    - - Blue Stars: burn up hydrogen, other gases burn, turns to red supergiant, cools, outer layesrs collapse, supernova.
    - - Bigger objects have more gravity
      - weight = mass x gravitational field
        
        40kg x 9.8N/kg = 392N
  - - - Amplitude - distance form trough or crest to centre line
      - Trough - lowest point of wave
      - Crest - highest point of a wave
      - Wavelength - distance from crest to crest or trough to trough
  - - - P = F / A
      - 100N / 1m2 = 100N/m2 = 100Pa
    - - Amount of air particles
      - Air particles bounce of objects so the less particles the less pressure on the object.
