Second Equation of Motion:

Second Equation of Motion:

Average Velocity = Total distance traveledTotal time takenAverage Velocity = st.....(1)

Average Velocity can be written as u+v2
Average Velocity = u+v2........(2)
From equations (1) and (2)
st = u+v2 .......(3)

The first equation of motion is v = u + at.

Substituting the value of v in equation (3) we get

st = (u+u+at)2
s = (2u+at)t2 = 2ut+at22 = 2ut2 + at22 Second equation of motion.
