This video tutorial lesson explains the meaning of kinetic energy and discusses how to determine if an object possesses kinetic energy. The kinetic energy formula is presented and its various uses are discussed.
The kinetic energy of a particle is a single quantity, but the kinetic energy of a system of particles can sometimes be divided into various types, depending on the system and its motion. For example: If all the particles in a system have the same velocity, the system is undergoing translational motion and has translational kinetic energy.
When you have objects in motion, you have kinetic energy. When, for example, you slide an object on a frictionless surface, the work you do goes into the object’s kinetic energy: W = KEf – KEi. If you have an object with mass m moving at speed v, its kinetic energy is. That’s the energy of motion.
25 mar 2021 · In physics, kinetic energy is the energy an object has due to its motion. It is defined as the work required to accelerate a body of a given mass from rest to a certain velocity. Once the mass reaches the velocity, its kinetic energy remains unchanged unless its speed changes.
