Rock at the edge of a cliff possesses potential energy due to its elevated position.

Let's go through each of the questions in your quiz and solve them one by one, with explanations.

1. Energy due to motion is ________ energy.

Answer: D) Kinetic

✔ Explanation:
Kinetic energy is the energy an object possesses due to its motion. The faster an object moves, the more kinetic energy it has.
- Potential energy is stored energy due to position or condition.
- Friction is a force, not a type of energy.
- "Energy" is too general.

So, the correct answer is D) Kinetic.

2. _______ energy is the energy due to an object's position or condition.

Answer: A) Potential

✔ Explanation:
Potential energy is stored energy that depends on an object’s position (like height in a gravitational field) or condition (like a compressed spring).
- Kinetic energy is due to motion.
- "All of the above" is incorrect because friction isn't a form of energy in this context.
- "None of the above" is wrong because potential energy fits perfectly.

So, the correct answer is A) Potential.

3. The faster an object moves, the _____ kinetic energy it has.

Answer: A) more

✔ Explanation:
Kinetic energy increases with speed. The formula is:

> $ KE = \frac{1}{2}mv^2 $

This means kinetic energy is proportional to the square of the velocity. So, as speed increases, kinetic energy increases significantly.

Thus, the correct answer is A) more.

4. Gravitational potential energy depends on the _____ and _____ of the object.

Answer: C) Height and mass

✔ Explanation:
Gravitational potential energy is given by:

> $ GPE = mgh $

Where:
- $ m $ = mass
- $ g $ = acceleration due to gravity
- $ h $ = height

So, it depends on mass and height.

- Movement doesn’t affect GPE directly.
- Friction is unrelated to GPE (though it can dissipate energy).

Correct answer: C) Height and mass

5. Elastic potential energy is the ability to stretch or _______

Answer: B) compress

✔ Explanation:
Elastic potential energy is stored in objects that can be deformed (stretched or compressed) and then return to their original shape, like springs or rubber bands.

- "Stretch" is already mentioned in the question.
- "Compress" is the opposite action — also stores elastic energy.
- "Pull" and "straighten" are less accurate.

So, the best answer is B) compress, as it completes the idea of deformation.

6. What kind of energy is in a rock at the edge of a cliff?

Answer: A) Potential

✔ Explanation:
The rock is not moving, so it has no kinetic energy. But it is at a height above the ground, so it has gravitational potential energy due to its position in Earth’s gravitational field.

If it falls, this potential energy will convert into kinetic energy.

So, the correct answer is A) Potential.
