Question

in second law of motion 's' is distance or displacement

Answer 1

newtonian law ?

Answer 2

This law?
\[ s = ut + \frac{1}{2}at^2 \]
or
\[ s = s_0 + v_0t + \frac{1}{2}at^2 \]
Here, \( s \) is displacement.

Answer 3

s represents displacement but can some times be considered to be used as distance

Answer 4

relation that you want isn't law it's a equation of motion

Answer 5

Yes, technically what I've written isn't a Law of Motion, but just an equation of motion. In the three Newtonian Laws, there is no variable "s", that's why I went to one of the kinematic equations of motion instead.
