Which two of the following are forms of kinetic energy?

• Thermal: vibrating atoms in substances. Faster movement = higher heat

• Elastic: stored in objects that are stretched or squashed beyond normal

• Electric: moving electric charges called electrons

• Gravitational: stored in objects that are held a distance away from the Earth

Which of the following is chemical energy?

• Stored in the bonds between atoms.

• Stored inside the nucleus of an atom.

• Vibrating particles rub against each other.
