Distance: (Δx, Scalar) How far something has traveled (total).

Displacement: (Δx, vector) Position relative to starting point, including magnitude and direction.

Constant/Average Speed or Velocity:

  • Use the equation v = Δx/Δt.
  • If finding speed (scalar), Δx = distance.
  • If finding velocity ,Δx = displacement.


Constant acceleration equations:

  • Δx = v0t + ½ at2
  • v2 = v02 + 2aΔx
  • v = v0 + at
  • a=Δv/Δt

Free Fall: a = -9.8 m/s2 (or -10m/s2), speed at highest point = 0, All objects fall at the same rate (a hammer and a feather will fall at the same rate) if there is no wind resistance.
