I do not understand Net Force at all- I would really appreciate it! I'll also include a brainliest since it is quite a bit! Thank you!

Answer:
See below
Explanation:
Net Force is the force which is the sum of all the forces acting on object i.e. pushing of pulling.
Net Force:
1) 4N (net force is 4N to the left)
2) 2 - 7 = -5N (net force is 5N to the left)
3) 4 - 4 = 0 (net force Zero)
4) 6 + 3 = 9N (net force is 9N to the right)
5) 4 - 8 = -4N (net force is 4N to the left)
6) 4 - 5 = -1N (net force is 1N to the left)
7) -3 - 3 = -6N (net force is 6N to the left)
8) 2 + 4 - 5 = 1N (net force is 1N to the right)
9) 3 - 6 = -3N (net force is 3N to the left)
10. 4 + 4 - 7 - 1N (net force is 1N to the right)
