Which produces the greater change in kinetic energy (assume that all of the work goes into kinetic energy):
A) exerting a 10N force for a distance of 5m
B) exerting a force of 20N over a distance of 2m
C) exerting a 30N force for a distance of 1.5m
D) exerting a force of 40N over a distance of 1m

Question

Quizplus · Accepted Answer

The work done, which equals the change in kinetic energy, is calculated as force multiplied by distance. For option A, the work done is 10N * 5m = 50J, which is greater than the work done in the other options.
