The Law of Conservation of Energy states that energy may neither be created nor destroyed. How can this law be applicable to real life?

Consider a bowling ball hanging from the ceiling by a string. You are going to grab the bowling ball and bring it back to the wall with you. You put the bowling ball right in front of your face and release it so it swings forward. You do not move and allow the bowling ball to swing back towards you.

Creative Applications

  1. Will the bowling ball come back and hit you?
  2. Did the bowling ball swing back to your exact location? 
  3. What would have happened if you had leaned forward?
  4. Would the same thing happen with a different sized object?
