Chapter 4 Section 1

  • Electricity

    Electricity

    Discovered by Benjamin Franklin (KITE)
  • The Joule

    The Joule

    The SI unit of work or energy, equal to the work done by a force of one newton when its point of application moves one meter in the direction of action of the force, equivalent to one 3600th of a watt-hour.
  • Thermal Energy

    Thermal Energy

    Discovered James Prescott Joule
  • Kinetic Energy

    Kinetic Energy

    Discovered by Gottfried Leibniz and Johann Bernoulli
  • Chemical

    Chemical

    Discovered by J. Willard Gibbs
  • Radiant

    Radiant

    Discovered by Nikola Tesla
  • Elastic Potential Energy

    Elastic Potential Energy

    Potential energy stored as a result of deformation of an elastic object, such as the stretching of a spring. It is equal to the work done to stretch the spring, which depends upon the spring constant k as well as the distance stretched.
  • Chemical Potential Energy

    Chemical Potential Energy

    Stored within the bonds of atoms and molecules of a substance. The bonds have stored chemical potential energy which is released when they are broken and the substance undergoes a chemical reaction.
  • Gravitational Potential Energy

    Gravitational Potential Energy

    Energy an object possesses because of its position in a gravitational field
  • Kinetic Energy Equation

    Kinetic Energy Equation

    K.E. = 1/2 v squared
