Enter the change in mass into the calculator to determine the binding energy of a nucleus.

## Binding Energy Formula

The following formula is used to calculate a binding energy.

E = ^M*c^{2 }

- Where E is the binding energy
- ^M is the change in mass of the reaction
- c is the speed of light (299,792,458 m/s)

## Binding Energy Definition

Binding energy is defined as the energy required to combine two atoms into a single atom.

## Binding Energy Example

How to calculate a binding energy?

**First, determine the mass defect.**Calculate the change in mass of the process. For this example, we will say the change in mass is 3.3435*10^-27 kg

**Next, determine the speed of light.**We know this value to be 299,792,458 m/s.

**Finally, calculate the binding energy.**Using the formula we find the biding energy to be 3.0048e^-10.

## FAQ

**What is a binding energy?**

Binding energy is a term used in physics to describe the required energy to combine atoms into new nuclei during nuclear fusion.

**What is mass defect?**

A mass defect is a measure of the mass lost during the combination of nuclei in nuclear fusion. This mass defect is also considered the change in mass.
