Kinetic Energy Calculator (Ek=½mv²)

Compute kinetic energy via Ek = ½mv²: enter mass and velocity to get joules and the equivalent drop height.

Key points

Kinetic Energy Calculator (Ek=½mv²): Compute kinetic energy via Ek = ½mv²: enter mass and velocity to get joules and the equivalent drop height. Formula: Ek = ½·m·v². Enter parameters on the DD-CAT IDE online tool page to get results instantly, with a calculation-model diagram that updates with the inputs. Ek = ½mv²: kinetic energy scales with mass and with the square of velocity — doubling speed quadruples energy. Units: 1 J = 1 kg·m²/s²; collision energy grows with the square of speed, a key safety rationale for speed limits.
