Friction is a force that opposes the motion of any object moving on it.

Friction is like a force that happens when two things rub against each other and resist moving. It's the reason it can feel hard to push a heavy box across the floor or why sliding down a slide is slower than falling straight down.
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 a force that resists the relative motion or tendency of motion between two surfaces in contact. It arises from the interactions between molecules on the surfaces and can affect the movement of objects.
