| ppefmh | Ed | Garstin | 1/1 | We carry out calculations involving velocity by using the same equation that we saw in the previous chapter. However, unlike with speed we have to state the objects direction. |  |

Speed is a scalar quantity because it only has magnitude (size) and not direction. However, velocity is a vector quantity because it has both magnitude and direction.
