Question

5. The graphs above show the magnitude F of a force exerted on an object as a function of the object's position xfor two trials in an experiment. W, and W, are the work done on the object by force 1 and force 2, respectively.How do w, and W2 compare, and why?(A) W, > W2, because the maximum value of force 1 is greater than the maximum value of force 2.(B) W, > Wą, because the slope of force 1's graph increases, while the slope of force 2's graph decreases.(C) W,

Answer 1

We are given the graphs of two forces F1 and F2.

Notice that the graph of force 1 is increasing whereas the graph of the force 2 is decreasing.

This means that the slope of force 1 is increasing and the slope of force 2 is decreasing.

So, the work done by force 1 is greater than the work done by force 2.

Therefore, the correct answer is option B.

W1 > W2, because the slope of force 1's graph increases, while the slope of force 2's graph decreases.
