Question
Which of the following forces does NOT have a zero work done on the object:
a)The normal force on a box that slides across a horizontal level floor.
b)The weight on a box that slides across a horizontal level floor.
c)The normal force on a box that slides down an inclined plane.
d)The weight on a box that slides down an inclined plane.
e)Actually all of the above describe forces that do zero work.
I think the answer is e) since all of them involve a force moving through a distance?
