Question

A ball is dropped from the top of a building the gravitational force is 10 N down and the force air resistance is 1 N up what is the net force?

Answer 1

The net force on the object is 9N down.

Step-by-step explanation:

The given parameters;

gravitational force, Fg = 10 N

force of air resistance, Fr = 1 N

The net force on an object is defined as the change in the total force on the object.

Assuming the downward motion = positive direction

the downward motion = air resistance = negative direction

10n -1n=9n

Thus, the net force on the object is 9N down.
