⚡ Kinetic Energy Calculator
Calculate kinetic energy, mass, or velocity using the formula KE = ½mv².
What is Kinetic Energy?
Kinetic energy is the energy of motion, defined by the formula KE = ½mv², where m is mass in kilograms and v is velocity in meters per second. The result is in Joules (J). Kinetic energy is always positive and increases with the square of velocity, meaning doubling the speed quadruples the kinetic energy.
Conservation of Energy
Kinetic energy can be converted to and from potential energy. In a closed system, the total mechanical energy (KE + PE) remains constant. This principle is fundamental in physics, from roller coasters to planetary orbits. This calculator can solve for any of the three variables: KE, mass, or velocity.
