1. The magnitude of the force of the kinetic friction depends upon shape of surface in contact
2. The magnitude of the force of the kinetic friction depends upon apparent area of the surface in contact
3. Force of kinetic friction is independent of material of the surfaces in contact
4. The magnitude of the force of the kinetic friction is approximately independent of the relative velocity provided it is not too large or small
