WebIn this lesson, we defined scalar and vector quantities. And we saw that the vital difference between them is that a scalar quantity has a magnitude only, while a vector quantity has both magnitude and direction. We saw further that a scalar and a scalar or a vector and a vector can be added or subtracted if their units agree. WebScalar. Mass does not have any direction, and it will be the same no matter where you are in the universe! So we can categorise mass as a scalar quantity.. Vector. Weight, on the other hand, is the force acting on an object, and since force has a direction, weight is a vector quantity. Another way to look at this is if you place one object on Earth and … WebThe magnitude of a vector, however, we know is a scalar (from the definition of dot products and other things). Therefore, the magnitude of a “time vector” being its only component, would mean that time has to be a scalar.. The bottom line here is that it makes more sense to think of time as a scalar rather than a vector (in Newtonian physics, that is). hull community centre
