Newton's First Law

Newton's First Law States: an object at rest stays at rest, an object in motion stays in motion with a constant velocity, if there is no net external force between the object and the environment. In equation form we can write:

 
$\displaystyle\Sigma$$\displaystyle\vec{F}$ = 0 $\displaystyle\Rightarrow$ $\displaystyle\vec{a}$ = 0.
