Let's address the questions step by step, filling in the blanks and providing explanations where necessary.

1. **Moving objects have (potential or kinetic) energy.**
   - **Answer:** Kinetic
   - **Explanation:** Kinetic energy is the energy of motion. Objects that are moving possess kinetic energy.

2. **If you decrease the height of an object, the potential energy will (increase or decrease).**
   - **Answer:** Decrease
   - **Explanation:** Potential energy is related to the height of an object above a reference point (usually the ground). Lowering the height reduces the potential energy.

3. **Kinetic energy depends on an object's mass and (height or velocity).**
   - **Answer:** Velocity
   - **Explanation:** Kinetic energy is calculated using the formula $$ KE = \frac{1}{2}mv^2 $$, where $$ m $$ is mass and $$ v $$ is velocity. It does not depend on height.

4. **An increase in the velocity of an object will mean a (increase or decrease) in kinetic energy.**
   - **Answer:** Increase
   - **Explanation:** Since kinetic energy is proportional to the square of the velocity, increasing the velocity will result in a greater kinetic energy.

5. **Objects raised above the ground have (potential or kinetic) energy.**
   - **Answer:** Potential
   - **Explanation:** Objects that are elevated above the ground have gravitational potential energy due to their position.

6. **"Energy cannot be $$ 	ext{created} $$ or $$ 	ext{destroyed} $$ only $$ 	ext{transformed} $$."**
   - **Explanation:** This statement reflects the law of conservation of energy, which states that energy can change forms but cannot be created or destroyed.

7. **Rank the positions on the roller coaster from most potential energy to least potential energy.**
   - **Explanation:** To rank the positions, we would typically consider the height of each position on the roller coaster. The highest point would have the most potential energy, and as you go down, the potential energy decreases.

8. **Rank the positions on the roller coaster from most kinetic energy to least kinetic energy.**
   - **Explanation:** Kinetic energy is highest at the lowest points of the roller coaster where the speed is greatest and decreases as the coaster ascends to higher points where the speed is lower.

If you have specific positions or heights for the roller coaster, please provide them, and I can help you rank them accordingly!
1. Moving objects have **kinetic** energy. 2. If you decrease the height of an object, the potential energy will **decrease**. 3. Kinetic energy depends on an object's mass and **velocity**. 4. An increase in the velocity of an object will mean a **increase** in kinetic energy. 5. Objects raised above the ground have **potential** energy. 6. "Energy cannot be **created** or **destroyed** only **transformed**." 7. The roller coaster positions, from most potential energy to least: **Top of the highest hill**, **Middle hills**, **Bottom of the lowest hill**. 8. The roller coaster positions, from most kinetic energy to least: **Bottom of the lowest hill**, **Middle hills**, **Top of the highest hill**.
