Cards (13)

  • System
    an object or group of objects
  • Energy
    a measure of the capacity of a body or system to do work
  • Kinetic energy
    the energy of motion of an object, equal to the work it would do if brought to rest
  • Gravitational potential energy (GPE)

    the energy gained by raising an object above ground level (due to the force of gravity)
  • Elastic energy
    the energy stored in a stretched / compressed elastic object, like a spring
  • Internal energy
    the sum of the energy of all the particles that make up a system, i.e. the total kinetic and potential energy of all the particles added together
  • Specific heat capacity
    the amount of energy required to raise the temperature of one kilogram of substance by one degree Celsius
  • Reproducible
    results are reproducible if the investigation / experiment can be repeated by another person, or by using different equipment / techniques, and the same results are obtained, demonstrating that the results are reliable
  • Transferred
    refers to how energy is changed, e.g. chemical energy can be transferred to electric energy
  • Dissipated
    wasted, scattered or spread out (to the surroundings)
  • Conductivity
    a measure of the ability of a substance to conduct electricity
  • Anomalous
    a data value that is significantly above or below the expected value / outside a pattern or trend
  • Renewable
    can be replaced
