This worksheet focuses on analyzing kinetic and potential energy in a roller coaster-style scenario, where a ball rolls from points A to G in a U-shaped track. The questions primarily require understanding the changes in kinetic and potential energy as the ball moves through various positions along the path.

Let's go through the key concepts and how they apply to these questions:

1. **Maximum Kinetic Energy:** This occurs at the lowest point on the track because the ball would have the highest speed there.
2. **Maximum Potential Energy:** This occurs at the highest points on the track, where the gravitational potential energy is the greatest.
3. **Kinetic Energy vs. Potential Energy Trade-off:** As the ball moves from high to low points, potential energy converts to kinetic energy, and vice versa.
4. **Small Increases/Decreases in Energy:** Small shifts in position cause incremental changes in kinetic and potential energy.

### Let's answer a few questions as examples:

1. **Maximum Kinetic Energy (Question 1)**: This should be at the lowest point, likely letter D.
2. **Maximum Potential Energy (Question 2)**: This will be at the highest point, likely letters A or G.
3. **Least Potential Energy (Question 3)**: This will again be at the lowest point, which would be D.

Would you like a more detailed walkthrough for each specific question? 

### Related Questions for Further Practice:
1. How does potential energy change as the ball moves from A to D?
2. Why is kinetic energy maximized at the lowest point on the track?
3. What happens to kinetic energy as the ball goes from point D to point G?
4. How can you calculate potential energy at each point if given height values?
5. How would friction affect the kinetic and potential energy in this scenario?

### Tip:
Remember that total mechanical energy (kinetic + potential) in a frictionless system is conserved, meaning energy is transferred between kinetic and potential forms without any loss.
