First, a brief definition of what a law is. A LAW is a statement that describes a natural phenomenom; a principle. A law begins as a theory. A theory is an idea that explains something, but has not been proven. Once a theory has ben proven, it becomes a LAW. Here is an explanation to all of the laws mentioned throughtout our page!

The Law of the Conservation of Energy states that the energy of a system cannot be created nor destroyed, but it can be converted from one kind to another.


The Law of the Conservation of Mass is a relation stating that in a chemical reaction, the mass of the products must equal the mass of the reactants.


Newton's Law of Universal Gravitation states that the force of attraction between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers of mass.


Newton's first law of motion or The Law of Inertia states that a body at rest will remaina at rest unless it's acted upon by an outside net force. The second part of this law is just the opposite: A body in motion will remain in motion unless it is acted upon by an outside net force.


Newton's Second Law of Motion explains that if you apply a net force to an object, the object goes from no motion to motionand that there will be a proportional acceleration.


Newton's Third Law of Motion states that for every action there is an equal and opposite reaction.


The Law of Magnetic Poles explains the general rule that like poles of a magnet repel each other and unlike poles attract each other.

Those are the laws, now lets look at some of the Theories that are mentioned throughtout our web page. Remember, Theories are different than laws in that they have not yet been proven.

The Kinetic Theory states that the molecules of matter are in constant motion and that collisions between molecules are perfectly elastic.


The Wave Theory is nothing more than the idea that light travels in waves rather than particles. Christian Huygens first came up with this theory. It is now recognized as Huygens' Principle. Another way of saying it is: Each point on a wave front may be reguarded as a new source of disturbance.


The Particle Theory is an idea of Isaac Newton that light traveled in particles called "corpulscles".
