The image above represents electron kinetic energy.

To compute for electron kinetic energy, two essential parameters are needed and these parameters are **Mass (m)** and **Velocity (v).**

The formula for calculating electron kinetic energy:

eV = ^{mv²}/_{2}

Where:

eV = Electron Kinetic Energy

m = Mass

v = Velocity

Let’s solve an example;

Find the electron kinetic energy when the mass is 12 and velocity is 24.

This implies that;

m = Mass = 12

v = Velocity = 24

eV = ^{mv²}/_{2}

eV = ^{(12)(24)²}/_{2}

eV = ^{(12)(576)}/_{2}

eV = ^{(6912)}/_{2}

eV = 3456

Therefore, the **electron kinetic energy **is **3456 J.**

**Calculating the Mass when the Electron Kinetic Energy and the Velocity is Given.**

m = ^{eV x 2} / _{v2}

Where;

m = Mass

eV = Electron Kinetic Energy

v = Velocity

Let’s solve an example;

Find the mass when the electron kinetic energy is 12 and the velocity is 4.

This implies that;

eV = Electron Kinetic Energy = 12

v = Velocity = 4

m = ^{eV x 2} / _{v2}

m = ^{12 x 2} / _{42}

m = ^{24} / _{16}

m = 1.5

Therefore, the **mass **is **1.5.**
