The coefficient of static friction between contact surfaces of two bodies is 0.5. The contact surfaces of one body support the other till the inclination is less than(Approximately).The rubbing produces friction and the result is heat. When oil is added to a car engine, the oil sticks to surfaces, and helps to decrease the amount of friction and wear on the parts of the engine. An engine that runs hotter requires a more viscous oil in order for it to stick to the surfaces properly. Measuring Friction K is the frictional force between the wooden block and the aluminum track, n is the normal force at the block-track interface, and m K is the constant coefﬁcient of kinetic friction between the block and the aluminum track. Remember that m K is a dimensionless quantity; it has no units. It is easier to achieve constant velocity at higher normal forces. Friction is the force that opposes the relative motion or tendency of such motion of two surfaces in contact. It is also the contact of two objects creating static electricity. It is not, however, a fundamental force, as it originates from the electromagnetic forces and exchange force between atoms.Mar 14, 2014 · The block slides on a frictionless horizontal surface, as shown.

friction, which resists the block’s motion down the plane due to the interactions between molecules of the block and plane. Since the sum of the forces in the x-direction must equal zero, then the force due to friction, Ff, must be equal to the component of the block’s weight that acts in the x-direction, or: Ff = mg (sin θ) (eq. 2) y x θ
