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.

2. How Does the Calculator Work?

The calculator uses the potential energy formula:

Where:

• \( PE \) — Potential energy (Joules)
• \( m \) — Mass (kilograms)
• \( g \) — Gravitational acceleration (m/s², typically 9.81 on Earth)
• \( h \) — Height (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 essential in physics, engineering, and various applications including mechanical systems, energy storage, and understanding gravitational interactions.

4. Using the Calculator

Tips: Enter mass in kilograms, gravitational acceleration in m/s² (9.81 for Earth), 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 depending on location.

Q2: Can this formula be used on other planets?
A: Yes, but you need to use the specific gravitational acceleration value for that planet or celestial body.

Q3: What are the units for potential energy?
A: Potential energy is measured in Joules (J) in the International System of Units.

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

Q5: How is potential energy related to kinetic energy?
A: Potential energy can be converted to kinetic energy when an object falls, following the principle of conservation of energy.
