  1. Energy

  2. What types of energy are there?

  3. What types of energy are there? • Nuclear • Fusion • these we have talked about • Fission • Mechanical (Kinetic) • Potential • Gravity • Springs • Chemical • Light • Heat • Electrical

  4. Kinetic and Potential Energy • From our study of Friction, what might kinetic energy mean? • Energy of motion • Large objects (meteors) • Small objects (bullets, raindrops, marbles) • Tiny objects (molecules, atoms) • http://www.middleschoolchemistry.com/multimedia/chapter1/lesson2 • What variables might be in an equation to calculate kinetic energy? • Mass, speed • KE = ½ mv2

  7. Kinetic and Potential Energy • What might potential energy mean? • Examples • An object at the edge of a cliff • A mass on a spring • A stretched rubber band • A can of gasoline (chemical potential energy) • What do we have left when all of the potential energy is used up?

  8. Kinetic and Potential Energy • What might potential energy mean? • Examples • An object at the edge of a cliff • A mass on a spring • A stretched rubber band • A can of gasoline (chemical potential energy)

  9. Kinetic and Potential Energy • What might potential energy mean? • Examples • An object at the edge of a cliff • Mass, height, gravity • A mass on a spring • Stretch length, spring strength • A stretched rubber band • Stretch length, spring strength • A can of gasoline (chemical potential energy) • Volume, octane rating?

  10. Potential Energy • An object at the edge of a cliff • Mass, height, gravity • PE = mgh • Where m is mass in kg (cm) • g is 9.81m/sec2 (981 cm/sec2) • h is the height in meters (cm)

  11. h Gravitational Potential Energy Gravitational Potential Energy PE = mgΔh

  12. How could we measure the effect of potential energy? - Given a bunch of marbles or steel balls

  13. Tomorrow we will run an experiment to measure the effect of Potential Energy - By dropping them into flour and looking at the craters

  14. Andy Saulietis Craters are everywhere! LPL / UA The Moon Apollo 17 NASA
