# Net Positive or Negative Force

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

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.

## Net Positive or Negative Force formulas

$$\large{ F_n = F_1 + F_2 }$$

$$\large{ F_n = F_1 - F_2 }$$

Symbol English Metric
$$\large{ F_n }$$ = net force $$\large{ lbf }$$ $$\large{N}$$
$$\large{ F_1 }$$ = force 1 $$\large{ lbf }$$ $$\large{N}$$
$$\large{ F_2 }$$ = force 2 $$\large{ lbf }$$ $$\large{N}$$
