    Study Notes

    Energy Fundamentals

    • Energy is defined as the ability or capacity to do work.

    Thermal Energy

    • The unit of thermal energy is the joule (J).

    Temperature

    • Temperature is a measurement of the average kinetic energy of particles in a substance.

    Energy Forms

    • Vibrational energy is associated with the vibration or disturbance of matter.

    Gravitational Potential Energy

    • Energy stored by objects that are above Earth's surface is called gravitational potential energy.

    Law of Conservation of Energy

    • The law of conservation of energy states that energy cannot be created or destroyed, only converted from one form to another.

    Radiant Energy

    • Radiant energy from the sun is a form of electromagnetic radiation, including light and heat.

    Nuclear Energy

    • Energy released from the fusion or fission of the nucleus of an atom is called nuclear energy.

    Elastic Potential Energy

    • The energy stored by something that can stretch or compress is called elastic potential energy.

    Energy Conservation Principle

    • The energy of a system and its surroundings are interconnected, with energy being converted from one to the other.
    • A 'system' refers to a region where energy is being transformed or converted.
    • The 'surroundings' refer to everything outside the system that is affected by the energy transformations.
    • Energy can be converted from one form to another, but the total energy remains constant.
    • An example of energy conversion is in a power plant, where chemical energy is converted into electrical energy.
    • When an explosive detonates, chemical potential energy is converted into kinetic energy, heat, and light.
    • The total energy of the universe is constant, according to the principle of energy conservation.
    • The principle that states there is a fixed amount of energy in the universe is known as the law of conservation of energy.
    • In the context of energy conservation, energy is defined as the ability or capacity to do work.
