Let's identify the correct descriptors for each variable based on the given descriptions.

### Descriptions:

1. **Directly proportional to the mass if acceleration is constant; Measured in newtons (N):**  
   - **Force**

2. **Rate of change of velocity; Measured in meters per second squared (m/s²):**  
   - **Acceleration**

3. **Distance and direction covered over a specified amount of time; Measured in meters per second (m/s):**  
   - **Velocity**

4. **Distance covered over a specified amount of time; Measured in meters per second (m/s):**  
   - **Speed**

### Matching Descriptions to Variables:

1. **Force:**
   - Directly proportional to the mass if acceleration is constant
   - Measured in newtons (N)

2. **Acceleration:**
   - Rate of change of velocity
   - Measured in meters per second squared (m/s²)

3. **Velocity:**
   - Distance and direction covered over a specified amount of time
   - Measured in meters per second (m/s)

4. **Speed:**
   - Distance covered over a specified amount of time
   - Measured in meters per second (m/s)

Would you like further details or have any questions?

Here are 5 related questions you might find useful:

1. How does acceleration differ from velocity?
2. Why is force directly proportional to mass when acceleration is constant?
3. Can you have speed without velocity?
4. What factors can change the acceleration of an object?
5. How does the direction of velocity affect the overall motion of an object?

**Tip:** When analyzing motion, always consider both the magnitude and direction to differentiate between velocity and speed effectively.
