1. Identify the key concepts: Kinetic energy (KE) and potential energy (PE).
2. Recall the formulas:
- KE = 0.5 × m × v²
- PE = m × g × h
3. Understand the relationships:
- Kinetic energy depends on mass and velocity.
- Potential energy depends on mass, height, and gravity.
4. Analyze the scenarios:
- A roller coaster has maximum potential energy at the highest point.
- A roller coaster has maximum kinetic energy at the lowest point.
- Potential energy decreases as the roller coaster descends.
- Kinetic energy increases as the roller coaster descends.
5. Apply the formulas to calculate specific values:
- For KE: Use mass and velocity.
- For PE: Use mass, height, and gravity (g = 9.8 m/s²).
6. Compare energy levels at different points:
- Higher height means more potential energy.
- Higher speed means more kinetic energy.
7. Answer the questions based on the analysis and calculations.
