5.4 Resultant force
Resultant force
If forces act on an object in the same direction, force 1 (F1) and force 2 (F2) can be added directly,
For a hand-written vector, we use a half arrow on the top of the vector quantity, F. In this text book, we use a boldface letter to represent a vector quantity, F.
F1+F2 =1N, (to the right) and the resultant force has a direcrtion with F1.
The net force F1+F2 = 2n, (to the left) and the resultant with F2.
What happens if forces are not in the parallel direction?
