 # Net Force and Translational Equilibrium
+Net force is the vector sum of all individual forces in a system. 
 
-
+Translational equilibrium is when it equals to zero. The derived equation is $\Sigma \vec{F}=0$

 # Newton’s First Law
 Unless an external force acts on an object, an object in motion stays in motion and an object at rest stays at rest.

+# Newton’s Second Law
+Essentially the formula: $$\vec F=ma$$ and $$\vec a_{sys}=\frac{\Sigma \vec F}{m_{sys}}$$
+$\vec F$ represents force, m mass, and a acceleration.
