Energy Glossary

Energy associated with chemical substances.

a fundamental law in physics that states that energy cannot be created or destroyed; it can only be transformed from one form to another. It's like the universal accountant that keeps track of every energy transaction, ensuring that the cosmic books remain balanced.

The principle that energy cannot be created or destroyed.

the change in position of an object in a particular direction.

energy transferred into less useful stores, often thermal stores of the surroundings.

The spreading of energy into the surroundings, usually into internal energy stores.

the ratio of useful output or work done to the total input or energy expended. It's like the yardstick that measures how effectively we utilize our resources and get the most bang for our buck.

Energy stored when an object is stretched or compressed.

the energy stored in an elastic object, such as a stretched or compressed spring, when it is deformed from its equilibrium position. It's like the hidden energy waiting to be released, as if the object is eagerly anticipating its chance to bounce back.
