  Magnetic Field
• Solid to Gas

  Sublimation
• Gas to liquid

  Condensation
• Liquid to solid

  Freezing
• Solid to liquid

  Melting
• Liquid to gas

  Vaporization
• Gas to solid

  Deposition
• F=ma


  Force equals mass times acceleration
• W = Fd


  Work equals force times displacement
• Concave (converging) mirror 


  creates a real image of an object positioned outside the mirrors focal length
• Convex (diverging) mirror


  Creates a virtual image
• Q=mc times change in T

  Q = heat M = mass c= specific heat and T= change in temperature
• F = c / lambda


  F = frequency c = speed of light and lambda = wavelength
• E = hf


  E = energy h = planck’s constant and f = frequency
• Photons with shorter wavelengths have higher energy and higher frequency
• Longer wavelengths refract less than shorter wavelengths
• P = W / T


  Power equals work over time
• F = uN


  F =friction u= coefficient of friction N=normal force
• F=uN = umg
• N = W = mg
• a = F/M 


  a = acceleration, F = force, M = mass
• shorter wavelengths = higher energy and higher frequency
• longer wavelengths = lower energy and lower frequency
• Monoamine neurotransmitters


  Serotonin Norepinephrine and Dopamine
• Visible spectrum

  Between 400 and 750 nm
• E=hf

  Energy = Planck constant times frequency
• Light travels fastest in vacuum and is slower in transparent material
• Larger wavelength of material


  slower light travel through it
