The variables shows the relationship between the different parts of the law.
For example, Newton's law of universal gravitation is expressed mathematically as shown below;

where G, m and r are all variables.
G is the universal gravitation constant
m is mass
r is the distance between them.
F is the gravitational force.
Most scientific laws are often expressed in this format.
