Friction. Kinetic friction, to be precise.
Frictional Force.
friction
kinetic frictionA second opinion:Kinetic friction is the resistance to sliding motion when they're already moving.The beginning of sliding motion is resisted by static friction.
Friction
Friction is caused when two surfaces come into contact with one another. The irregularities on the surfaces rub against one another and friction results. Friction opposes motion. That is to say, friction acts in the direction opposite to motion.
The force that opposes relative motion btwn two surfaces in contact with each other
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.

Friction
the force that opposes the motion of two touching surfaces is velocity.

Sliding Friction If you push hard enough on the cardboard box filled with books, it will start sliding. If you stop pushing after the box starts sliding, it will slow down and stop. The force that acted on the box to slow it down was sliding friction. Sliding friction is the force that opposes the motion of two sliding surfaces in contact. Sliding friction exists between all sliding surfaces that are touching, such as the surfaces of the moving parts in a car's engine.
Friction. Static friction is more precise.
FRICTION .......... friction
The force is called friction.
it is because of friction. friction is a force that opposes the relative motion of two surfaces in contact.
