Question

Payton was studying the effects of mass on the force of friction. He recorded his results in the table above.

Which of the following statements would be the most valid conclusion Payton could draw from his results?

A) When the mass of an object increases the force of friction decreases
B) When the mass of an object decreases the force of friction remains the same
C) When the mass of an object increases the force of friction increases
D) When the mass of an object decreases the force of friction increases

Answer 1

Obviously, by seeing the data , we can say that as the mass is increasing , the frictional force is increasing.

This is the true experiment that is done to find the Coefficient of friction


But now that we know Frictional force = Kinetic coefficient of friction*Normal force which is actually proportional to the mass of the body.

So , Option (C) is correct.

Answer 2

Answer:

$When the mass of an object increases the force of friction increases$

is the right answer
