Relative motion is the concept that the motion of all objects is relative to other objects. If you are sitting still right now you are not moving relative to the earth, however you are moving relative to sun.
Friction opposes the relative motion of surfaces in contact. It acts in the direction opposite to the direction of motion or tendency of motion between two surfaces.
Friction is a force that resists the relative motion between two objects (which may be solids or fluids). Metaphorically, it is a situation in which actions by individuals can cause conflict between them.
The word you're looking for is "kinetic energy."
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.
The statement "rest and motion are relative terms" means that whether an object is considered at rest or in motion depends on the observer's frame of reference. For example, a person sitting on a bus is at rest relative to the bus, but in motion relative to a person standing on the street. This illustrates that rest and motion are relative concepts.

Tribology is the looking at interacting surfaces in relative motion and trying to engineer them. It looks at how wear, lubrication and friction impact how objects act with each other.

At rest and in motion are relative terms. When we say 'in motion' or 'at rest' we mean relative to something else. If you were travelling in a car for instance, you would be at rest relative to the car but in motion relative to the outside world.

Aristotle states that time is the measurement of motion, and motion is the reduction (change) of a being from a state of potency to a state of actuality by means of a being in act relative to the other being.
