A Scalar (ex: mass) has a magnitude but not a direction.
A Vector (ex: velocity) has both a magnitude and a direction.
Can you give any examples of quantities that have a direction but not a magnitude? Are these still called vectors or is there another term for them?

Sure... bearings have direction but not magnitude, for example, 20 degrees north by east. I wouldn't call them vectors because they're only directions, without magnitude.

nah by definition a vector must have some magnitude and a direction... Technically you can add a zero vector to somthing but that is the same as adding 0 to a scalar so it really is nothing.
