  1. displacement formuli
    ∆x=vi ∆t+ Image Upload 2 a (∆t)2
  2. displacement vs distance
    • displacement= net change in location
    • distnce= travel path lentght
  3. final velocity
    • vf2=vi2 +2ad
    • vf=vi+at
  4. Newtons first law
    An object at rest remains at rest, and an object in motion continues in motion with constant velocity (that is, constant speed in a straight line) unless the object experiences a net external force.
  5. newtons second law
    F=ma
  6. Newtons Third Law
    If two objects interact, the magnitude of the force exerted on object 1 by object 2 is equal to magnitude of the force exerted on object 2 by object 1, and these two forces are oppisate in direction.

  22. Keplers first law
    Each planet travels in an elliptical orbit around the sun, and the sun is at one of the focal points
  23. Keplers second law
    An imaginary line drawn from the sun to any planet sweeps out equal areas in equal time intervals
  24. keplers third law
    the square of a planets orbital period (T2) is proportional to the cube of the average distance (r3) between the planet and the sun, or Image Upload 20

  36. Isovolumetric
    • No work done
    • ∆V=0
    • so P∆V=0 and W=0
    • Therefor ∆U=Q
  37. First Law of Thermodynamics
    ∆U=Q-W
  38. Isothermal
    • No change in temperature or internal energy
    • ∆T=0 so, ∆U=0; therefore, ∆U=Q-W=0; or
    • Q=W
  39. Abiabatic
    • no energy transferd as heat.
    • Q=0, so ∆U= -W
  40. Isolated system
    Ui=Uf
