Question
Direction : Identify the energy in each of the case.
Sun
- Potential
- Chemical
- light
- Sound
Hint:
Light
The correct answer is: light
Light energy in given by things like stars, light bulb, lasers and hot objects. Our Sun which is also a star transmits light energy to earth. The sun is a natural source of light energy. Sun radiates light and heat, or solar energy, which makes it possible for life to exist on earth.

Which type of energy is produced when the handle of a pencil sharpener turns?
¶Potential and kinetic energy sources from which mechanical energy is generated by converting them into power. Turbines powered by steam, water, wind, gas, or liquid fuels are a few examples of this.
¶Before being employed as power, machines were frequently used to convert various energy sources. We can use mechanical energy any way we want or need it to function once it has been altered in a specific way. E.g., A tool that works by using mechanical energy is a hammer. A hammer's ability to exert force on a nail to move it is made possible by the mechanical energy it possesses. The hammer can function on the nail because it possesses mechanical energy (kinetic energy). Work-enabling energy is known as mechanical energy.
