  1. Conservation of Energy (E)

  2. Energy (E) means Total Energy Conservation of Energy (E)

  3. Drop a Ball off a Cliff

  4. Drop a Ball off a Cliff When is the ball moving the fastest? at the lowest point * * just before it hits the grounds and just after

  5. Drop a Ball off a Cliff When is the ball moving the fastest? at the lowest point * When is the ball moving the slowest? at the highest point (it has to stop in order to change directions)

  6. Drop a Ball off a Cliff When is the ball moving the fastest? at the lowest point * When is the ball moving the slowest? at the highest point What is the ball trading for speed? height
