Input (English): A system's Lagrangian (lah-GRAN-jee-uhn) equals this quantity minus potential energy. This quantity can be found by dividing the square of an objects momentum by twice its mass. The change in this quantity for an object is equal to the net work done on the object. It equals one-half times mass times velocity squared. For 10 points, name this type of energy that objects possess because of motion.
Output (English): Science
