# A 12-N falling object encounters 8 N of air resistance. What is the net force on the object?

$4 \setminus \text{N}$ downwards
The object is being pulled $12 \setminus \text{N}$ downwards as a result of the gravitational acceleration, while the force of air resistance, $8 \setminus \text{N}$, is acting upwards, and so the net force (in terms of downward motion) is:
$12 \setminus \text{N"-8 \ "N}$
$= 4 \setminus \text{N}$
