1.1 Measurements in Physics
Note: units written out in full always use the lower case: meter, newton, pascal, ampere, second When the symbol for the unit is written, it may be upper case if named for a person: m, N, P, A, s
In certain situations, we will need to work out the angle between two adjacent vectors. In order to do this graphically we draw a scale diagram with the tail of one vector at the head of the other, we then draw a line connecting the other head and tail. To get the magnitude of the new vector, we simply measure it.
