Luke observed that it is harder to push a heavy box across a carpeted floor than a tiled floor. This is because __________.

A the tiled floor is smoother and has less friction
B the box has more mass on the carpeted floor
C the carpeted floor is smoother and has more friction
D gravity acts more strongly on the tiled floor

Worked Solution

Step 1: Friction depends on the types of surfaces in contact. Step [2-9]: Carpet is a rougher surface than tile. Step [2-9]: Rougher surfaces produce more frictional force, making it harder to move the box.

Correct answer: the tiled floor is smoother and has less friction
