Forces are vectors, which means they need to be determined by not only their numeric value (amount of force in Newton's) but also their direction.

Some other examples of vector quantities include displacement, acceleration,  velocity, and momentum.  Each of these isn't complete until you know its size and direction.

There are other quantities that have size but no direction.  They include distance, speed, volume, temperature, cost, and loudness.  These are called "scalars".
