BSL Physics Glossary - energy change, energy transfer - definition

Energy can change from one form to another. For example chemical energy might change to heat energy. Light energy can change to chemical energy. For example in the garden there are plants and flowers growing. Light energy from the sun lands on the leaf. Inside the leaf a chemical change happens. It is this chemical energy which helps the plant grow.

Remember we don't make or destroy energy. The energy may be changed into different sorts, but it is not lost or made.
