1. What is Potential Energy?

Potential Energy (PE) is the energy possessed by an object due to its position relative to other objects. In the gravitational field, it's calculated as the product of mass, gravitational acceleration, and height.

2. How Does the Calculator Work?

The calculator uses the potential energy equation:

Where:

• \( PE \) — Potential Energy (Joules)
• \( m \) — Mass of the object (kg)
• \( g \) — Gravitational acceleration (9.81 m/s² on Earth)
• \( h \) — Height above reference point (m)

Explanation: The equation shows that potential energy increases with mass, gravitational strength, and height.

3. Importance of Potential Energy Calculation

Details: Calculating potential energy is crucial in physics and engineering for understanding energy conservation, designing mechanical systems, and analyzing motion.

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 are the units of potential energy?
A: The SI unit is Joules (J), which equals kg·m²/s².

Q2: Why is g typically 9.81 m/s²?
A: This is the standard gravitational acceleration at Earth's surface. It varies slightly by location.

Q3: Can potential energy be negative?
A: Yes, if the reference point is above the object. The important quantity is the change in potential energy.

Q4: Does this formula work for all types of potential energy?
A: No, this is specifically for gravitational potential energy near Earth's surface.

Q5: How is this related to kinetic energy?
A: As an object falls, potential energy converts to kinetic energy, with the total mechanical energy remaining constant in an isolated system.
