The net force behind the pulley system can be calculated. This is an example using the word net force.
A net force is when two forces act in the same direction; for example, if you push a box to the right with a force of 10 N and someone else pushes it to the right with a force of 5 N, the net force on the box is 15 N to the right.
An example of net force in real life is when you push a shopping cart in one direction while someone else simultaneously pushes it in the opposite direction. The resulting net force will determine the cart's overall motion.
To find the net force, subtract the smaller force from the larger force. Net force = 70N - 45N = 25N. Therefore, the net force is 25 Newtons.
You must know the the direction so then you know if you either subtract or add. For example , if the the direction of the force is in opposite then you would have to subract each net force.

If you combine all the forces in your problem , using vector addition, the resulting answer is the "net force" As a simple example if you have a force of 10 N pointing right and a force of 3 N pointing left then because they are in opposite directions the net force will be 7 N pointing right.
Inertia will not be affected when "net" or "net force" is zero.
You will have to learn a new terminology here: net force. Net force is the sum of all forces acting on an object. For example, in a tag of war, when one team is pulling the tag with a force of 100 N and the other with 80 N, the net force would be 20 N at the direction of the first team (100 N - 80 N = 20 N).
To find the net force, subtract the smaller force from the larger force. Net force = 70N - 45N = 25N. Therefore, the net force is 25 Newtons.
