Question

A student rolls a marble on two different surfaces with the same force. The table shows the distance travelled in each trial.

Why does the marble travel a greater distance on glossy paper but not on sandpaper?

a) Because the mass of the marble on sandpaper is high.
b) Because the mass of the marble on glossy paper is high.
c) Because interlocking between the surface of marble and sandpaper is high.
d) Because interlocking between the surface of marble and glossy paper is high.

Answer 1

The answer is c that’s the answer

Answer 2

Option C, because interlocking between the surface of the marble and sandpaper is high.

Step-by-step explanation:

The distance an object travels relies on the force, mass, and friction imposed on the thing. Since the force and mass is constant, friction is the only variable that changes.

Rougher surfaces, such as sandpaper, have little bumps and grooves that increase the amount of kinetic (motion-related) friction an object can have, thus decreasing the distance as the more significant the friction, the more force an object needs to move the same distance.

Since mass is constant, A and B are eliminated. Glossy paper has a smooth surface, so interlocking is minimal; therefore, Option D can also be eliminated.

That leaves Option C.
