Displacement

Uniform motion

Non - uniform motion

Object cover equal distance
in equal time

Object does not cover equal
distance in equal time

Speed = distance \ time

Average speed = total distance by time

Velocity - speed with direction

Velocity = displacement /time

Average velocity = initial velocity +final velocity/2

Acceleration = rate of
change of velocity

Acceleration = final velocity - initial velocity/time

Graphical representation of motion

Distance time graph

Velocity time graph

X-axis = time
Y-axis = distance

X-axis = time
Y-axis = velocity

Area under velocity Time graph
represent displacement

Equation of motion

First equation

v = u + at

Second equation

S = ut + 1/2 at^2

Third equation

2as = v^2 + u^2

Uniform circular motion
