Linear motion

Cards (15)

  • s is displacement ( m )
  • u is initial velocity ( m/s )
  • v is final velocity ( m/s )
  • a is acceleration ( m / s ^2 )
  • t is time ( s )
  • v = u + at
  • v ^2 = u ^2 + 2 a s
    v2=v^2 =u2+ u^2 +2as 2as
  • v = u + a t
  • distance = initial velocity x time + 0.5 acceleration x time squared
    s=s =ut+ ut +12at2 \frac {1}{2}at^2
  • s=s=(u+v2)t\left(\frac{u+v}{2}\right)t
    distance = initial + final velocity / 2 x time
  • v = s / t
    velocity = displacement / time
  • instantaneous speed = absolute value of the gradient of distance vs time graph
  • average speed = total distance travelled / total time taken
  • km / h to m / s
    shortcut (km / h) / 3.6
  • m/s to km/h
    shortcut (km/h) x 3.6
