  2. Work is... the result of force moving an object.

  3. Force is... a push.

  4. Force is... a pull.

  5. Two Kinds of Energy • Potential • Kinetic

  6. Potential energy is... stored energy.

  7. Kinetic energy is... energy in motion.

  8. Energy can be… • electrical • mechanical • chemical

  9. Electrical energy is... a result of electricity.

  10. Mechanical energy is... the energy of moving objects.

  11. Chemical energy is... is stored in matter.

  12. When two objects rub or touch, there is... friction!

  13. Friction will... • slow down an object. • stop an object.

  14. When an object is still it tends to remain ... still.
