10. Kinetic energy: It’s the energy an object has due to motion Example: A moving bowling ball has energy that causes the pins to fall . This energy is called kinetic energy. Kinetic Energy
11. The sky diver has kinetic energy A ball kicked by a football player has a kinetic energy
12.
13. Imagine those two rocks are rolling down the hillside with the same speed. Which one will have more kinetic energy? Which one will cause more damage if they hit something at the bottom? The larger rock could cause more damage because it has larger mass and has more kinetic energy than the smaller rock
14. Kinetic energy also depends on speed . The faster object has more speed and has more kinetic energy

17. This skater has no kinetic energy as she’s standing at the top of the hill and not moving . As the skater moves down , she is moving faster and her kinetic energy increases. Remember: Energy can not be created nor destroyed, so where does this kinetic energy come from?
22. When you throw a ball upwards it is moving the fastest so it has maximum kinetic energy As the ball moves upward , it slows down and stops for an instant As the ball moves downward it speeds up and the potential energy is transferred into kinetic energy
26. Water at the top of the dam has potential energy. When water falls downwards the potential energy changes into kinetic energy The kinetic energy in the moving water spins the generators and that’ll produce electrical energy
27. Law of conservation of energy “ Energy cannot be created or destroyed it only can be transformed from one form into another”
28. So, The total amount of energy never changes , it only changes form
