Show What You Know
Consider the diagram of changes in kinetic and potential energy of a roller coaster as it moves up and down its track.
Draw a simple graph. Label the horizontal (x) axis “Time” and label the vertical (y) axis “Kinetic energy.” Do not include units, as you will be plotting only general increases and decreases.
Use this blank graph for activity A below.
Source: Oxford Designers & Illustrators Ltd/Pearson Education Ltd
On the graph, draw a curve showing the changes in the kinetic energy of the roller coaster pictured in the illustration, starting at the point where the cars are pictured. (Hint: The kinetic energy increases when potential energy decreases because the potential energy converts to kinetic energy.)
How does your graph compare to the illustration of the roller coaster?

### Part 2: Evaluate Your Electromagnet’s Performance
#### Data Analysis and Questions
- The average for each of the three trials has been calculated and recorded in the provided tables.
- The coil configuration that served as the control during this experiment was the 30-turn coil without a core. It was important to use a control to provide a baseline for comparison against the changes made (adding turns, using an iron core, or doubling the current).
- Ranking in column 4 indicates the strength of changes:
- Iron Core with double current (most powerful)
- Iron Core (next most powerful)
- 60-turn coil (moderate strength)
- 30-turn coil (baseline, least powerful)
**Based on the rankings**, changing the core to iron and increasing the battery count yielded the most significant electromagnet strength.
#### Design for the Best Electromagnet
To create the strongest electromagnet:
- Use thinner wire for more turns if space allows.
- Use a significantly longer iron core.
- Ensure the wire is tightly wound with minimal gaps.
- Use multiple power sources in parallel for increased current.
*Insert diagram here with clear labels for wire, iron core, batteries, and other important components.*
### Part 3: Show What You Know
#### Graph for Kinetic Energy Changes
- [Graph to be drawn here]
- Kinetic energy will rise as potential energy lowers when the roller coaster descends.
**Comparison:**
Your graph should mimic the changes of the roller coaster's movement, with marked increases during drops and decreases when climbing.
#### Energy Conversion Examples
1. A toaster converts electrical energy into thermal energy.
2. Solar panels convert solar energy into electrical energy.
3. A car engine converts chemical energy from fuel into mechanical energy.
### Part 4: Reflect
1. **Performance Assessment**: I assessed my electromagnet's performance by measuring the number of paper clips picked up in varying configurations. Improvements were made by using an iron core and increasing coil turns.
2. **Difficult Steps**: The most challenging aspect was ensuring consistent coil winding and stable connections to the power source to avoid fluctuations in performance.
3. **Alternative Designs**: There are various designs; for instance, changing wire gauge or using stronger power sources could yield different results, and modifications in core material can provide unique insights into electromagnet strength.
