About this calculator
This calculator applies the classical mechanics formula KE = ½mv², where energy grows with the square of velocity — doubling speed quadruples the kinetic energy, not just doubles it. It's the same relationship that makes high-speed collisions so much more destructive than low-speed ones.
It's used by physics students solving textbook problems, automotive engineers estimating crash-impact energy for safety testing, ballistics enthusiasts calculating projectile energy, and roller-coaster designers checking that cars carry enough energy through a loop.
