  1. Energy Review & Continuation

  2. Forms of Energy • Potential • Chemical • Gravitational • Nuclear • Mechanical • Kinetic • Motion • Sound • Thermal • Radiant • Electrical

  3. Formulas • F=ma • W=Fd <<or>> W=mad • P=W/t <<or>> P=mad/t • PE=mgh • KE=1/2mv2

  4. An Example Mass= 10 kg Gravity=9.8m/s/s Height= 1 m PE=mgh PE=(10)(9.8)(1) PE=98 Joules

  5. An Example Mass= 10 kg Gravity=9.8m/s/s Height= 0.5m PE=mgh PE=(10)(9.8)(0.5) PE=49 Joules

  6. Conservation of Energy • 1st Law of Thermodynamics • Energy cannot be created or destroyed • If the distance changed from 1m to 0.5m, the amount of PE decreased from 98 to 49 • Where did the energy go? • It was converted from PE to KE!
