Motion
Motion alone straight line
Distance
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

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
no
SI unit = m/s^2
SI unit = m/s
SI unit = m/s
