Potential Energy Formula Calculator
Understanding energy is one of the most important concepts in physics, and potential energy plays a key role in explaining how objects store energy due to their position. Whether you are a student, teacher, engineer, or science enthusiast, calculating potential energy accurately is essential for learning and real-world applications.
Our Potential Energy Formula Calculator is designed to make this process fast, easy, and error-free. Instead of manually applying formulas and doing calculations on paper, you can now compute gravitational potential energy instantly by entering just three values: mass, gravity, and height.
This tool is perfect for physics homework, exam preparation, classroom demonstrations, and quick scientific calculations.
What Is Potential Energy?
Potential energy is the energy stored in an object because of its position or condition. In gravitational systems, an object gains potential energy when it is lifted to a certain height above the ground.
For example:
- A book placed on a shelf
- A rock held above the ground
- Water stored in a dam
All of these objects store energy due to gravity. When they fall, this stored energy converts into kinetic energy.
Gravitational Potential Energy Formula
The calculator uses the standard and widely accepted physics formula:
PE = m × g × h
Where:
- PE = Potential Energy (in joules)
- m = Mass (in kilograms)
- g = Gravitational acceleration (in m/s²)
- h = Height (in meters)
On Earth, the default value of gravity is 9.8 m/s², which is already set in the calculator for your convenience.
How to Use the Potential Energy Formula Calculator
Using this calculator is extremely simple and requires no prior technical knowledge.
Step-by-Step Instructions
- Enter Mass (kg)
Input the mass of the object in kilograms. - Enter Gravity (m/s²)
The default value is 9.8 (Earth’s gravity).
You can change it if calculating potential energy on another planet. - Enter Height (m)
Enter the height of the object above the reference point in meters. - Click “Calculate”
The calculator instantly displays the potential energy in joules. - Use “Reset” if Needed
Clear the values and perform a new calculation.
Example Calculation
Let’s understand the calculator with a real example.
Example:
- Mass = 10 kg
- Gravity = 9.8 m/s²
- Height = 5 m
Calculation:
PE = 10 × 9.8 × 5
PE = 490 Joules
This means the object has 490 J of gravitational potential energy at a height of 5 meters.
