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 using the formula E = m × g × h, where m is mass, g is gravitational acceleration, and h is height.

2. How Does The Calculator Work?

The calculator uses the potential energy formula:

Where:

• \( E \) — Potential energy (Joules)
• \( m \) — Mass (kilograms)
• \( g \) — Gravitational acceleration (9.81 m/s² on Earth)
• \( h \) — Height (meters)

Explanation: This 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 essential in physics, engineering, and various applications including hydroelectric power generation, construction, and mechanical systems design.

4. Using The Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is the standard value for gravitational acceleration?
A: On Earth, the standard value is approximately 9.81 m/s², though it varies slightly depending on 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 units should I use for accurate results?
A: For the formula to work correctly, use kilograms for mass, meters for height, and m/s² for gravitational acceleration.

Q4: How is potential energy related to kinetic energy?
A: As an object falls, its potential energy converts to kinetic energy. The total mechanical energy (potential + kinetic) remains constant in a closed system.

Q5: Why is potential energy measured in Joules?
A: The Joule is the standard unit of energy in the International System of Units (SI), representing the work done by a force of one newton over one meter.
