2.4.A.1Concept
The net force exerted on a system is the vector sum of all the individual forces exerted on the system.
ExampleTwo people pushing a cart the same way1 / 3
Two people push the same cart in the same direction: one with 300 N, the other with 150 N. Find the net force on the cart.
Try it on paper first, then reveal each step to check your work.
Step 1 — Check the directions
Both forces point in the same direction, so this is the simplest possible vector sum — plain addition.
