(adsbygoogle = window.adsbygoogle || []).push({}); From kinematics we have [tex]a=\frac{\mathrm{d}^2s}{\mathrm{d}t^2}[/tex] which means,as I understood it:Code (Text):Question 1.to get the acceleration,we first derive distance with respect to time,then again derive the result of that operation with respect to time.

If so,wouldn`t be more appropriate to write [tex]a=\frac{\mathrm{d}^2s}{\mathrm{d}t}[/tex] - I mean,what [tex]2[/tex] represents in [tex]\mathrm{d}t^2[/tex]?
