When vectors are added or subtracted what is the net force called?

The sum of vectors is not always a force. It might be a displacement, a velocity,
acceleration, momentum, divergence, curl, gradient, etc.
In any case, the algebraic combination of several individual vectors is the "resultant".

What do you get when you subtract the force of air resitance from the force of gravity?
First of all, gravity is not a force, it is an acceleration. What you mean is the force of weight, which is the acceleration of gravity multiplied by mass (all forces are vectors, and gravity is not a vector.) When air resistance is subtracted from weight, you have the net force on a falling object (assuming those are the only forces acting on it.)
When can forces be added together to find the net force upon an object?
Yes, when all the forces acting on a body have been resolved, the final force is known as the 'net force' acting on that body.
When are force said to be added and when are they subtracted?
if two forces act in same direction they r added and if they act in opposite direction they r subtracted
What is the sum of to vectors?
A variety of mathematical operations can be performed with and upon vectors. One such operation is the addition of vectors. Two vectors can be added together to determine the result (or resultant). This process of adding two or more vectors has already been discussed in an earlier unit. Recall in our discussion of Newton's laws of motion, that the net force experienced by an object was determined by computing the vector sum of all the individual forces acting upon that object. That is the net force was the result (or resultant) of adding up all the force vectors. During that unit, the rules for summing vectors (such as force vectors) were kept relatively simple. Observe the following summations of two force vectors:
What is muscle force and its vector representation?
Muscle force is the force produced by the contraction of a muscle. Force vectors, torque vectors, and difference vectors can all be used to help describe this force.
Can velocity vectors be combined with force vectors?
No
How can you find the net force if two forces act in the same direction?
forces in the same direction can be added to give us the resultant force and opposite force will subtracted to get resultant force
Do velocity vectors combine with force vectors?
simply: No, Velocity vectors are different to force vectors. One measures velocity and one measures force so you can not simply add/subtract/multiply/divide them together and get something meaningful.
Why must you know the directions when finding net force?
Forces are vectors and, like all vectors, they have magnitude and direction. Forces can be added together using vector addition and to do so, it is necessary to know their directions.
When two forces act on the same object in opposite directions is the smaller force subtracted from the larger force?
yes, result is called the net force
What is the resultant force if the first force has an upward vector and the second force has a downward vector?
If the two vectors are directly opposite each other, then subtract the smaller one from the larger one and that will be your resultant force. For example, if the force downwards is 5 N and the force upwards is 2 N, the resultant force is 3 N downwards. If the one or both of the two vectors are angled, you need to replace the angled vectors with two right-angled vectors and then add those to create the resultant vectors.
When is a newton added or subtracted?
A newton is a unit of force. It only makes sense to add (or subtract) this with other forces. Usually vector addition is used.
