Question

Write down critical comparison between 1st and 2nd equation of motion?

Answer 1

Explanation:

The first equation uses four variables :- v , u , a , t

The second equation uses four variables :- s , u , a , t

Answer 2

Explanation:

1st equation of motion

$v = u + at.$

2nd equation of motion

$s \: = ut + \frac{1}{2} at ^{2}$

In both the equations - initial velocity (u), time(t), acceleration (a) are used.
