📌 Understanding Potential Energy
Potential energy is the stored energy an object has due to its position in a gravitational field. It is calculated using:
Potential Energy (PE) = Mass (m) × Gravity (g) × Height (h)
The unit of potential energy is **Joule (J)**.
📌 Examples of Potential Energy Calculation
| Mass (kg) | Height (m) | Gravity (m/s²) | Potential Energy (J) |
|---|---|---|---|
| 10 | 5 | 9.81 | 490.5 |
| 15 | 8 | 9.81 | 1177.2 |
| 20 | 12 | 9.81 | 2354.4 |
❓ FAQs
Q1: How do I calculate potential energy?
✅ Potential energy is calculated using the formula **PE = m × g × h**, where m is mass, g is gravity (typically 9.81 m/s²), and h is height.
Q2: What is the unit of potential energy?
✅ The unit of potential energy is the **Joule (J)**, which is equivalent to one Newton-meter (N·m).
Q3: Can potential energy be negative?
✅ Potential energy can be negative depending on the chosen reference point. If an object is below the reference level, its potential energy is negative.
Q4: Does potential energy depend on gravity?
✅ Yes, potential energy depends on gravitational acceleration, which varies slightly across different planets and altitudes.
Q5: What happens to potential energy when height increases?
✅ Potential energy increases proportionally as height increases, meaning an object gains more stored energy the higher it is positioned.
