Answer 1

First, consider a body moving in a straight line with uniform acceleration. Then, let the initial velocity be u, acceleration be a, time period be t, velocity be v,

It is known that the acceleration (a) of the body is defined as the rate of change of velocity.

So, the acceleration can be written as:

a = v − ut

From this, rearranging the terms, the first equation of motion is obtained, which is:

v = u + at
