Can anyone tell 4th equation of motion.

We know the first equation of motion,

v = u + at

Second equation of motion,

s = ut + 1/2 at

^{2}

The third equation of motion,

v

^{2}= u

^{2}+ 2as

The fourth equation of motion,

The distance travelled by a body in t

^{th}second (S

_{t}) = The difference between the distance travelled in t seconds and distance travelled in (t-1) seconds.

S

_{t}=( ut +1/2 at

^{2}) - {u(t-1) + 1/2 at

^{2}}

= u + a [n - 1/2]

where:

u = initial velocity, v = final velocity, a = uniform acceleration, s= distance travelled, t = time period in seconds

Regards.
