7 Electromagnetic Energy Energy traveling in the form of wavesX-rays Visible light
8 Nuclear Energy Energy stored in nucleus of an atom Nuclear Power plants convert nuclear energy to electricity
9 Energy conversions Law of conservation of energy: Energy cannot be created or destroyed, only converted from one form to another
10 Impact crater in Arizona formed within past 20 yrs Large KE of meteor converted to large amountof thermal energy vaporizing everything inClose proximity
11 Energy conversionsLight bulb : converts electrical into thermal and electromagnetic energyCompressed Spring: converts potential to kineticBurning wood: stored chemical energy converted to thermal and electromagnetic
12 If friction is ignored total mechanical energy will remain constant Energy Conversionin a PendulumIf friction is ignored total mechanical energy will remain constant(KE + PE) start = (KE + PE)endPendulum would swing forever!!!
