Motion ## 1. Velocity

### 1.2. What is it?

1.2.1. Velocity is speed in a given or specific direction.

1.2.2. Acceleration

## 2. International System of Units (SI)

### 2.2. What is it?

2.2.1. The international system of units is a system of measurements used to measure things such as motion. This system is used globally world wide so that all scientists can be synchronized and communicate clearly.

## 3. Motion

### 3.1. Reference Points

3.1.1. Stationary Objects serve as the best reference points as they make it easier to measure the motion.

3.1.2. A place or object used to compare to see if the object is in motion.

### 3.2. What is it?

3.2.1. Motion itself is when the distance between an object and another object is changing.

## 4. Speed

### 4.1. What is it?

4.1.1. The distance an object travels in respects to or per unit of time.

4.1.2. The formula to calculate Speed is Distance over time.

### 4.2. Instantaneous Speed

4.2.1. The rate or speed of which the object is moving at a specific instant within the total time.

### 4.3. Average Speed

4.3.1. Is the amount of average speed (rate) throughout a distance.

4.3.2. The Formula for average speed is total distance over total time.

## 5. Slope

### 5.1. What is it?

5.1.1. Slope itself is the steepness of a line on a graph.

5.1.2. Slope is calculated by rise over run.

5.1.3. The rate of change can be found by looking at the slope. So the slope can help determine the speed.
