What is an example of a gravitational energy?

Gravitational energy is the potential energy held by an object because of its high position compared to a lower position. In other words, it is energy associated with gravity or gravitational force. For example, a pen being held above a table has a higher gravitational potential than a pen sitting on the table.
A.

What is the light energy?

Light energy is the only form of energy that we can actually see directly. It is formed through chemical, radiation, and mechanical means. Light energy can also be converted into other forms of energy.
  • What are the sources of light energy?

    The sun is the most important source of light. The stars and moon are also natural forms of light. Artificial light is light made by humans, for example candles, fire and oil lamps. The electric light is now the most convenient form of artificial light.
  • What are the different sources of light?

    Natural sources of light include the sun, stars, fire, and electricity in storms. There are even some animals and plants that can create their own light, such as fireflies, jellyfish, and mushrooms. This is called bioluminescence. Artificial light is created by humans.
  • What is the formula for light energy?

    Formula: E = h f where: E = Energy of the photon (in Joules) h = Constant, actually known as Planck's constant, a really ugly number. f = frequency of the light in units of per seconds (1/seconds)
B.

What is an example of mechanical energy?

Objects have mechanical energy if they are in motion and/or if they are at some position relative to a zero potential energy position (for example, a brick held at a vertical position above the ground or zero height position). A moving car possesses mechanical energy due to its motion (kinetic energy).
  • What is an example of an chemical energy?

    Examples of matter containing chemical energy include:
    • coal - combustion reaction converts chemical energy into light and heat.
    • wood - combustion reaction converts chemical energy into light and heat.
    • petroleum - can be burned to release light and heat or changed into another form of chemical energy, such as gasoline.
  • What is an example of a heat source?

    Everyday Examples of Heat Energy
    • The biggest example of heat energy in our solar system is the sun itself.
    • When the burner of a stovetop is very hot, it is a source of heat energy.
    • Automobile fuels such as gasoline are sources of heat energy, as is the hot engine of a racecar or a school bus.
  • What is an example of an electromagnetic energy?

    Radio waves, microwaves, visible light, and x rays are all examples of electromagnetic waves that differ from each other in wavelength. These waves are also called "electromagnetic radiation" because they radiate from the electrically charged particles.
C.

What are some examples of heat energy?

The biggest example of heat energy in our solar system is the sun itself. The sun radiates heat to warm us up on the planet earth. When the burner of a stovetop is very hot, it is a source of heat energy. Conventional ovens are sources of convection heat energy, causing the food placed into it to become hot and cook.
  • What are some examples of sound energy?

    Examples of Sound Energy. Sound energy is produced when an object vibrates. The sound vibrations cause waves of pressure that travel through a medium, such as air, water, wood or metal.
  • What kind of energy is light?

    Electromagnetic energy is the same as radiation or light. This type of energy can take the form of visible light, like the light from a candle or a light bulb, or invisible waves, like radio waves, microwaves, x-rays and gamma rays.
  • What is an example of an chemical energy?

    Examples of matter containing chemical energy include:
    • coal - combustion reaction converts chemical energy into light and heat.
    • wood - combustion reaction converts chemical energy into light and heat.
    • petroleum - can be burned to release light and heat or changed into another form of chemical energy, such as gasoline.
