1. The diagram shows a cart moving freely along a track. What happens to the energy of the cart as it moves from point A to point B on the diagram?

- Diagram Description: Point A is at the top of a hill, and point B is lower down (in a valley).
- As the cart moves from A to B, it goes downhill, so its height decreases → gravitational potential energy decreases.
- Since it’s moving downhill, it gains speed → kinetic energy increases.

So, potential energy is transformed into kinetic energy.

✔ Correct Answer: B
> *Potential energy is transformed to kinetic energy.*

2. A toy robot can walk and talk and runs on batteries. Which type of energy is stored in the batteries?

- Batteries store energy through chemical reactions between substances inside them.
- This stored energy is chemical energy, which is converted into electrical energy when the battery is used.

✔ Correct Answer: A
> *Chemical*

3. Which diagram models the position of a soccer ball when it has the greatest amount of gravitational potential energy?

- Gravitational potential energy depends on height:
$$
PE = mgh
$$
So, higher the object, greater the potential energy.

- We need to find the diagram where the ball is at the highest point in its trajectory.

Looking at the options:
- A: Ball is low, near ground.
- B: Ball is high in arc — likely the peak.
- C: Ball is mid-height.

The highest point is at the top of the arc, so the diagram showing the ball at the peak of its motion has the most gravitational potential energy.

✔ Correct Answer: B

*(Note: Based on typical layout, if option B shows the ball at the apex of a curved path, that’s correct.)*

4. What forms of energy are involved in hammering a nail into wood? Select all that apply

Let’s analyze:

- Kinetic energy: The hammer is swung, so it has motion → kinetic energy.
- Sound energy: When hammer hits nail, you hear a sound → sound energy is produced.
- Thermal energy: Some energy is lost as heat due to friction and impact.
- Electrical energy: Not involved unless powered tool — but here it's manual hammering.
- Nuclear energy: No nuclear reactions involved.

So, the main energies involved are:
- Kinetic (hammer moving)
- Sound (noise during impact)
- Also, some thermal energy (not listed), but not among choices.

From given options:
- A. Kinetic ✔
- B. Electrical ✘
- C. Sound ✔
- D. Nuclear ✘

✔ Correct Answers: A and C

5. Which term describes the energy that is stored due to the height of an object above the ground?

- This is the definition of gravitational potential energy.

Examples: A book on a shelf, water behind a dam, etc.

✔ Correct Answer: C
> *Gravitational potential energy*

✔ Final Answers Summary:

1. B – Potential energy is transformed to kinetic energy
2. A – Chemical
3. B – Diagram showing ball at highest point
4. A and C – Kinetic and Sound
5. C – Gravitational potential energy
