Laws of Physics


Newton's Laws of Physics

In this section Newton's Laws are defined and described. Each law applies in an inertial frame of reference. They are:

Newton's The First Law: Every body that is at rest will remain at at rest unless acted upon by external forces

Newton's Second Law: The force (meaning the net force, aka total force) acting on a body equals the time rate of change of momentum, i.e. F= dp/dt.

Newton's Third Law: All forces between two objects have equal magnitude and opposite direction. If one object A exerts a force FA on a second object B, then B simultaneously exerts a force FB on A, and the two forces are equal and opposite: FA = −FB.

This section elaborates on Newton's three laws and gives several examples.

Maxwell's Laws of Electrodynamics

In this section Maxwell's Equations are given in both standard form and covariant form.

Postulates of Quantum Mechanics

This section provides a list of the postulates of quantum mechanics, the interpretation of the wavefunction and a few illustrative examples.

Postulates of Special Relativity

This section states the postulates of special relativity and the theorems derived from them such as the Lorentz transformation, time dilation, Lorentz contraction as well as both velocity, acceleration, force and energy transformations.

Postulates of General Relativity

This section states the postulates of general relativity. [TBD]
