1. What is Potential Energy?

Potential energy is the energy stored in an object due to its position relative to other objects. Gravitational potential energy is calculated based on an object's mass, height, and the gravitational acceleration acting upon it.

2. How Does the Calculator Work?

The calculator uses the potential energy formula:

Where:

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

Explanation: The formula 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 fundamental in physics and engineering for understanding energy conservation, mechanical systems, and designing structures.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is the standard value for gravitational acceleration?
A: On Earth's surface, the standard value is approximately 9.81 m/s², though it varies slightly with location and altitude.

Q2: Can this calculator be used for other planets?
A: Yes, simply adjust the gravitational acceleration value to match the celestial body you're calculating for.

Q3: What's the difference between potential and kinetic energy?
A: Potential energy is stored energy due to position, while kinetic energy is energy of motion.

Q4: Does potential energy depend on the path taken?
A: No, gravitational potential energy depends only on vertical displacement, not the path taken.

Q5: What is the reference point for height measurement?
A: Height is typically measured from a reference point where potential energy is defined as zero, often the lowest point in the system.
