2. Different Forms of Energy
The Nature of Energy
Different Forms of Energy
Electromagnetic energy from the Sun travels a vast distance through
space to Earth, warming the planet and providing energy that enables green plants to grow.

3. Types of Energy
Radiant Energy is a type of electromagnetic energy which is energy that travels in waves such as light.
Chemical energy is energy that is stored in chemical bonds
Mechanical energy is energy associated with the motion or position of an object
Thermal energy is the total energy of all particles in an object

4. Types of Energy
Electrical energy is the energy of moving electrical charges.
Nuclear energy is energy stored in the core, or nucleus of an atom.
Gravitational Potential energy is energy that depends on height.
Elastic Potential energy is the energy in something that can be stretched.

5. Kinds of Energy
Each of the types of energy listed before fall into two different kinds of energy, potential and kinetic.
Potential energy is stored energy waiting to be used.
Kinetic energy is energy of motion.
