Examples of Kinetic Energy Examples of Kinetic Energy Kinetic energy is the energy of movement. The higher the velocity or speed, of an object, the more its kinetic energy. The heavier the object (its mass), the higher its kinetic energy. Examples of kinetic energy :1. A moving car ; 2. a moving ball ; 3. a river flowing ; 4. a plane in flight ; 5. an athlete running ; 6. a satellite in orbit ; 7. the flying object to wack one's hand or rear ; Anything that you can think of, that is moving, has kinetic energy. Other forms of energy is energy of height (potential energy), and heat energy. There are more. Energy can not be made or destroyed. It can only go from one form into another form. When the teacher chase you in mean mode, you run by using your body's chemical energy to become kinetic energy of movement.

Kinetic energy is the extra energy an object possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its current velocity. Don't confuse it for acceleration or momentum though. Kinetic energy causes acceleration and acceleration causes momentum. A cyclist will use chemical energy that was provided by food to accelerate a bicycle to a chosen speed. This speed can be maintained without further work, except to overcome airresistance and friction. The energy has been converted into the energy of motion, known as kinetic energy but the process is not completely efficient and heat is also produced within the cyclist.The kinetic energy in the moving bicycle and the cyclist can be converted to other forms. For example, the cyclist could encounter a hill just high enough to coast up, so that the bicycle comes to a complete halt at the top. The kinetic energy has now largely been converted to gravitational potential energy that can be released by freewheeling down the other side of the hill. (Since the bicycle lost some of its energy to friction, it will never regain all of its speed without further pedaling. Note that the energy is not destroyed; it has only been converted to another form by friction.) Alternatively the cyclist could connect a dynamo to one of the wheels and also generate some electrical energy on the descent. The bicycle would be traveling more slowly at the bottom of the hill because some of the energy has been diverted into making electrical power. Another possibility would be for the cyclist to apply the brakes, in which case the kinetic energy would be dissipated through friction as heat energy. Kinetic energy is the energy of motion, and is defined as mass times velocity. Evidence of kinetic energy include Examples of: Orbital motion: moons about the planets, or the planets around the sun. The motion of the stars in a galaxy, orbiting satellites and space vehicles. Random linear motion: On a molecular level, vibrations of molecules, gas molecules bouncing around a room. Rotational or torquing motion: spinning flywheels, rolling balls or wheels Projectile (parabolic) motion: a fired bullet, a thrown ball, a boy jumping Linear motion: running, bowling, aircraft in flight, a moving car or train, a boy skateboarding

Kinetic energy is the energy of motion. It is also referred to as energy in motion, or as the work required to take an object from being at rest to action/movement. Mathematically, kinetic energy is calculated as ½ of the mass of a body, multiplied by the speed of the body squared, KE=1/2 mv^2. Where Did the Kinetic Energy Term Originate? The term originated with the Greek words kinesis (motion) and energeia (active work). Put together, the two words translate to “Through motion do active work.â€? More simply, any thing, body, object, etc that has mass and is moving has some type of kinetic energy. How is Energy Transferred? One of the underlying concepts behind kinetic energy is understanding how work transfers energy from one form to another. When a mass or body is not moving, (at rest) it is considered to have potential energy. When force or work is applied to this object, the potential energy becomes kinetic. Once transferred, the kinetic energy of an object may be converted to other forms such as potential, gravitational, or elastic energy. What Are the Types of Kinetic Energy? There are two types of kinetic energy, translational and rotational. Translational kinetic energy is contained or possessed by a body that is undergoing straight-line motion. Rotational kinetic energy is energy contained in a rotating object.
