Kinetic Energy To Light Energy, An Interesting Conversion Of Energy

How To Convert Kinetic Energy Into Light Energy?

Energy in physics can be explained as the quantitative property that needs to be transferred from one to another in order to perform work. Energy exists in various forms such as heat energy, light energy, sound energy, mechanical energy, electrical energy, gravitational energy, chemical energy and atomic or nuclear energy. Each form can be converted or changed into the other forms.

The SI unit of energy is Joule. Energy basically is a conserved quantity which can neither be created nor be destroyed as per the law of conservation of energy. Then where does the energy of an object go? Various forms of energy are actually transferred from one form to another as already mentioned.

Although there are many types of energies the two most important form of energy are kinetic energy and potential energy. The energy in moving objects is known as the kinetic energy whereas the energy possessed by or stored within an object is known as potential energy.

Transformation of energy- definition, and examples

Transformation of energy means the change of energy from one form to another. Energy changes everywhere in every field. According to the law of conservation of energies, every second some or the other energy is getting transformed into another form.This is actually good as this has got various applications in many fields.

Some unique examples of transformation of energies are given below:

  1. Blender- It transforms electrical energy into mechanical energy.
  2. Toaster-It transforms electrical energy into thermal energy.
  3. The sun- It transforms nuclear energy into different types of electromagnetic energy like gamma energy, ultraviolet, and infrared energy.
  4. Natural gas stoves- It converts chemical energy into thermal energy or heat energy, due to heating, which is used for cooking.
  5. Our body- It converts chemical energy (from the food we eat) into electrical and mechanical energy, which helps us to move.
  6. Rubbing two rocks-It converts kinetic energy into light energy and heat energy.

Can we see light?

We can’t see light, but light helps us to see objects. Just imagine a dark room. Can you see anything over there? The answer is No. This is because of the absence of light. You can only be able to see once you turn on the switches of the light source.

Isokinetic energy related to light energy?

Light energy, basically is a type of kinetic energy. Kinetic energy means the energy of motion and light is also moving. Hence light energy is also associated with motion and is kinetic in nature. The energy carried by photons or light is kinetic energy.

Light in most of the cases is closely related to heat. Conversion of kinetic energy to light is hence very easy. Bulb, for instance, when it’s switched on, a huge amount of flow of electrons starts rushing from the negative to the positive terminal. This excess flow generates heat and when this heat is beyond threshold it generates light. This flow of electrons contains kinetic energy since they are in motion, and the resistance caused by this flow generates heat and light.
