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.

About forces and movement .

The main forces used in the game are potential energy and kinetic energy 
The bird fulys then gravity pulls it down action ans reacotion is when
The bird Hirts the piggies die .

Rocket Energy


Purpose: we are trying to figure out where the potential  engy we pull the Roband back and let it go it flys in the air

Materials:the materials was a plastic rocket and a Handel tied with a Roband on it

Method:we put the rocket on the robber band then we pulled the robber band  back and we released the rocket to fly

Observations: when the rocket started to fly up in the air it came down 

Conclusion: from this experiment where this energy is coming from it is first potrtenteil energy it's power comes from us pulling the robber band  the energy turns into kinetic baceuse it was
Going to the rocket when we release the robber band the power is on the rocket for it to fly
