Step-by-step solution for: Speed, Velocity, and Acceleration | Ciencias naturales, Física ...
Sure! Let’s solve the problem step by step.
The worksheet asks you to label each scenario with the correct word: speed, velocity, or acceleration.
---
- Speed: How fast something is moving — a scalar quantity (only magnitude, no direction).
Example: “60 km/h”
- Velocity: Speed in a specific direction — a vector quantity (magnitude + direction).
Example: “60 km/h north”
- Acceleration: The rate at which velocity changes — includes speeding up, slowing down, or changing direction.
Example: “5 m/s²” or “slowing down from 20 m/s to 10 m/s”

Now let’s go through each sentence:
---
1. The geese fly 23 km to the south when they migrate for the winter.
→ This gives direction (“south”) and distance over time (implied migration speed), so it’s describing velocity.
✔ Answer: Velocity
---
2. The motorcycle slowed down as it approached the yield sign.
→ Slowing down = change in speed → that’s acceleration (negative acceleration, or deceleration).
✔ Answer: Acceleration
---
3. A snail can crawl 2 meters in 2 hours.
→ Only distance and time — no direction mentioned → this is speed.
✔ Answer: Speed
---
4. The race car sped from the turn as it went around the track.
→ “Sped” implies increasing speed → change in velocity → acceleration.
✔ Answer: Acceleration
---
5. The train increased its speed as it left the terminal.
→ Again, increasing speed → acceleration.
✔ Answer: Acceleration
---
6. The car is traveling northwest at 20 mph.
→ Gives both speed (20 mph) AND direction (northwest) → velocity.
✔ Answer: Velocity
---
7. The jogger ran 3 miles in 28 minutes.
→ Only distance and time → speed.
✔ Answer: Speed
---
8. The soccer player ran 50 yards in 5.5 seconds.
→ Distance and time only → speed.
✔ Answer: Speed
---
9. The jumbo jet is traveling at 500 mph to the north.
→ Speed + direction → velocity.
✔ Answer: Velocity
---
10. The SUV traveled west towards Denver, China at 65 mph.
→ Wait — “Denver, China”? That’s likely a typo. Denver is in the USA, not China. But regardless, it says “west” and “65 mph” → direction + speed → velocity.
✔ Answer: Velocity
---
11. The SUV slowed down and turned left as a gas station to get gas.
→ Slowed down (change in speed) AND turned (change in direction) → both are forms of acceleration.
✔ Answer: Acceleration
---
12. The horse ran 40 mph to win the race.
→ Only speed mentioned — no direction → speed.
✔ Answer: Speed
---
13. The train traveled west by northwest in 30 seconds.
→ “West by northwest” is a direction, but no actual speed given? Wait — it says “traveled... in 30 seconds” — but doesn’t say *how far*. Hmm.
Actually, re-read: “The train traveled west by northwest in 30 seconds.” — This is ambiguous. It doesn’t specify distance, so we can’t calculate speed. But since it mentions direction, and implies motion over time, it’s probably meant to be velocity (even if incomplete). In educational contexts, if direction is given, it’s usually velocity.
✔ Answer: Velocity
*(Note: Technically, without distance, we can’t compute velocity, but based on context and intent of the worksheet, “velocity” is expected.)*
---
14. The Olympian swam 200 meters in 30 seconds.
→ Distance and time → speed.
✔ Answer: Speed
---
15. The runner sped up to cross the finish line.
→ “Sped up” = increasing speed → acceleration.
✔ Answer: Acceleration
---
## ✔ Final Answers:

🔑 Definitions (to help you decide):
- Speed: How fast something is moving — a scalar quantity (only magnitude, no direction).
Example: “60 km/h”
- Velocity: Speed in a specific direction — a vector quantity (magnitude + direction).
Example: “60 km/h north”
- Acceleration: The rate at which velocity changes — includes speeding up, slowing down, or changing direction.
Example: “5 m/s²” or “slowing down from 20 m/s to 10 m/s”
