Let's break down the definitions of speed and velocity based on the information you provided.
1. **Includes an object's direction.** - This describes **velocity.** Velocity is a vector quantity that includes both the speed of the object and the direction in which it is moving.
2. **Example: The train is going 45 kilometers per hour.** - This example is of **speed.** It only provides the magnitude of the motion (the speed) without any direction.
3. **Example: The car is headed west going 60 miles per hour.** - This example is of **velocity.** It provides both the speed (60 miles per hour) and the direction (west).
Therefore, the breakdown is as follows:
- **Speed**
- Does not include direction.
- Example: "The train is going 45 kilometers per hour."
- **Velocity**
- Includes direction.
- Example: "The car is headed west going 60 miles per hour."
