  1. Three units to remember?
    MKS= meters/ kg/ sec

    CGS= cm/g/ sec

    ENG= feet/ slugs/ sec
  2. X =
    [L]
  3. V=
    [L/T]
  4. T=
    [T]
  5. Convert V to X:
    [L] = [L/T] [T]

    x=vt
  6. What does V0 mean?
    has velocity of the holder initially

    If the holder is moving, the initial velocity is that of the holder
  7. Explain gravity.
    a force downward. And since this is opposite of our coordinate system, it is usually negative
  8. Equation used for determining how fast something is?
    V= V0+at
  9. Interested in speed? Use:
    V^2=Vi2+2a(x-x0)
  10. To find position, what equation is used?
    x= x(initial)+ v(initial)t+ (1/2)at^2
  11. To find velocity under a constant acceleration?
    V= at+ v(initial)
  12. For velocity in terms of position?
    V^2=Vi2+2a(x-x0)
  13. Position as a function of Time and Velocity
    x= x0+(1/2)(v0+v)t
