**This is where practically everyone's journey into physics starts, regardless of how far one takes
their physics education. Everyone understands what it means for something to be in motion in that it
is not standing still, it is moving in some manner. However, what is not so intuitive is how we describe
this act of being in motion through the language in which the universe speaks, mathematics. This mathematical
description of motion is generally referred to as kinematics. In this section we discuss the basic
concepts of motion, vectors & coordinates, and kinematics in 1 & 2 dimensions. Also, we provide thoroughly
worked examples, as well as calculators you can use to help you quickly calculate equations with your values.**

**Once one has a grasp on kinematics the next step is to understand the phenomena that drives the motion
that is discussed in kinematics. These phenomena are referred to as forces and are the causes
that drive the motion, the effects. Here we discuss Newton's Laws, give a brief overview of
various forces, dive more in depth into motion, and work through setting up 'free-body' diagrams which
can be extremely helpful when tackling physics problems.**

*Conservation* is the notion that a certain property does not change throughout an
interaction. This is a very import concept in physics because it provides information about a
property within the system that is repeatedly measurable over time, and remains consistent with each
measurement. Taking this deeper there is something called *Noether's Theorem* which states that
every differentiable symmetry of the action of a physical system has a corresponding conservation law.
We will not dive into Noether's Theorem or symmetries in this section but it is a good concept to keep
in mind while you make your way through this material. Here we discuss Work, Interactions, Kinetic &
Potential Energy, Impulse, and Momentum. There are worked examples, and equation calculators to help
you more efficiently work through your calculations.

**Here we apply kinematics, dynamics, and conservation laws into progressively more complex systems.
We discuss rotation of a rigid body, Newton's theory of gravity, fluids, and elasticity. It is not enough
however to simply work out problems with no explanation or reason as to why certain steps are taken or
why certain items are assumed so we shall attempt to thoroughly explain what is done, and why. Also, we
take an introductory look at what it means to be in an inertial reference frame compared to non-intertial
and the effects this has on the equations. **
