Gravitation and the law of motion could not explain every- thing.

The laws that we have today explain the world as we understand it.

Coulomb's law explains how big the force will be.

The second law explains how a force acts on an object.

Neither law actually explains anything; they simply describe what happens.

Kleiber's law explains the relationship between the size of the animal and the feeding strategy it uses.

Newton's first law of motion explains that a moving object continues to move because it has momentum.

The law of supply and demand does not explain this.

Mendel's laws explained the results he got with his pea plants.

Each of them has different definitions and characteristics that the law explains.
