What is a vector? Well, what most physics students in high-school learn about is that they are mathematical objects that have both “magnitude and direction”, i.e. they’re essentially arrows in space.

Note: they can have an arbitrary number of “components” to them, so there really is such a thing as a “56 dimensional vector” existing in 56 dimensional space! (though, when will that ever be useful?)

Vectors are used to represent a *lot* of things in the physical world, so the results and **Theorems** concerning them really are important, as they might give you some more insight into what’s going on in the real world.

Some things vectors are used to represent: Forces, velocity and acceleration, **Torque**, angular velocity, **Current**, and more.
