The Law of Conservation of Energy	Energy cannot be created or destroyed, only changed in form.
Inertia	A property of matter that causes any object to prefer its current state of motion, and resist changing it.
Newton's First Law of Motion	In the absence of a force, an object will remain in its present state of motion-either at rest, or moving at a constant speed in the same direction.
Newton's Second Law of Motion	The acceleration of an object is proportional to the force acting on it. a = F/m F = a x m
Newton's Third Law of Motion	When one object pushes on another with a certain force, the second object pushes back on the first one with equal force.
Wave	A disturbance in space and time that carries energy from one place to another.

Refraction	When passing from one medium to another, waves change direction (Refract) if the velocity of the wave is different in the two media.
Diffraction	The bending and the spreading out of waves as they pass corners or obstructions.
Ohm's Law	V = I x R The voltage difference is equal to the product of the current and resistance.
Ampere's Law	A current-carrying wire produces a magnetic field around it, and the strength of the magnetic field is directly proportional to the current of the wire.
Faraday's Law of Magnetic Induction	A changing magnetic field near a coil of wire induces a current in the coil.
