Step-by-step solution for: Potential and Kinetic Energy
Let's solve and explain each section of the worksheet step by step. This worksheet focuses on the Law of Conservation of Energy, energy transfer, energy transformation, and applies these concepts to a roller coaster scenario.
---
- Energy can be neither created nor destroyed by ordinary means.
→ *This is the core idea of the conservation of energy.*
- Energy can be transformed from one form to another.
→ *Energy changes forms, but it doesn't disappear or appear out of nowhere.*
- The total amount of energy is the same before and after any energy transformation.
→ *Total energy in a closed system remains constant.*
✔ Completed:
> - Energy can be neither created nor destroyed by ordinary means.
> - Energy can be transformed from one form to another.
> - The total amount of energy is the same before and after any energy transformation.
---
> Energy TRANSFER is the movement of energy from one object to another object.
Example: A cup of hot tea has thermal energy. Some of this thermal energy is transferred to the particles in cold milk, in which you put to make the coffee cooler.
✔ Completed:
> - Energy TRANSFER is the transfer (or movement) of energy from one object to another object.
> - Example: A cup of hot tea has thermal energy. Some of this thermal energy is transferred to the particles in cold milk...
---
> ✔ A change from one form of energy to another.
#### Single Transformations
- Occur when one form of energy needs to be changed into another to get work done.
✔ Completed:
> - Occur when one form of energy needs to be changed into another to get work done.
#### Multiple Transformations
- Occur when a series of energy transformations are needed to do work.
- An object’s energy can be:
- As velocity increases, kinetic energy increases and potential energy decreases.
- As velocity decreases, kinetic energy decreases and potential energy increases.
✔ Completed:
> - Occur when a series of energy transformations are needed to do work
> - As velocity increases, kinetic energy increases and potential energy decreases
> - As velocity decreases, kinetic energy decreases and potential energy increases

→ Kinetic Energy (KE) and Gravitational Potential Energy (PE) have an inverse relationship in conservative systems like roller coasters.
When one increases, the other decreases — but their total remains constant (assuming no friction or air resistance).
✔ Answer:
> KE and PE have an inverse relationship: as one increases, the other decreases, and their sum remains constant.

Now let's analyze the roller coaster diagram and fill in the blanks.
1. As you move up to the first hill on a roller coaster, the distance between the coaster and the Earth increases, resulting in an increase of gravitational potential energy (GPE).
2. At the top of the first hill you have the maximum Gravitational Potential Energy.
3. As you begin your trip down the hill you increase your speed, resulting in a transformation from potential energy to kinetic energy.
4. At the bottom of the hill right before it goes back upward, the kinetic energy is at its maximum, but the potential energy is at its minimum.
5. As it starts to move up the next hill or loop, KE is transformed back into GPE.
✔ Completed Answers:
> - As you move up to the first hill... the distance between the coaster and the Earth increases, resulting in an increase of gravitational potential energy.
> - At the top of the first hill you have the maximum Gravitational Potential Energy.
> - As you begin your trip down the hill you increase your speed, resulting in a transformation from potential energy to kinetic energy.

| Concept | Explanation |
|--------|-------------|
| Conservation of Energy | Total energy in a closed system stays constant; energy cannot be created or destroyed. |
| Energy Transfer | Movement of energy between objects (e.g., heat from tea to milk). |
| Energy Transformation | Change from one form to another (e.g., GPE → KE). |
| KE & PE Relationship | Inverse: When height increases, GPE ↑, KE ↓; when speed increases, KE ↑, GPE ↓. |
| Roller Coaster | Demonstrates continuous transformation between GPE and KE. |

🔷 Roller Coasters – Does energy get transferred or transformed?
Now let's analyze the roller coaster diagram and fill in the blanks.
1. As you move up to the first hill on a roller coaster, the distance between the coaster and the Earth increases, resulting in an increase of gravitational potential energy (GPE).
2. At the top of the first hill you have the maximum Gravitational Potential Energy.
3. As you begin your trip down the hill you increase your speed, resulting in a transformation from potential energy to kinetic energy.
4. At the bottom of the hill right before it goes back upward, the kinetic energy is at its maximum, but the potential energy is at its minimum.
5. As it starts to move up the next hill or loop, KE is transformed back into GPE.
✔ Completed Answers:
