The two types of friction are static friction and kinetic friction. Static friction occurs when two surfaces are at rest relative to each other, while kinetic friction occurs when two surfaces are in motion relative to each other.
centrifuge, which is a kind of friction
The friction felt between two flat surfaces can either be sliding friction or static friction.
The friction is static friction.
Friction= Normal force* Coefficient of friction
Friction produces mechanical energy, which is the energy associated with the motion and position of an object. It transforms kinetic energy into heat energy due to the resistance created when two surfaces rub against each other.
Static
The coefficient of friction is a unitless value because it represents a ratio of the force required to move an object over a surface to the weight of the object. Since it is a ratio of two forces, it does not have any units associated with it.
