There are different kinds of energy
Movement energy – when a body is in motion, for instance, a train traveling down the tracks.
Elastic energy – contraction of bending of an object, for instance, pushing or pulling a spring.
Height energy – stored in an object which is raised from the earth and which is used as the object falls, for instance, a waterfall.
Electric energy – passing a flow through a conductive material, turning on an electrical device.
Sound energy – making a noise, vibrations moving through a substance, for instance, sounds coming from a speaker.
Chemical energy – when a material undergoes a chemical change, for instance, gas combustion, burning wood, using gas for cooking, and more.
Energy changes its shape and shifts from one form of energy to another. Thanks to this conversion of energy, human beings can take advantage of energy for all of our needs as well.
Energy stored up in our muscles is converted to mechanical energy at a frequency which can vibrate rods (a resonant device), to rotational mechanical energy in a hamster wheel, barrel walking, or through the pedals of a bike.
These are all just a few ways that energy can be converted into sound, movement, and light.
