Question

Formula of velocity?
Formula of speed?​

Answer 1

These are explained below:

First Equation of Motion: (Velocity-Time Relation) v = u +at. Where, v = Final velocity of body. u = Initial velocity of body. a = Acceleration. And t = Time. Derivation: Using formula for acceleration: ...

Second Equation of Motion: (Position-Time Relation)

Third Equation of Motion:

Answer 2

$average \: velocity= \frac{displacement}{change in time}$

$formula \: of \: speed \\ s = \frac{d}{t}$
