The force of friction always opposes the applied force. In the above activity, the force of friction acts between the surface of the book and the surface of the table. Is the friction the same for all the surfaces? Does it depend on the smoothness of the surfaces? Let us find out. 12.2 Factors affecting Friction. Activity 12.2.
12 Friction. 1. Whenever the surfaces in contact tend to move or move with respect to each other, the force of friction comes into play. (a) only if the objects are solid. (b) only if one of the two objects is liquid. (c) only if one of the two objects is gaseous. 2.
Friction is the hindering force that comes into play when two items are interacting with each other. Friction formula is typically given as. F f = μF n. The numeric’s are, the magnitude of friction is F f , the coefficient of friction is μ and the magnitude of the normal force is F n. The Normal force is equivalent to the weight of the given body.
Friction is the force that resists the motion of two surfaces moving past one another. What Causes Friction? Friction is caused by intermolecular (IM) attractions between particles of the two adjoining surfaces. Two Types of Friction. 1. Static Friction (Ffrict-static)
Friction is defined as the resistance offered by the surfaces that are in contact when they move past each other. Friction provides traction that is needed to walk without slipping. Friction is helpful in most cases. However, they also offer a great measure of opposition to the motion.

Friction is force acting between two surfaces in contact and it tends to oppose the motion of one surface over the other. Basically, friction is due to the interlocking of tiny projections on the surfaces as they are in contact.
