Energy To Momentum Calculator


Calculating energy to momentum conversions is a fundamental task in physics, especially in fields like mechanics and thermodynamics. With the right formula and tools, you can easily determine the momentum resulting from a given energy value or vice versa. In this article, we’ll explore how to use a calculator to perform these conversions efficiently.

How to Use

To use the energy to momentum calculator, simply input the known value (either energy or momentum) into the corresponding field. Then, click the “Calculate” button to obtain the result.


The formula for calculating momentum from energy (or vice versa) is:


  • p represents momentum
  • m represents mass
  • E represents energy

Example Solve

Let’s say we have an object with a mass of 5 kg and an energy of 50 J. Using the formula mentioned above, we can calculate the momentum:


Q: What units are used for energy and momentum in this calculator?

A: The energy should be provided in joules (J), and the momentum will be calculated in kilogram meters per second (kg m/s).

Q: Can this calculator handle negative energy values?

A: No, the calculator assumes positive energy values only, as negative energy doesn’t have physical significance in this context.

Q: Is there a limit to the size of the numbers that can be input?

A: The calculator can handle large numbers, but for very large or very small values, scientific notation may be more appropriate.


Using an energy to momentum calculator simplifies the process of converting between these two important physical quantities. By following the provided formula and instructions, you can quickly and accurately determine momentum from energy and vice versa, aiding in various physics calculations and analyses.
