What is called kinetic energy? Can kinetic energy be negative?
| October 24, 2020 | Education
The physical quantity K = mv ^ 2/2 is called the kinetic energy of a material point of mass m, moving in an inertial frame of reference with a speed v. Kinetic energy cannot be negative, because the expression for the kinetic energy includes the square of the velocity, and this value is always positive.
