1. What is Potential Energy?

Potential energy is the energy stored in an object due to its position relative to other objects. In this calculator, we focus on gravitational potential energy, which depends on an object's mass, height, and gravitational acceleration.

2. How Does the Calculator Work?

The calculator uses the gravitational potential energy equation:

Where:

• \( PE \) — Potential energy (Joules)
• \( m \) — Mass of the object (kg)
• \( g \) — Gravitational acceleration (m/s²)
• \( h \) — Height above reference point (m)

Explanation: The equation calculates the energy an object possesses due to its position in a gravitational field.

3. Importance of Potential Energy Calculation

Details: Calculating potential energy is essential in physics and engineering for understanding energy conservation, mechanical systems, and predicting object behavior in gravitational fields.

4. Using the Calculator

Tips: Enter mass in kilograms, gravitational acceleration in m/s² (default is Earth's gravity 9.81 m/s²), and height in meters. All values must be positive.

5. Frequently Asked Questions (FAQ)

Q1: What is the unit of potential energy?
A: Potential energy is measured in Joules (J) in the International System of Units.

Q2: Can potential energy be negative?
A: Yes, potential energy can be negative when the reference point is set above the object's position.

Q3: How does height affect potential energy?
A: Potential energy increases linearly with height - doubling the height doubles the potential energy.

Q4: What is the difference between potential and kinetic energy?
A: Potential energy is stored energy due to position, while kinetic energy is energy of motion.

Q5: Can this calculator be used for other types of potential energy?
A: This calculator specifically calculates gravitational potential energy. Other types (elastic, chemical, etc.) require different equations.
