What is energy in science
Energy is the capacity of doing work. It is the quantitative properties that transfer from one object to another object. Its unit is joule. Energy is a conserved quantity. This means that the total energy of the system remains constant but it converts from one form to another form. For example, we convert mechanical energy to electrical energy to produce electricity. There are different types of energies that explained below.
Describe different forms of energy and examples
It is created from the vibratory motion of atoms and molecules within substances. If the particles move they possess more energy and they become hotter. It is also called heat energy.
Chemical energy is stored between the bonds of atoms or molecules. It is the energy due to which these particles hold together. This Stored chemical energy is found in food, biomass, petroleum, and natural gas.
This energy is stored in the nucleus of atoms. This energy is released when the fusion or fission process takes place. Nuclear power plants split the nucleus of uranium atoms for the production of electricity.
This energy is the movement of electrons. The flows of electrons that move through a wire are called electricity. Lightning is the main example of electrical energy.
This is also known as electromagnetic energy or light energy, radiant energy is a type of energy that travels in waves. The energy from the sun, x-rays and radio waves are the example of radiant energy.
This energy is the form of electromagnetic radiation. Light energy consists of photons, that produced when the atoms of an object is heat up. Light travels in the form of waves and this includes only that form of energy which are visible to the human eye.
Motion energy is also called mechanical energy. This energy is stored in an object; as objects move faster than more energy is stored. Wind, a flowing river, a moving car, or a person running is the example of motion energy.
Sound energy is the type of energy that produces by the motion of substances. It moves in waves form and is produced when a force makes an object or substance vibrate. There is usually less energy in sound than in all other forms of energy.
This is a form of energy which is stored in an elastic object, such as a coiled spring or a stretched elastic band. Elastic objects store energy when a force causes them to be squashed or stretched.
It is a form of energy. It is energy associated with gravitational force. In other words, the energy that holds by an object when it is in a high potential as compared to a lower potential.
