Conclusion Answer

Machines transfer energy from one object to

another to make work easier. For example,

when you use a crowbar to remove a

hubcap, you transfer energy to the crowbar

and the crowbar transfers energy to the

hubcap. The way the energy is transferred

determines how much easier the work is to

do.
