Ethan pushes a wooden box across a carpeted floor.Then he pushes the same box across a smooth marble floor.Why does Ethan find it easier to push the box on the marble floor than on the carpeted floor?

The carpeted floor has a rough surface and hence produce greater friction while the marble floor is smoother thus generating a smaller friction.

Answer:

The smooth marble floor has lower friction coefficient

Explanation:

Remember that when you are pushing any object theres a force pulling on the opposite direction to you, that is the friction force, which is given by the next formula:

[tex]Friction force: (coefficient of friction)(Weight of the object)[/tex]

SInce he is pushing the same exact box, with the same exact weight, the only reason to find it easier is that the marble floor has a lower coefficietn friction, and for that reason he has less friction force working against him.
