Potential energy is the energy stored in an object due to its position relative to some reference point. The most common types are gravitational potential energy and elastic potential energy.

This calculator helps you determine potential energy using different methods based on the physical situation.

About Potential Energy

Potential energy is the energy an object possesses due to its position or state, rather than its motion. It's energy that is stored in an object and has the potential to be converted into other forms of energy.

Gravitational Potential Energy:

The energy stored in an object due to its height above a reference point in a gravitational field.

  • Formula: PE = m × g × h
  • Where:
  • PE = Gravitational potential energy (joules, J)
  • m = Mass (kilograms, kg)
  • g = Gravitational acceleration (metres per second squared, m/s²)
  • h = Height above reference point (metres, m)
Elastic Potential Energy:

The energy stored in elastic materials when they are stretched or compressed.

  • Formula: PE = ½ × k × x²
  • Where:
  • PE = Elastic potential energy (joules, J)
  • k = Spring constant (newtons per metre, N/m)
  • x = Displacement from equilibrium position (metres, m)
Electric Potential Energy:

The energy stored in a system of charged particles due to their positions relative to each other.

  • Formula: PE = k × q₁ × q₂ / r
  • Where:
  • PE = Electric potential energy (joules, J)
  • k = Coulomb's constant (8.99 × 10⁹ N·m²/C²)
  • q₁, q₂ = Electric charges (coulombs, C)
  • r = Distance between charges (metres, m)
  • ε = Permittivity of medium (F/m)
Applications of Potential Energy:
  • Gravitational: Hydroelectric power, pendulums, roller coasters
  • Elastic: Springs, bungee cords, bow and arrow
  • Electric: Batteries, capacitors, atomic bonds
Energy Conversion:

Potential energy can be converted to kinetic energy (energy of motion) and vice versa. The Law of Conservation of Energy states that energy cannot be created or destroyed, only converted from one form to another.

Understanding Potential Energy

Potential energy is the energy stored in an object because of its position or state. This energy depends on its height, shape, or electric charge. The most common types are gravitational potential energy, elastic potential energy, and electric potential energy. Each type can be calculated using specific formulas, making it essential to understand the context of your calculations. With our tool, you can easily measure the potential energy for various situations.

What the Potential Energy Calculator Offers

This calculator is designed to help you find potential energy quickly and accurately. You can choose from different energy types, including:

  • Gravitational Potential Energy
  • Elastic Potential Energy
  • Electric Potential Energy

Depending on your selection, the required inputs will change, allowing for a tailored experience that fits your needs.

Calculating Gravitational Potential Energy

Gravitational potential energy is calculated based on an object's mass, height, and the gravitational pull at its location. The formula used is PE = m × g × h, where 'm' is mass in kilograms, 'g' is gravitational acceleration, and 'h' is height in metres. The calculator allows you to input these values easily, even letting you select from different planets for accurate gravitational values.

Exploring Elastic Potential Energy

Elastic potential energy is found in objects that can stretch or compress, like springs. To calculate this energy, the formula used is PE = ½ × k × x², where 'k' is the spring constant and 'x' is the displacement from its normal position. The calculator lets you enter the spring constant and displacement, so you can find the energy stored in the spring when it is deformed.

Understanding Electric Potential Energy

Electric potential energy is the energy between charged particles. The calculation involves the charges and the distance between them, using the formula PE = k × q₁ × q₂ / r. In this case, 'q₁' and 'q₂' are the charges, 'r' is the distance, and 'k' is Coulomb's constant. The calculator provides fields for these inputs, making it simple to compute the energy stored in electric systems.

Choosing the Right Measurement Units

When using the potential energy calculator, you can select from various measurement units. Whether you need kilograms, grams, or pounds for mass, metres, centimetres, or feet for height, the choices are there for you. This flexibility helps ensure you get accurate readings in the units you're most comfortable with.

Visualising Energy Calculations

The calculator doesn't stop at just providing numbers. It also features visual aids to help you understand your results better. You'll find charts that show how potential energy changes with different parameters. This visual representation makes it easier to grasp the concepts behind potential energy and how various factors influence it.
