  • Physics Unit 1
    • Types of Energy
      • Kinetic
      • Thermal
      • Gravitational Potential
      • Light
      • Sound
      • Elastic Potential
      • Nuclear
      • Chemical
      • Electrical
    • Effieciency
      • Efficiency = Useful Energy Out / Total Energy In
        • To get a percentage then you have to multiply the answer of the efficiency by 100
      • Efficiency =  Useful Power Out / Total Power In
        • To get a percentage then you have to multiply the answer of the efficiency by 100
    • Convection, Conduction & Radiation
      • Radiation
        • An object that is hotter than its surrounding emits more radiation than it absorbs, (as it cools down).
      • Convection
        • Convection occurs when the more energetic particles MOVE from the HOTTER REGION towards the COOLER REGION - and take their heat  energy along with them.
        • Convection Currents  are all about CHANGES in DENSITY
      • Conduction
        • Conduction is the transfer of heat  between substances that are in direct contact
        • The better the conductor the more the heat would rapidly transfer.
    • Solar System
      • Redshift is evidence that the universe is expanding.
      • CMBR = Cosmic Microwave Background Radiation
    • Waves
      • Longitudinal Waves
        • In LONGITUDINAL waves the oscillations (vibrations)  are PARALLEL to the DIRECTION  OF ENERGY
      • Transverse Waves
        • Electromagnetic waves are transverse waves, since the electric and magnetic fields oscillate at a right angle to the direction of motion.
  • Energy
    • Energy  CANNOT be created or destroyed
    • Energy can be transformed . i.e. Television (Chemical) : Electrical, Thermal,  Light and Sound Energy
    • Dissipated (a word they like to use, to confuse): Energy is spread out and lost.
    • Energy is only useful when converted from one form to another.
