Types Of Energy Kinetic

Types Of Energy Kinetic

The energy possessed by a body by virtue of its motion is called as kinetic energy and is defined technically as the work required for accelerating a body of given mass from its state of rest to motion. Kinetic energy is classified into three different forms such as:

* Vibrational

* Rotational

* Translational


Vibrational kinetic energy one among the types of energy kinetic is the energy associated with vibration of minute particles such as atoms and molecules. The technical definition of types of energy kinetic is, ‘the energy required to vibrate a body in rest’. Vibrational kinetic energy is given by the sum of total kinetic energy of an object’s molecules. Atoms or molecules can be vibrated by exciting them with heat and it can also be the other way around where vibration of atoms or molecules might release heat energy. Vibrational kinetic energy is not usually related to large objects.


The types of energy kinetic associated with rotation of a body is called as rotational kinetic energy and it is defined as the work required for forcing a body at rest to rotational motion. Our planetary motion itself is a big example for rotational kinetic energy where the planet rotates at a velocity in an axis.

The idea of rotational kinetic energy is made use of in energy generation by implementing wind turbine generators and such turbines. In all, turbine, power generators, the basic idea is the rotation of the turbine to induce an electromagnetic field, no matter what resources is used for rotating the turbine.

Wind turbines are gaining wide popularity, wherever sufficient wind is available, as wind turbine power generators are technically expense free once they are installed. Even though implementation costs are slightly higher, wind power generators, are highly considered because they are eco friendly and pose no hazard to the environment.


Among the different types of energy kinetic, translational kinetic energy is the types of energy kinetic that is associated with the translational motion of a body and is defined as the work required for changing the state of rest of a body to state of motion in the direction of the applied force. While using the term kinetic energy, we all refer to translational kinetic energy and other forms of kinetic energy are mentioned by their specific names.

It is the translational kinetic energy among the types of energy kinetic of various resources that is converted into useful work in power generation.

* In hydroelectric power station the water is made to travel through penstock pipes at high speed and this translational kinetic energy is used to rotate the turbines, which later converts the energy into useful power.

* In wind power mills, instead of water, the translational kinetic energy of wind is used to rotate the turbines and the principle of power generation remains the same as that of hydroelectric power stations.

* In nuclear power stations steam is generated by boiling water using nuclear fuel and this steam is passed at high speed and pressure on to the turbines. The translational kinetic energy of the steam is utilized in rotating the turbines and to generate power.
