Question

Consider the acceleration graph. If the mass of the object that is accelerating does not change, but the force applied is tripled, how would the slope of the line change?

A) The slope of the line would be zero.
B) The slope of the line would increase.
C) The slope of the line would decrease.
D) The slope of the line would remain constant.

Answer 1

the correct answer is B)the slope of the line would increase 

Answer 2

I assume that the "acceleration graph" is a graph of the force versus the mass.

In such a graph, the acceleration is equal to the slope of the line, given Newton's second law:

`F=ma`
we can see that there is a direct proportionality between F and a. So, when we triple the force, if the mass remains constant, then the acceleration will also triple, and so the slope of the line increases.

Therefore, the correct answer is:
B) The slope of the line would increase.
