Without a doubt. Let's say you have an object that has been falling through air for a long time, for example, a skydiver. After falling for a long time, the skydiver falls at a constant speed. This is called terminal velocity, and this is when the air resistance pushing up around the skydiver is equal to the force of gravity pulling the skydiver down. The skydiver is not accelerating. Through the use of F= ma, with acceleration of zero, is zero the net force. The skydiver is moving as if there are forces acting on the parachutist.
