1. chemical reactions happen in your brain creates impulses that makes you jump
2. mechanical energy is converted to kenetic energy and breaks the vase upon impact
3. an archer adds potential energy to the arrow and releases that energy to kenetic energy
4. potential energy builds up as you stretch the rubber band, when the bands slipped from your thumb it converts to kenetic energy
5. the ball has kenetic energy and due to its elasticity, it maintains it's energy and reflects it thus resulting to a bounce
