Question

For work to be done on the object, the object has to ____________________.

Answer 1

Move? Change position?

Answer 2

It depends upon what you mean by work. If work is defined as Force x Distance, which it commonly and correctly is, the object must actually move in the direction of the force.

Batteries, however, can also be said to do work, and whilst it is true that electrons are actually moving very slowly around a closed circuit, it is not really the same thing.

You will also expend energy trying to lift a Jumbo Jet even if you are locked in a totally static position and, obviously, with the plane not budging. So, you are still getting a work out even though there is no motion.

Answer 3

They should really word the questions better, eh? Thanks, good answer. I'll go with the force/distance work.
