Document Summary
Energy is never created nor destroyed; it"s transformed from one form to another: source: from the sun which generates its energy through gravitational sources by fusing hydrogen atoms and forming helium. Solar energy: we"re catching waves from the sun into electrical energy and same with wind energy: nuclear energy is done by nuclear fission. Aurora borealis: collisions between gaseous particles in earth"s atmosphere interact with charged particles released from sun"s atmosphere (creates the northern lights) Difference in contractile units within the muscle: the shorter the race, the faster you can run, the more power the muscle must generate. During the first few seconds you can generate and use lots of energy and run really fast (atp- Efficiency = work produced/free energy of atp = output/input = watts/vo2 = kcals/kcals. Efficiency: amount of energy released at a given point of time and how much work can be done with that energy.
