two substances, not just one substance.
What is the function of coefficient of static friction?
