Bungy jump

When you Bungay jump on got to make sure your gear is n properly so you don't brake your legs
When you the clif gravity pulls you down and potential energy is stored in the robber band.
When you do Bungay jumping only one person goes at a time so you don't get hurt.
Elasticity means how stretchy the cord  is . Rigidity  means how strong the cord is.
