Friction is a force that opposes the motion of any object moving on it.
Sliding friction is the resistance encountered when one object slides over another. It occurs when two surfaces are in contact and sliding past each other, causing heat and energy loss.
The 3 types of friction are static friction (force between stationary objects), kinetic friction (force between moving objects), and rolling friction (force between a rolling object and a surface). Friction is the resistance that one surface or object encounters when moving over another.
Fluid friction is the resistance experienced by an object moving through a fluid, such as air or water. Sliding friction is the resistance encountered when two surfaces slide past each other. Both types of friction contribute to the overall force opposing the motion of an object.
Stationary friction refers to the resistance between two surfaces in contact with each other when there is no relative movement between them. It is the force required to overcome the static friction and set an object in motion.
Friction is the force that opposes the relative motion or tendency of such motion of two surfaces in contact. An illustration of friction can be seen when trying to slide a heavy box across a rough surface - the resistance you feel while trying to move it is due to the friction between the box and the floor.
