    Study Notes

    Types of Energy

    • Sound Energy: Energy travels as waves through matter. It's kinetic energy.

    • Electrical Energy: Energy from moving electrons. It's kinetic energy.

    • Nuclear Energy: Potential energy stored within atomic nuclei, released through fission or fusion.

    • Mechanical Energy: The sum of potential and kinetic energy within an object or system. It remains constant.

    • Chemical Energy: Energy stored in the bonds between atoms and molecules.

    • Radiant Energy: Energy from light waves. It's kinetic energy. Examples include solar energy.

    • Thermal Energy: Energy from heat. It's kinetic energy.

    • Potential Energy: Stored energy. Gravitational potential energy is highest when an object is highest above the ground.

    • Kinetic Energy: Energy of motion. Highest when an object is moving the fastest.

    • Law of Conservation of Energy: Energy cannot be created or destroyed, only transformed from one form to another.

    • Energy Transfer: Energy changes from one form to another. Heat is often a byproduct of this change.

    • Electromagnetic Energy: Energy traveling through space as waves, including radio and satellite waves.
