Show Answer Key & Explanations
Step-by-step solution for: Speed, Velocity, and Acceleration
To solve the problem, we need to analyze each statement and determine whether it describes speed, velocity, or acceleration. Here's a breakdown of each term:
- Speed: The rate at which an object covers distance, without considering direction (a scalar quantity).
- Velocity: The rate at which an object changes its position, including both speed and direction (a vector quantity).
- Acceleration: The rate at which velocity changes over time, including changes in speed and/or direction (a vector quantity).
Now, let's go through each statement and label it accordingly:
---
- This includes both the distance (23 km) and the direction (south). Therefore, it is velocity.
- Answer: V
---
- This describes a change in speed (slowing down), which is acceleration.
- Answer: A
---
- This describes the rate of travel (distance per unit time) without mentioning direction. Therefore, it is speed.
- Answer: S
---
- This describes a change in speed (sped up), which is acceleration.
- Answer: A
---
- This describes a change in speed (increased speed), which is acceleration.
- Answer: A
---
- This describes the rate of travel (speed) without mentioning direction. Therefore, it is speed.
- Answer: S
---
- This describes the rate of travel (distance per unit time) without mentioning direction. Therefore, it is speed.
- Answer: S
---
- This describes the rate of travel (distance per unit time) without mentioning direction. Therefore, it is speed.
- Answer: S
---
- This includes both the rate of travel (500 mph) and the direction (north). Therefore, it is velocity.
- Answer: V
---
- This includes both the rate of travel (8 kph) and the direction (westward). Therefore, it is velocity.
- Answer: V
---
- This describes a change in direction, which is acceleration.
- Answer: A
---
- This describes the rate of travel (40 mph) without mentioning direction. Therefore, it is speed.
- Answer: S
---
- This includes both the rate of travel (30 mph) and the direction (westward). Therefore, it is velocity.
- Answer: V
---
- This describes the rate of travel (distance per unit time) without mentioning direction. Therefore, it is speed.
- Answer: S
---
- This describes a change in speed (sped up), which is acceleration.
- Answer: A
---
```
V, A, S, A, A, S, S, S, V, V, A, S, V, S, A
```
Thus, the final answer is:
\boxed{V, A, S, A, A, S, S, S, V, V, A, S, V, S, A}
- Speed: The rate at which an object covers distance, without considering direction (a scalar quantity).
- Velocity: The rate at which an object changes its position, including both speed and direction (a vector quantity).
- Acceleration: The rate at which velocity changes over time, including changes in speed and/or direction (a vector quantity).
Now, let's go through each statement and label it accordingly:

1. The geese fly 23 km to the south when they migrate for the winter.
- This includes both the distance (23 km) and the direction (south). Therefore, it is velocity.
- Answer: V
---
2. The motorcycle slowed down as it approached the yield sign.
- This describes a change in speed (slowing down), which is acceleration.
- Answer: A
---
3. A drift car can travel 2 miles in 3 hours.
- This describes the rate of travel (distance per unit time) without mentioning direction. Therefore, it is speed.
- Answer: S
---
4. The race car sped up this turn as it went around the track.
- This describes a change in speed (sped up), which is acceleration.
- Answer: A
---
5. The train increased its speed as it left the terminal.
- This describes a change in speed (increased speed), which is acceleration.
- Answer: A
---
6. The car is traveling at 20 mph.
- This describes the rate of travel (speed) without mentioning direction. Therefore, it is speed.
- Answer: S
---
7. The jogger ran 3 miles in 28 minutes.
- This describes the rate of travel (distance per unit time) without mentioning direction. Therefore, it is speed.
- Answer: S
---
