So in this question, they say i have three different forces that act on an object.
00:06
They are f1, which has components negative 3 and negative 7.
00:10
F2, which has components negative 2 and 5.
00:15
And f3, which has components 1 and negative 6.
00:19
And we want to find the net force on the object, which is defined to be the sum of the forces.
00:27
So how do we figure out the sum of the? the forces, i'm looking for f1 plus f2 plus f3 this time.
00:41
And so i'm adding the three vectors, negative 3, negative 7, plus negative 2, 5, plus 1 negative 6.
00:55
So to add vectors, all i do is add the respective components...
