2day i started a new topic inj physics and there were a few terms which i am unsure of. if velocity is the change of displacement over time, and acceleration is the change of velocity, and if speed is the change of distance over time, what is the change of speed over time? also i have come across a few formulas for this topic, these formulas are listed below(adsbygoogle = window.adsbygoogle || []).push({});

[tex]s = ut + \frac{1}{2} at^2[/tex]

[tex]v = u + at[/tex]

[tex]v^2 = u^2 - 2as[/tex]

[tex]v_{average} = \frac{s}{t}[/tex]

[tex]a_{average} = \frac{v - u}{t}[/tex]

are these all the formulas that are required for this topic or are there more? i understand that in some cases they may need to be rearanged.

many thanks,

Pavadrin
