## Kinematics

Kinematics is all about motion. Motion is a change in position relative to a **frame of reference**

### Vocabulary

scalar vs vector distance vs displacement speed vs velocity frame of reference acceleration

### Vectors

Vectors can be manipulated in two ways, by trigonometry or on a Cartesian coordinate system

### The four kinemetic equations

## Forces

### The four fundamental forces

Gravity, electromagnetic, strong nuclear, weak nuclear

### Newtons Laws

- A body in motion stays in motion and a body at rest stays at rest, unless acted on by an outside force
- $\overrightarrow{F}=m\overrightarrow{a}$
- For every action, there is an equal and opposite reaction. Or to be more precise, when one body exerts a force of $\overrightarrow{F}$ on a second body, the second body exerts a force of $-\overrightarrow{F}$ on the first body. - Newtons laws, friction, gravitation
## Energy

- work, force, conservation of energy - heat

## Waves and Sound

## Electricity and Magnetism

## Resources

The Physics Classroom - basically covers everything Kinematics Fundamentals - this too
