Question

How much work is done when a very large force is applied to an object but does not move the object?
a. none
b. a lot
c. a little
d. The exact amount of work and the weight of the object must be known to figure this out.

Answer 1

                         Work  =  (force) x (distance)

If the distance is zero (the object doesn't move), then it
doesn't matter how great the force is.  The work is still zero.
