does a piece of wood have energy?

Hi Gillian,

To answer this question, think about what happens when you burn wood: the wood gives off heat and light. It takes energy to give off light and heat, so the wood must have had some energy to begin with, or at least the wood and the air together do.

The kind of energy the wood has to begin with is called chemical energy because it can be released through a chemical process like burning. However, chemical energy is only one kind of energy that a piece of wood might have. For example, if you threw a piece of wood it would have kinetic energy, which is what the energy of moving objects is called.
