Physics often use mathematics as its language. here you will be presented with a collection of mathematical techniques you will fins useful throughout your time. You might think of this as a collection of tools that can be used when needed later.
  Central to the tools is the graphs and equations to represent the results of many observations and experiments. Probably the most famous physics equation is E=mc??.
This simple equation describes one of the most powerful concepts of physics - the equivalence of mass and energy for a particle at rest.
  How do you an equation to describe experimental results? Frequently a graph of the data gives you a clue. You will see how data describing the distance a car travels while braking to a stop can be expressed by an equation. thus, you will learn that one of the most powerful ways of analyzing data is to display them as a graph.
