Motion in a Straight Line

distance = actual path length

displacement = final position - initial position

speed = distance / time

v_av = Total distance covered / Total time taken

v_av = (2 v1 v2) / (v1 + v2)

slope of position-time graph = velocity

slope of velocity-time graph = acceleration

area under velocity-time graph = displacement

area under acceleration-time graph = change in velocity

v = u + at

s = ut + (1/2)at^2

v^2 = u^2 + 2as

s(th) = u + (1/2)a(2t - 1)

s ∝ t^2
