In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.The same amount of work is done by the body when decelerating from its current ...
Kinetic energy, form of energy that an object or a particle has by reason of its motion. If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy. Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass.
Kinetic energy is the energy of motion. An object that has motion - whether it is vertical or horizontal motion - has kinetic energy. There are many forms of kinetic energy - vibrational (the energy due to vibrational motion), rotational (the energy due to rotational motion), and translational (the energy due to motion from one location to another).
Kinetic energy is the energy of mass in motion. The kinetic energy of an object is the energy it has because of its motion. For example, in order to lift a heavy object, we must do work to ...
Kinetic energy definition is - energy associated with motion. Recent Examples on the Web. What is the kinetic energy of the spacecraft at the end of the rocket burn? — Rhett Allain, WIRED, "How Fast Do Spacecraft Travel in The Expanse?," 31 May 2018 But the gifted Met orchestra of today lacks presence, depth of tone, kinetic energy. ...

Overview. Energy can neither be created nor destroyed, this is the conservation of energy law. However, energy can be altered from one form to another. All forms of energy are either potential or kinetic energy. Potential refers to stored energy while kinetic is energy in motion.
The energy possessed by a system or object as a result of its motion. The kinetic energy of objects with mass is dependent upon the velocity and mass of the object, while the energy of waves depends on their velocity, frequency, and amplitude, as well as the density of the medium if there is one (as with ocean waves). Compare potential energy.
kinetic energy A bowling ball has kinetic energy when it is moving. When it strikes the pins, some of that energy is passed on to the pins. kinetic energy n. The energy possessed by a body because of its motion, equal to one half the mass of the body times the square of its velocity. kinetic energy n (General Physics) the energy of motion of a body ...
Kinetic energy definition. The encyclopedia provides the following definition of kinetic energy: The kinetic energy of an object is the energy that it possesses due to its motion.It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.
