1. Waves

   • Longitudinal
     • Back and forth
     • Compression when the wave lengths are close together
     • Rarefraction were the wavelengths are spread out
   • Transverse
     • Up and down
     • Perpendicular angles
   • The bigger the amplitude in the waves the more energy is transmited
     • The wave length is the distance between to waves peaks/troughs
       • The peak is the top of the wave
       • The trough is the bottom of the wave
     • The longer the waves the higher the amplitude
       • The higher the wavelength the distance between the peaks are further apart
     • The shorter the waves the lower the amplitude
       • The lower the wavelength the distance between the peaks are closer together

2. Energy

   • 9 types of energy
     • Strain/elastic
       • Stored energy in stretched or squashed objects
     • Electrical
       • Energy in moving or static electric charges
     • Light
       • Energy that comes from the sun
     • Sound
       • Energy released by vibrating objects
     • Heat/thermal
       • Produces warmth of one type of form or another
     • Kinetic
       • The energy in moving objects
     • Chemical
       • Stored energy in fuel, foods and batteries
     • Gravitational potential
       • Stored energy in a raised object
     • Nuclear
       • Stored in the nuclei of atoms
