Energy and Energy Transformations

Energy transformation is the process of changing energy from one form to another, such as converting chemical energy in batteries to electrical energy in a flashlight.

The main forms of energy include kinetic, potential, thermal, chemical, electrical, radiant, and nuclear energy.

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

The energy transformation is from chemical energy (in batteries) to electrical energy to radiant energy (light).

Chemical energy is NOT produced by a lamp; it primarily produces radiant (light) and thermal (heat) energy.

A fan transforms electrical energy into mechanical energy.

Chemical energy is stored in food.

Radiant energy is the energy of electromagnetic waves, including visible light, infrared, and ultraviolet radiation.

Mechanical energy is the sum of potential and kinetic energy in an object, enabling it to do work.

Thermal energy is the energy that comes from the temperature of matter, related to the motion of particles.
