This tool calculates the amount of energy in joules based on your input values.
Joule Calculator
Enter the required parameters into the fields. The parameters you need to provide are:
- Mass: The mass of the object in kilograms (kg).
- Velocity: The velocity of the object in meters per second (m/s).
- Height: The height above the ground in meters (m).
- Gravity: The gravitational acceleration in meters per second squared (m/s²). Default value is Earth’s gravity (9.81 m/s²).
Once you have entered the values, click on the “Calculate” button to get the results. The results are displayed in the form of Kinetic Energy, Potential Energy, and their Total Energy in joules (J).
How It Works
The formulae used in this calculator are:
- Kinetic Energy (Ek): (Ek = frac{1}{2} times text{mass} times text{velocity}^2)
- Potential Energy (Ep): (Ep = text{mass} times text{gravity} times text{height})
The total energy is the sum of kinetic and potential energy.
Limitations
The calculator assumes the following:
- The gravitational field is uniform.
- Air resistance and other frictional forces are negligible.
- The object is a point mass.
