Constant Speed

• At constant speed, $a\ =$$\ 0$
• $dist\ =$$\ speed\ \times time$
• To convert from $kmph$ to $ms^{-1}$ :

  $\times1000$ then $\div60$ then $\div60$
• To convert from $ms^{-1}$ to $kmph$ :

  $\div1000$ then $\times60$ then $\times60$
• Vector motion: $\underline{r}\$ = $\underline{r}_0\ +$$\ \underline{v}t$
