## anonymous 4 years ago in second law of motion 's' is distance or displacement

1. anonymous

newtonian law ?

2. JamesJ

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

3. anonymous

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

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

5. JamesJ

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.
