Kinetic energy is the energy an object possesses due to its motion. It depends on both mass and velocity — doubling the mass doubles kinetic energy, but doubling the velocity quadruples it.
Steg-för-steg-guide
- 1KE = ½mv²
- 2m = mass in kg, v = velocity in m/s
- 3KE is in joules (J)
Lösta exempel
Ingång
1 kg at 10 m/s
Resultat
50 J
½ × 1 × 100 = 50 J
Ingång
1,500 kg car at 30 m/s (108 km/h)
Resultat
675,000 J = 675 kJ
½×1500×900
