Heat is a form of energy, since it will expand steam that will force wheels into motion that can then do work. HEAT IS A FORM OF ENERGY SINCE IT WILL EXPAND STEAM THAT WILL FORCE WHEELS INTO MOTION THAT CAN THEN DO WORK
lf, that was the beginning of the actinium radioactive series. As for thorium (atomic symbol Th) with an atomic weight of 232, it did indeed turn out that in the naturally occurring element virtually all the atoms were ²³²Th. ENERGY The Law of Conservation of Energy We have now gone as far as we conveniently can in considering the intertwining strands of the atom and of electricity. It is time to turn to the third strand—energy. To physicists the concept of “work” is that of exerting a force on a body and making it move through some distance. To lift a weight against the pull of gravity is work. To drive a nail into wood against the friction of its fibers is work. Anything capable of performing work is said to possess “energy” from Greek words meaning “work within”. There are various forms of energy. Any moving mass possesses energy by virtue of its motion. That is, a moving hammer will drive a nail into wood, while the same hammer held motionlessly against the nailhead will not do so.
