ENGINEERING PRINCIPLE
Moving mass stores kinetic energy proportional to the square of velocity.
Calculate translational kinetic energy from mass and velocity.
FORMULA & VARIABLES
KE = ½ × m × v²
- KE = kinetic energy (J)
- m = mass (kg)
- v = velocity (m/s)
CALCULATION STEPS
How this result is assembled
- Convert the entered values to the SI basis required by the formula.
- Apply KE = ½ × m × v² using the current inputs.
- Present the result as 1,250 J and review the stated assumptions.
FORMULA VERIFICATION
Units, scope and reference
Reference: NIST SP 811 for unit relationships; standard classical mechanics and strength-of-materials derivations for the stated scalar relation.
Internal basis: All inputs are converted to the calculator’s SI base before the formula is evaluated.
Valid conditions: Positive finite scalar input values in the current calculator model.
Limitations: Translational motion only is included. Relativistic effects are excluded.
ASSUMPTIONS
