What causes a sinkhole and why are they common in Florida?
Acids in groundwater weaken the rock causing it to eventually collapse. It's common in Florida because of the large amount of soft limestone in the ground.

Explain the energy transformation that occurs when a slingshot is released.
Elastic Potential Energy is turned into Kinetic Energy and then, at its peak height, turns into Gravitational Potential Energy and then finally it transforms back to Kinetic Energy as it falls to the ground.
