Question

Why are vectors important in physics?

Answer 1

Knowledge of vectors is important because many quantities used in physics are vectors. If you try to add together vector quantities without taking into account their direction you'll get results that are incorrect. Some of the key vector quantities in physics: force, displacement, velocity, and acceleration.

Answer 2

Answer:

In physics, vectors are useful because they can visually represent position, displacement, velocity and acceleration. When drawing vectors, you often do not have enough space to draw them to the scale they are representing, so it is important to denote somewhere what scale they are being drawn at.
