Kinetic Energy Formula

Aussi connu sous le nom: KE Formula

KE = \frac{1}{2}mv^2
KE = ½mv²

Ce qu'il calcule

The energy an object possesses due to its motion. Doubling the speed quadruples the kinetic energy.

variables

KEKinetic EnergyEnergy of motion
mMassMass of the moving object
vVelocitySpeed of the object

Exemples travaillés

1KE = ½ × 1500 × 20²
2KE = 750 × 400 = 300,000 J = 300 kJ
Résultat: 300 kJ

Erreurs courantes

Energy scales with v², so small speed increases have big energy impacts
Use consistent SI units (kg, m/s)
