Coefficient of friction byjus
WebCoefficient of friction between 5 kg and 10 kg block is 0.5. If friction between them is 20 N, the value of force being applied on 5 kg (in N) is (Assume that the floor is frictionless) Solution The limiting friction between 5 kg and 10 kg is fl2 =50×0.5 =25N. Since 20< 25, the two blocks are moving with a common acceleration. WebFeb 1, 2024 · The coefficient of kinetic friction is the force between two objects when one object is moving, or if two objects are moving against one another. The coefficient of friction is dimensionless, meaning it does not have any units. It is a scalar, meaning the direction of the force does not affect the physical quantity. read less
