passage: Mechanical energy is a combination of the energy of motion or position .
  This type of energy describes objects that are moving or could move .
  A moving ball can have energy from motion .
  An arrow can also have the energy of motion .
  Both are types of mechanical energy .
  Can you think of some other examples ?
  Where does the energy of motion come from ?
  It comes from the energy created by position .
  This energy is stored energy .
  This means it is not moving yet , but it has the potential to move .
  How can you store energy ?
  The arrow gains energy from the drawn bow .
  As the arrow is released , the bow releases its stored energy and puts the arrow into motion .
  Can you think of some other ways to store energy using position ?
query_and_answer: Why is it possible for a moving ball to still have energy of position ? || Because it has weight
evidences: Mechanical energy is a combination of the energy of motion or position . This type of energy describes objects that are moving or could move .
