Did you know…?The pedicar, introduced in 1973, was a pedal-powered, one-passenger, all weather vehicle. It was conceived as an alternative to the gas-powered automobile and cost about $550. It could reach 15 mph.

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.
