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 (meters per second squared, m/s²)
  • h = Height above reference point (meters, 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 meter, N/m)
  • x = Displacement from equilibrium position (meters, 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 (meters, 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 a type of energy an object has when it's in a certain position. It's like a coiled spring waiting to release its energy. The most common forms of potential energy include gravitational, elastic, and electric. Gravitational potential energy depends on height, while elastic potential energy comes from stretching or compressing materials like springs. Electric potential energy is related to charged particles and their positions relative to each Other.

What the Potential Energy Calculator Does

The Potential Energy Calculator helps you easily calculate the potential energy of different scenarios. Whether you’re dealing with heights, springs, or electric charges, this tool provides a quick and accurate way to find out how much energy is stored in an object based on its properties. You can switch between types of energy depending on your needs, making it versatile for various applications.

Types of Potential Energy You Can Calculate

This calculator offers three main types of potential energy:

  • Gravitational Potential Energy: Perfect for objects at different heights.
