How this calculator works
Enter the values for first value, second value and review the units before calculating.
Formula / method
KE = ½mv²
Worked example
A 10 kg object moving at 20 m/s has 2,000 J of kinetic energy.
Assumptions and limitations
The speed is well below the speed of light and mass is constant.
Relativistic effects are not included; use a relativistic model at extreme speeds.
