Question

If you push a box across the floor, the box experiences what kind of friction?

Answer 1

I think it is kinetic friction not the best at physics

Answer 2

Answer:

For this situation the right answer is d, the kinetic friction, because in this case we are talking about moving surfaces: the surface of the box moving along the surface of the floor.

When this happens there may be a force that acts in opposite direction to the movement of the box and tends to stop it (Friction).

The other options are not correct because:

a) The cohesive friction does not exist

b) The Rolling Friction applies for a body that rolls on a surface (an object with the shape of a circumference for example), and in this case the situation described is with a box

c) Static Friction is the friction in a body that keeps at rest. In this situation is not applied because the body is in motion

d) Potencial friction does not exist
