1. What is Potential Energy?

Potential energy is the energy stored in an object due to its position relative to other objects. In the context of gravitational potential energy, it represents the energy an object possesses because of its height above a reference point.

2. How Does the Calculator Work?

The calculator uses the potential energy formula:

\[ PE = m \times g \times h \]

Where:

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

Explanation: The formula calculates the energy stored in an object based on its mass, the gravitational force acting upon it, and its height above a reference level.

3. Importance of Potential Energy Calculation

Details: Calculating potential energy is crucial in physics and engineering for understanding energy conservation, mechanical systems, and designing structures. It helps predict how much energy can be converted to kinetic energy when an object falls.

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 numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the standard value for gravity on Earth?
A: The standard gravitational acceleration on Earth 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 gravity value to match the gravitational acceleration of the specific 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 is independent of the path taken.

Q5: How is potential energy related to kinetic energy?
A: When an object falls, potential energy converts to kinetic energy. The total mechanical energy (potential + kinetic) remains constant in a conservative system.
