Summing the forces is nothing new, it is vector addition. This video compares summing the forces to graphical vector addition. This video builds off the previous video "[url="http://www.flippingphysics.com/three-force-example.html"]A Three Force Example of Newton's 2nd Law with Components[/url]â€ which you should watch first.
0:31 The first example
0:59 The second example
1:20 The third example
1:40 The fourth example
1:58 Using a data table
2:26 Reviewing all the examples visually
