I'm studying for my science final (i'm in 9th grade) and I don't understand net force. Can you explain what it is in a simple way?
Also, he gave us this [ractive question to know how I'll need to apply that knowledge. The question is:
Force1 is 15N, the box has a mass of 20 kg and is accelerating 2 m/s^2. What is its net force?
Can you explain how to do this problem with clear steps.?
Thank you so much!

Net force is pretty much the amount of force that is being exerted on an object that is not completely balanced out by another force. For example, the box that you describe in your problem, we can assume that is is sitting on the ground. The force of gravity is pulling the box down into the ground, while the force normal is counteracting that force to push the box back up off the ground with the exact same amount of force. When two forces cancel each other out like that, the net force is 0 in that direction (in this case the up-and-down direction/y axis).
In the problem you describe, the net force would just be 15N, unless it states that there is gravity or force pushing in another direction as well. That would be the only force not cancelled out by another.
