## 2. International System of Units

### 2.1. system of measurement

2.1.1. meters

2.1.2. kilometers

2.1.3. Millimeters

2.1.4. decimeters

2.1.5. centimeters

### 2.2. used for

2.2.1. origin

4.3.2. graphed

## 5. Acceleration

### 5.1. direction

5.1.1. increasing speed

5.1.2. slow down

5.1.3. change direction

### 5.2. calculation

5.2.1. finial speed - Initial speed / time

### 5.3. Velocity

5.3.1. speed in a given direction

5.3.2. rate
