No, they sum up to twice one of the forces.
No, they are not. The forces are balanced only when forces of equal magnitude are acting in the opposite direction.
The forces are balanced, and the net force is zero
If the forces are equal then the net force is 0. If one force is greater than the other than whatever is having the two forces exerted on it will move in the direction of the greater force's direction. The total force will equal the greater force - lesser force. You can draw it in vectors to help visualize. e.g. F1 <------------------*-------> F2 let's say F1 = 5 newtons and F2 = 2 newtons. The combined force would equal 3 newtons going <- direction.
As long as it is not accelerating (going faster and faster, or slower and slower), the forces on the parachute are balanced. Initially, the parachute will accelerate - in this case the forces are unbalanced. It will continue accelerating, until the force of gravitation is balanced by the force of resistance.
2 Forces are unbalanced when an object that is not moving starts moving or changes speed or direction. Balanced forces are the opposite they are where an object that is not moving stays still or an object that is moving stays at a constant pace.
In the most general situation, net force on an object causes the object to accelerate in the direction of the net force. Under specialized conditions, net force might enable the sportsman to lift the exhausted fish gently out of the water, or it might reflect the inept serve back in the direction from which it arrived.
forces can be added only when they both are going in the same direction as 2n + 2n = 4n of force in the same direction if they are 2 facing forces they would have had to be subtracted, which ever force is greater that will be the momentum of the force
Yes but they will not make the object start, they will only work once the object is going and will keep the object going the same speed from when the unbalenced forces stop.
you would have to travel northwest.
You would be going south.
You would be going Southeast.
The object remains in constant, uniform motion. That means its speed and direction of motion don't change. Note that its speed may or may not be zero.
