Energy is a quantitative property of matter. It can be transferred from one system to another. The performance of work is a manifestation of energy. Energy can also be observed in the form of light and heat. This property makes energy a conserved quantity. It cannot be created or destroyed, but only transferred. Therefore, all forms of energy are finite. Hence, we must conserve energy. We can do this by utilizing renewable energy sources. But this can be costly as there are numerous types of energy available.
Besides being a fundamental building block of our physical universe, energy is also a concept that underlies all our everyday activities. It is everywhere we look. Everything is made up of electrons that move when a force is applied to it. Similarly, electricity comes from the chemical energy released during burning of fossil fuels. But, there is no such thing as pure energy. Energy can be divided into two categories: potential energy and kinetic energy.
There are many forms of energy. For example, in science, there is a joule, a unit of energy that is equivalent to one newton of force pushed a metre. For example, you need ten joules of energy to lift a textbook. A joule also refers to the energy associated with objects in motion. This depends on the mass and the speed of the object. This concept is often used in science.
Chemical energy is stored in molecules and atoms. Different atoms store potential energy and it depends on the positions of the atoms in these molecules. Scientists use these properties to determine the amount of energy contained in a chemical substance. Chemical energy is stored in different chemicals, with some releasing thermal energy while others releasing kinetic energy. When these two forms of energy are converted into work, they become heat. This process is called energizing.
A piece of buttered toast contains 315 kilojoules of energy. The amount of energy in such a small amount can be converted into a billiard ball. The energy in this type of food is enough to pedal a bike for ten minutes or run for six minutes. This is a great example of the power of energy. And we can see that energy can be transformed into different forms, depending on its location and purpose.
Potential energy is stored in objects at rest. This is also known as stored energy. The heavier an object is, the more potential energy it contains. Hydroelectric dams use this type of energy to produce electricity. Hydroelectric dams use water held in the reservoir to power turbines. However, when the water is released, this energy is also released. The result is a huge amount of energy. However, it is also possible to create nuclear energy through the splitting of atoms.
The mass of a palladium atom, if a neutron is added to it, is minus the mass of uranium. This is because energy is not a conservation of mass. This energy will be released into the surrounding environment, known as radiant energy. There are two main types of energy: heat and light. The former can be produced by burning uranium. But if it is stored in a metal, the heat can cause the metal to melt.
As we discussed earlier, energy can be defined as the ability of something to perform work. It can take different forms: thermal, electrical, and nuclear. The main difference between them is that potential energy happens before an action, whereas kinetic energy occurs during an action. Hence, the energy you store in a food product can be stored in a container and converted into kinetic energy when the action is carried out. Hence, kinetic energy is more efficient than potential energy.
Chemical energy is stored in food and in the human body. When you consume food, this chemical energy is converted into kinetic energy. In the same way, water flowing in a river can be converted into electrical energy. Electrical energy is then converted into heat or light. This kind of energy can be used as a primary or secondary energy source, and can be produced using renewable and nonrenewable sources.

A source of thermal energy is the sun’s radiation. It is responsible for heating food, lifting mountains, and lowering land. Moreover, it releases gravitational potential energy stored in rocks, which can then be converted into active kinetic energy during landslides. Similarly, earthquakes release elastic potential energy stored in rocks. This stored energy can be utilized in nuclear power plants. But how do we tap into this potential energy? And what can we do with it?
