Answer: Friction
Explanation:
Friction is a force that opposes the motion of an object on another surface. For example, when a box is pushed along the floor, the floor exerts a frictional force on the box, "resisting" the motion of the box. This force is due to the contact between the molecules of the box and the molecules of the floor, and it is always directed against the direction of motion of the object (so, if the object is moving forward, friction acts backwards).
The magnitude of the friction force is given by:
![F=\mu N](https://tex.z-dn.net/?f=F%3D%5Cmu%20N)
where
is the coefficient friction, which is a number that depends on the materials of the two surfaces, and N is the normal reaction.
