Potential Energy Calculator
Potential energy is a fundamental concept in physics and engineering, often defined as the energy an object holds or owns due to its position, state, height, or configuration. This concept is crucial not only in scientific fields but also in practical applications, like calculating the energy requirements for machinery or understanding the dynamics of moving objects.
Our potential energy calculator simplifies the calculation process, providing quick and accurate results without the need for complex formulas or manual calculations.
Whether you’re a student, scientist, or engineer, using this potential energy calculator can help you get your calculations easily. From lifting objects to analyzing gravitational forces, potential energy plays a central role, and our calculator provides a reliable solution to compute it with ease.
What Actually is Potential Energy?
Potential energy is the energy stored within an object due to its position, arrangement, height, or state. This energy is “potential” because it is not actively in motion; instead, it has the potential to become kinetic or active under the right conditions.
Objects gain potential energy when influenced by forces such as gravity, elasticity, or chemical composition. For example, A rock held above the ground has gravitational potential energy due to its position in the earth’s gravitational field.
Types Of Potential Energy
There are different types of potential energy depending on the force involved.
- Gravitational potential energy is due to the height of an object.
- Elastic potential energy is associated with stretched or compressed materials like springs or rubber bands.
- Chemical potential energy is stored in the bonds of atoms and molecules, which is released during chemical reactions.
- Electrical Potential Energy is the energy stored in electric charges due to their positions in an electric field.
By using a potential energy calculator, you can quickly determine the amount of potential energy in a given scenario, simplifying the learning and application of this concept. This tool can be particularly helpful for students and professionals who need to calculate potential energy across various physics-related fields.
Potential Energy (P.E) Formula
The formula for calculating potential energy primarily involves gravitational force. The most commonly used formula is:
P.E = m × g × h
Where:
- P.E = Potential Energy (in joules, J)
- m = Mass of the object (in kilograms, kg)
- g = Gravitational acceleration (9.81 m/s² on Earth)
- h = Height of the object from the reference point (in meters, m)
This formula applies to gravitational potential energy, where mass and height are critical factors. The higher the object or the greater the mass, the more potential energy it has due to gravity.
For other types of potential energy, such as elastic potential energy, different formulas are used, but they also incorporate the object’s properties and the force exerted.
Knowing this formula can assist you in performing manual calculations for gravitational potential energy. However, with the potential energy calculator, these calculations become swift and straightforward, providing immediate results without the risk of manual errors.
How to Use Potential Energy Calculator Correctly?

To measure Potentential Energy you have to choose Potential Energy from the dropdown as shown in the image.
2. Enter The Mass (m)
Now it’s turn to enter the correct value of mass in the Potential Energy Calculator. With the field of mass, there is a dropdown of units for mass as shown in the image. You must have to choose your desired unit in which mass of the object is measured. You can put mass value in these units: kg, g, lb, oz, ton. Make sure the value of mass is correct.
3. Enter The Height (h)
After entering mass in its desired field, Now you have to enter the correct value of height in the next field shown in the image below. Over there, there is also a dropdown for the units of height you have to choose. You can input height in these units: m, cm, mm, ft, in. Make sure the value of height is correct and you have also chosen the correct unit for height from the dropdown.
4. Confirm Gravitational Constant/Gravity (g)
At the end, there is a field for Gravity which is also known as the Gravitational Constant (g). It is already filled as 9.81 m/s² as this is the value of gravity on the surface of Earth. You may change if you are finding Potential Energy in other conditions or other place than Earth. With the field of Gravity, there is also a dropdown for units of Gravity. You can use these units for Gravity: m/s², ft/s², cm/s².
5. Calculate The Result
After entering all the values in there desired fields, you have to press Calculate button (in purple colour) to calculate the final value of Potential Energy as shown in image below.

Example Calculation Of Potential Energy
Let’s go through a step-by-step example to illustrate how to calculate potential energy manually. This will provide clarity on using the formula with real-world values. Suppose we have a 10 kg object positioned 5 meters above the ground. We’ll calculate its gravitational potential energy.
Using the formula:
PE = m × g × h
Given values:
- Mass (m) = 10 kg
- Gravitational acceleration (g) = 9.81 m/s²
- Height (h) = 5 m
Calculation:
PE = 10 × 9.81 × 5
PE = 490.5 J
So, the potential energy of the object is 490.5 Joules. This example demonstrates how straightforward the calculation is when using consistent units. However, for multiple objects or complex scenarios, a potential energy calculator simplifies the process, allowing users to perform repeated calculations with ease.
FAQs
Potential energy is the energy stored within an object due to its position, height, or state. For example, a rock held at a height has potential energy because, if released, it will fall due to gravity.
Potential energy primarily depends on three factors: the object’s mass, the height or distance from a reference point, and the gravitational force (for gravitational potential energy). The greater the mass and height, the higher the potential energy.
Joules (J) is the SI unit for all types of energy, including potential energy. This standard unit allows for consistency and comparability across different forms of energy and scientific disciplines.
A potential energy calculator applies the formula PE = m × g × h, by taking the mass, height, and gravitational force as inputs and then outputs the potential energy value in joules, kilojoules, ft-lb, and cal. This automated tool makes it easy to calculate potential energy quickly and accurately.
Yes, potential energy can be negative depending on the reference point chosen. For example, if the reference point is above the object’s position, the calculated potential energy may be negative, indicating a position below the reference point.
This potential energy calculator saves time, reduces manual calculation errors, and provides a quick way to determine potential energy for various objects. It’s especially useful for students and professionals who need to make frequent calculations.
Yes, the main types include gravitational, elastic, and chemical potential energy. Each type is defined by the specific forces or interactions that create the stored energy within the object.
Ensure that all inputs, such as mass and height, are accurate and in the correct units (e.g., kg for mass, m for height). Double-check the gravitational constant if using a different planetary setting or environment.
