Answer:
Imagine a tug-of-war between you and one
friend. If you are stronger, you apply more
force to the rope. You pull your friend across
the line, and you are the winner! If your friend
is stronger, he might pull you across the line.
Sometimes the forces are equal. Neither you
nor your friend moves across the line. The two
forces are balanced.

We say that the net force on an object is the combination of all the forces acting on it. To find the net force of
forces that are acting in the same direction, add them together. For example, if you pull on a box with a force of 25
newtons (N) while your friend pushes the box (in the same direction you are pulling) with a force of 30 N, the net
force applied to the box in that direction is 55 newtons.

To find the net force of forces that are acting in opposite directions, subtract the smaller force from the larger
one. If you are pulling on a tug-of-war rope with a force of 40 N, and your friend is pulling with a force of 35 N in
the opposite direction, the net force on the rope is 5 newtons in your direction. You win!
