... Scalars add, subtract, multiply the way we're used to. Vectors need to account for direction – may need trig. If parallel or antiparallel, then can treat more simply. If not – need to use trig. Magnitude of vector is its ‘size’ (ignore direction) The magnitude of a vector “3 m to the left” is 3 m Bo ...
