Question
what is impossible for a machine to do?
do a greater amount of work than the amount of work done on the machine
apply a force in a direction that is different than the direction of the force applied to the machine
move an object a greater distance than the distance that part of the machine was moved
apply a force that is less than the force that is applied to the machine
According to the law of conservation of energy, a machine cannot do more work than the work inputted into it. Machines can change the direction of force, move objects over different distances relative to the movement of their parts, and apply forces different from the input force in magnitude and direction. But the total work output cannot exceed the work input.
