    Work - Product of the force and distance moved in the direction of the force

    Energy - The quantity which represents the ability to perform work whose SI unit is joules
    Types of Energy - Chemical, mechanical, heat, electrical, radiant, kinetic, potential
    Chemical Energy - The potential of a chemical substance to undergo a transformation through a chemical reaction to form another substance. The breaking or making of chemical bonds involves absorbing or giving off energy
    Mechanical Energy - The sum of potential and kinetic energy in a mechanical system which is associated with the motion or position of an object
    Heat Energy - Energy transferred from one body or system to another due to thermal contact when the systems have different temperatures
    Electrical Energy - Is the amount of total work that can be done within an electrical system
    Radiant Energy - The energy of electromagnetic waves (light)
    Kinetic Energy - Energy possessed by a body due to its motion (ex. moving ball)
    Potential Energy - Energy possessed by a body due to its position or state (ex. fruit in a tree)
    Law of Conservation of Energy - Energy cannot be created or destroyed
    Energy transformation examples -
    Bullet fired from a gun - Chemical energy from the gun powder is converted into heat energy and then mechanical energy
    Battery used to light a bulb torch - Chemical energy in the battery is converted to electrical energy, then heat energy heats the filament and light energy is emitted from the bulb

    Power - Work done per unit time
