Introduction to Physical Quantities

Vectors: Scalars:
 * have a magnitude
 * have a direction
 * e.g. 6 metres [Right], driving 60km/hr [North]
 * without magnitude AND direction, the quantity will not be a vector
 * have a magnitude
 * do not have direction
 * e.g. Volume of brick is 10 grams (just has a magnitude/ size)
