Linear & Projectile motion

Notations and units:

u = initial velocity, v = final velocity, t = time, a = acceleration, r = retardation, s = distance, g = acceleration due to gravity

Units of the notations are in SI units.

Linear motion:

  1. v = u + at
  2. v² = u² + 2as
  3. s = ut+ ½ at²
  4. s = ut – ½ rt²
  5. Distance traveled in the nth second = u + ½ a(2n-1)

Projectile motion:

  1. Time of flight t = u sinθ / g
  2. Range = u² sin2θ / g
  3. Maximum height = u² sin²θ / 2g
