Linear Motion

Outline

Termonology
- Scalar = magnitude or amount
- Vector = magnitude with direction
- Position [x]
- Displacement [(delta)x = x-xo]
- Distance [d]
- Speed [s = |V|]
- Velocity [V]
- Acceleration [a]
Constant Motion
- Constant Speed [s = |V| = d/t]
- Constant Velocity [average v = ((delta)x)/(delta)t]
Constant Acceleration
- Acceleration [a = (delta)V/(delta)t]
- Constant Acceleration Equations
  - V = Vo + at
  - V^2 = Vo^2 + 2a(delta)x
  - (delta)x = Vot + 1/2 at^2
  - (delta)x = 1/2 (V + Vo)t
