Forces and Motion multiple-choice assessment worksheet with questions on speed, velocity, and gravity.

Let's go through each question on the "Forces and Motion" multiple-choice assessment and solve them step by step.

---

1. What does motion mean?

- A. direction
- B. velocity
- C. mass
- D. how fast an object moves over a given period of time

✔ Correct Answer: D. how fast an object moves over a given period of time

> Explanation: Motion refers to the change in position of an object over time. While velocity (which includes speed and direction) is related, the best definition here is that motion involves how fast something moves over time — which describes speed or velocity, but more broadly, it's about movement with respect to time. Option D captures this idea most accurately in simple terms.

2. If a train travels 800 miles in 5 hours, what is its rate of speed?

- A. 16 mph
- B. 150 mph
- C. 160 mph
- D. 200 mph

✔ Correct Answer: C. 160 mph

> Explanation:
Speed = Distance ÷ Time
= 800 miles ÷ 5 hours = 160 mph

So, the correct answer is C. 160 mph.

3. If you say that an airplane is traveling 500 mph west, you are describing its:

- A. speed
- B. velocity
- C. direction
- D. thrust

✔ Correct Answer: B. velocity

> Explanation:
Velocity is speed with direction. Saying "500 mph west" includes both magnitude (speed) and direction, so it's a description of velocity.

4. What is a force?

- A. something that pulls
- B. something that pushes
- C. something that pulls and pushes
- D. both A and B

✔ Correct Answer: D. both A and B

> Explanation:
A force is any push or pull on an object. So it can be either a push or a pull — therefore, both A and B are correct. The best choice is D. both A and B.

---

5. The force of gravity:

- A. pushes
- B. pulls
- C. lifts
- D. none of these

✔ Correct Answer: B. pulls

> Explanation:
Gravity is an attractive force that pulls objects toward each other. For example, Earth pulls objects downward. So, gravity pulls, not pushes or lifts.

---

✔ Final Answers:

1. D
2. C
3. B
4. D
5. B
