Question #fc136

Answer 1

`W=Fd`
(Work = force × distance)

a) Using more force to move an object results in a greater value for `F`, which would mean more work was done

b) You lift a 20 N object faster - speed has nothing to do with work; you do the same amount of work lifting an object quickly vs. lifting it slowly

c) You raise an object a shorter height - a shorter height means that there is a smaller distance, so less work would be done

d) You move a lighter object - it depends on the force you exert on the object. If you used the same amount of force that you did with a heavy object, you are doing the same amount of work.

e) You move an object farther - there would be a greater value for `d`, so you'd be doing more work
