You may be familiar with Newton's Second Law of Motion, SF = mā. In English, this equation says: The sum, or net, (S) of the forces (F) acting upon an object equals (=) the mass (m) of the object multiplied by the object's acceleration (ā). Even if you are familiar with this famous equation, did you notice the arrows above F and a before?...
