Net Positive or Negative Force

Two forces can add or subtract to the net force when the forces act on each other.  Forces in the same direction working togeather equal a net force.

 

Positive or Negative Force formulas

\(\large{ F_n = F_1  +  F_2 }\)
\(\large{ F_n = F_1 -  F_2 }\)

Where:

\(\large{ F_n }\) = net force

\(\large{ F_1 }\) = force 1

\(\large{ F_2 }\) = force 2
