In a digital clock, electrical energy is transformed into light energy when the LED or LCD display lights up to show the time. The electrical energy powers the circuitry of the clock which then activates the display to emit light.
In an alarm clock, electrical energy from the battery or power outlet is transformed into mechanical energy to move the clock hands or generate sound energy for the alarm.
In a mechanical clock, the potential energy stored in the wound-up spring is transformed into kinetic energy as the spring unwinds and powers the clock's movement. This kinetic energy is then converted into rotational and oscillatory motion to keep the gears and hands of the clock moving accurately.
The energy transformation that takes place is the conversion of one form of energy to another, such as kinetic energy to thermal energy, electrical energy to light energy, or chemical energy to mechanical energy. This conversion is governed by the laws of thermodynamics and is essential for all processes and activities in the universe.
When sunlight strikes a house, the energy transformation that takes place is from radiant energy (sunlight) to thermal energy (heat). The house absorbs the sunlight, which then gets converted into heat energy, warming up the interior.
In the engine of a typical train, the energy transformation that takes place involves converting the chemical energy stored in fuel (such as diesel) into mechanical energy through combustion. This mechanical energy is then used to move the train by powering the wheels.
