Physicists classify energy into three major types
including kinetic (dynamic or energy on the move), potential
(static or energy at rest) and radian (electromagnetic). There are
many ways to generate energy including
chemical, mechanic, light, electricity, magnetism, heat, nuclear, and sound. However, many other
items can be considered as "energy".
The "Law of Conservation of Matter and
Energy" states that energy can only change forms, it cannot be
destroyed. So a toaster changes electrical energy into heat or a
television changes electrical energy into light and sound.
This activity concentrates
on energy at rest (potential) and energy on the move (kinetic).
Potential energy can change into kinetic energy to create work.
You can pick up a book and this is potential, let it go and it is
words seem difficult, but students love to say them because they can
then describe energy.
