Question

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

Answer 1

`4 \ "N"` downwards

Explanation:

The object is being pulled `12 \ "N"` downwards as a result of the gravitational acceleration, while the force of air resistance, `8 \ "N"`, is acting upwards, and so the net force (in terms of downward motion) is:

`12 \ "N"-8 \ "N"`

`=4 \ "N"`
