Kinetic Energy

Kinetic Energy is motion energy; we can also call it as motion energy. If any object is moving either vertically or horizontally, has kinetic energy.  The elements of the object that helps in moving the object like – atoms, waves, molecules and atoms, these elements are the crucial cause of movement.  Any object, which moves, is an example of kinetic energy, there are some significant examples of kinetic energy like – a football has kinetic energy because the player kicks it and it moves, a meteor have kinetic energy, bullet posses’ kinetic energy because it has been shot from a gun and it moves forward.

Kinetic energy is helpful energy because the energy that is produced can be used by itself. There are ample of uses of kinetic energy because it can be converted in many forms of energy like – potential energy, heat energy, sometimes it can be converted into sound and lights energy.

Kinetic energy has three forms, which are mentioned beneath –

  • Vibrational energy –

This energy is produced when there is any type of vibration in object or object is experiencing any vibrational movement.  The best example of this energy vibrational energy is the cell phones, when any one calls you then there is a slight movement in phone and thus the energy, which is produced, called as kinetic vibrational energy.

  • Kinetic rational energy –

This energy is produced when there is any rational motion or movement occurs in an object.  The finest example of this energy is a moving bicycle wheel.  Another example of kinetic rational energy is the earth because it also moves on its axis.

  • Translational kinetic energy –

This energy is the common energy, which is known by everyone. This energy is produced when an object moves from its initial position to another one. Football is the perfect example of this energy because when football is kicked it moves and thus translational energy is produced.

The amount of kinetic energy depends on the weight of an object, and what is the speed of an object when it was moving. If the mass of an object is large then its, speed will be great and it has more kinetic energy. We can also explain this in other words that slow and light object in weights will have less amount of kinetic energy while heavy and fast moving object has more kinetic energy.


The kinetic energy is represented by this equation –

KE = ½ *m * v2


In the above equation, m stands for mass of an object and v stands for speed of an object.


Any object having greater speed has more kinetic energy, body posses this energy because of its motion. Hammer is also a unique example of kinetic energy because when it strikes on nail, nails moves inside in wood, hence kinetic energy produces. When we stroke at the hammer it create some motion and that motion leads to kinetic energy. Angular and linear motion both produces kinetic energy.
