First, you use the mechanical energy to power a generator. Then you use the electricity from the generator to power a light bulb. Because the filament is a resistor, it converts enough of the electricity into heat energy to cause the filament to glow.

Are you looking for the quantitative or the qualitative answer?
If you're looking for a simple answer, buy one of those flashlights that you shake. This is what's called induction. Simply put, induction is the act of moving a magnet through a coil of metal creating a flow of electrons, or current. This current can be easily converted to light by using an element that resists the flow of electricity and conversely gives off light, or by using a Light Emitting Diode (LED).
Even simpler: Light a match. You do work to provide the necessary friction and heat to ignite the chemicals on the match, and create light.

Another way - used in those flashing-light shoes made for children and more usefully in sonar and its related fields - is piezoelectricity. A piezoelectric material is one which responds to changing stress hence strain by producing a proportional potential difference (voltage) across it; but the generation occurs only while the strain is changing, and the power / volume ratio is very low.

How does mechanical energy convert to light energy?
Mechanical energy can be converted to light energy through various mechanisms, such as piezoelectric materials, which generate an electric current in response to mechanical stress. This electric current can then be used to power a light-emitting device, such as an LED, to produce light. Another common method is through mechanical motion that generates friction, heat, and ultimately light energy, as seen in friction-based fire-starting tools.
How do you convert windnergy into mechanical energy?

Is light mechanical energy?
Light is not mechanical energy but it can be transformed into mechanical energy. Light creates an impact as it hits a surface.
Into what kinds of energy does a toaster convert electrical energy?
A toaster converts electrical energy into thermal energy and radiant energy. The electrical energy is used to heat up the toaster coils, which then radiate heat to toast the bread.
What does a motor convert?
A motor converts electrical energy into mechanical energy to create motion or perform work.
The conversion of electrical energy in to mechanical energy?
Motors convert electrical energy to mechanical energy. Generators transfer mechanical energy to electrical energy.
Can television convert electrical energy to mechanical energy?
No
How can you convert chemical energy to mechanical energy?
By burning
How can you convert electrical energy to mechanical sound and heat energy?
To convert electrical energy to mechanical sound, you can use a transducer like a speaker that converts the electrical signal into vibrations that create sound waves. To convert electrical energy to heat energy, you can use resistive elements like heating coils or resistors that generate heat when electricity passes through them due to their resistance.
What are four kinds of energy that electricity can be changed into?
You can convert electrical energy into any other kind of energy.You can convert electrical energy into any other kind of energy.You can convert electrical energy into any other kind of energy.You can convert electrical energy into any other kind of energy.
How is mechanical energy conserved?
Mechanical energy is conserved in a closed system when the sum of kinetic energy and potential energy remains constant. This means that energy can change between these two forms, but the total mechanical energy remains the same. This principle is known as the conservation of mechanical energy.
Can you charge battery by mechanical energy?
No. There are, indeed, ways to convert mechanical energy into electrical energy, but a battery is not usually designed to do this. You can convert mechanical energy to electrical energy by another device, but the battery itself has to be charged by electricity.
