The graphs above show the magnitude F of a force exerted on an object as a function of the object’s position x for two trials in an experiment. W1 and W2 are the work done on the object by force 1 and force 2, respectively. How do W1 and W2 compare, and why? A) W1 > W2 , because the slope of force 1’s graph increases, while the slope of force 2’s graph decreases. B)W1 < W2 , because the average value of force 1 is smaller than the average value of force 2. C)W1 < W2 , because at the midpoint, x = 0.5 m , the value of force 1 is less than the value of force 2. D)W1 > W2 , because the maximum value of force 1 is greater than the maximum value of force 2.
