  • Chartist movement: A movement of working class people who wanted to reform the government and improve their lives
  • Who founded the chartist movement?
    William Lovett and Francis Place
  • What did the chartists want?
    Political reform and democratic rights for working-class people in the 19th century.
  • Closed System: A system that experiences no net change in its total energy when energy transfers occur within it
  • Conservation of Energy: The law that energy can be transferred, stored or dissipated but never created or destroyed
  • Efficiency: The ratio of useful output energy transfer to total energy input
  • Elastic Potential Energy: The store of energy that stretched or compressed objects experience
  • Elastic Potential Energy is directly proportional to the stiffness constant and to the square of the extension or compression
  • Fossil Fuels: Coal, oil and gas
  • Gravitational Potential Energy: The store of energy that all raised matter has
  • Gravitational Potential Energy is directly proportional to the mass of the object, the distance that it is risen and the gravitational field strength at that point
  • Joule: The unit used for energy
  • Joule is equal to the work done when a force of one Newton acts over a distance of one metre
  • Kinetic Energy: The store of energy that all moving matter has
  • Kinetic Energy is directly proportional to the object’s mass and to the square of its velocity
  • Power: The rate at which energy is transferred, or at which work is done
  • Renewable Energy Resource: An energy resource that can be replenished whilst it is being used
  • Spring Constant: A measure of a spring’s stiffness
  • The greater the value, the greater the force required to stretch or compress the spring by a given distance
