This can be helpful when comparing your present wage to a wage being offered by a prospective employer where each wage is stated in a different periodic term (e.g., one is listed as an hourly wage and the other is listed as annually).
Definition Of Work. Work is the transfer of energy. In physics we say that work is done on an object when you transfer energy to that object. If you put energy into an object, then you do work on that object (mass).If a first object is the agent that gives energy to a second object, then the first object does work on the second object.The energy goes from the first object into the second object.f you put energy into an object, then you do work on that object (mass). If a first object is the agent that gives energy to a second object, then the first object does work on the second object. The energy goes from the first object into the second object.
When electrons gain or lose energy, they jump between energy levels as they are rotating around the nucleus. For example, as electrons gain energy, they might move from the second to the third level. Then, as they lose energy, they might move back to the second level or even to the first energy level. Only a certain number of electrons can be in an energy level at the same time. The photon shown in the graphic can be considered a small bundle of energy. (For more information on atoms, you may want to review the materials on magnetism.) Review: Electrons spin and rotate around the outside of the nucleus.
