Calculation
Eₖ = ½ · m · v²
Speed enters quadratically: doubling speed gives four times the energy.
Eₖ = ½mv²

Result
Select a target and calculate.
Understand the inputs
- Kinetic energy Eₖ — Energy of translational motion.
- Mass m — Total moving mass.
- Speed v — Speed magnitude.
Example
100 kg at 15.81 m/s have about 12.5 kJ.
Assumptions and limits
Point mass or pure translation; rotation is excluded.
