It's true that the vector sum of [itex]\vec{OB} + \vec{BA} = \vec{OA}[/itex]. But you don't add vectors by simply adding their magnitudes. To learn how to add vectors (there are several ways) explore the link I gave you earlier and this one: Vector Addition.synkk said:
Vectors are mathematical objects that have both magnitude (or size) and direction. They are commonly represented as arrows, with the length of the arrow representing the magnitude and the direction of the arrow indicating the direction.
Scalars only have magnitude, while vectors have both magnitude and direction. For example, temperature is a scalar quantity because it only has a numerical value, but velocity is a vector quantity because it has both a magnitude (speed) and a direction.
Vectors are important in science because they are used to represent physical quantities such as force, acceleration, and displacement. They are also essential in many mathematical and scientific fields, such as physics, engineering, and computer graphics.
To add or subtract vectors, you must first make sure they are in the same direction. Then, you can add or subtract the magnitudes of the vectors to get the magnitude of the resulting vector. The direction of the resulting vector will be the same as the direction of the original vectors.
Yes, vectors can be negative. The direction of a vector can be positive or negative depending on its orientation. For example, a vector pointing to the right may have a positive direction, while a vector pointing to the left may have a negative direction.
