Why can't two numbers with the same dimensions be added together in terms of physics?
There are some classes of numbers that can and others that cannot. Scalars can. Vectors usually cannot, if to add two vectors together you simply add their numerical values. Their directions - a characteristic of the vectors but which has no dimensions - need to be taken into account.
Methods for finding the resultant vector?
You can add vectors graphically, by drawing them head-to-tail. Algebraically, you can separate them into components (for example, in two dimensions, the horizontal and the vertical component), then add those.
At what condition can we add two vectors vectorically?
When the angle between the two vectors are not a multiple of 180 degrees.
How would you add two vectors that are not perpendicular or parallel?
To add two vectors that aren't parallel or perpindicular you resolve both of the planes displacement vectors into "x' and "y" components and then add the components together. (parallelogram technique graphically)
