Energy interacts with matter in ways that produce observable effects like light, heat, movement, and sound. Three common interactions taught in elementary classrooms are electricity, magnetism, and sound.
1. Electricity
Electricity is a fundamental form of energy resulting from the movement of electrons, which are negatively charged particles that orbit the nucleus of an atom. It plays a major role in both natural systems (like lightning) and man-made technologies (like household circuits).
Types of Electricity
- Static Electricity
Occurs when electrons accumulate on the surface of an object and do not flow continuously.
This buildup can result from friction between two materials, such as rubbing a balloon on your hair or shuffling across a carpet.
When the stored electrons finally discharge, it causes a spark or a small shock.
