The real definition of energy is the ability to do work. Work does not necessarily have to be a job; it could be anything from walking down the street to a battery powered lamp producing light.

# data[].attributes.body
All types of energy are constantly changing. For example, a person jogging moves by converting chemical energy stored in their body into mechanical energy, where a small portion of that will be unintentionally converted into thermal "waste" energy. Another example are solar powered lights. Radiant energy emitted by the sun enters solar panels where it is converted into electrical energy. Finally, it reaches the lamp and is converted into radiant energy once more.

Energy transfer is simply the movement of energy. During energy transfer, the energy's form is retained, otherwise it would be energy transformation. Energy transfer occurs often in everyday life. A candle lit by a lighter is a good example. The thermal energy from the lighter ignites the candle stick, and on the molecular level, some of the lighter thermal energy is being transmitted to the candle.

The Law of Conservation of Energy confirms that while energy can move or change forms, it cannot be destroyed or created, comparable to the Law of Conservation of Mass. When you use a flashlight and the light energy appears to fade away, that energy is not being destroyed. The light is either dispersing too far away from each other to be seen by the human eye or it has been changed into another form.

Mechanical energy is movement. You exert mechanical energy by doing everyday tasks, including walking, breathing, eating, and drinking.

# data[].attributes.body
Thermal energy is released as heat. Heat is created by movement in atoms. Thermal energy is sometimes considered "waste energy". For example, when you run, you utilize mechanical energy, but a small percentage is "wasted" and released as thermal energy instead.

Sound energy is a unique type of energy carried in sound waves. The waves can easily travel through gases, as well as solids and liquids, though that muffles the sound. Sound is created by vibrations which bounce of particles in the air.

Chemical Energy is stored within matters' atoms and is what keeps them together. Food and fuel contain mass amounts of potential energy in the form of chemical energy.

# data[].attributes.body
Electrical energy is carried by sub-atomic particles with negative charges called electrons. Electricity can be carried by metals such as copper, zinc, and aluminum, which are called conductive metals. Electrical energy is also called electricity.

Question 2-Can Energy be created or destroyed?

Question 2-Can Energy be created or destroyed?

# data[].attributes.body
No, energy cannot be created or destroyed. The Law of Conservation of Energy states that energy, regardless of its form, transformations, or whether it is potential or kinetic, cannot be created or destroyed. Therefore, there is a certain amount of energy in the universe, and that number cannot be raised, lowered, or changed in any way.

# data[].attributes.body
Radiant energy is energy emitted by the sun. It comes in many forms, which are part of the electro-magnetic system. Radiant energy is the start of all energy.

# data[].attributes.body
Yes, all forms of energy, whether potential or kinetic, can change into other forms indefinitely. When this happens it is called energy transformation. Throwing a ball in the air and letting it drop is an example of energy transformation. Firstly, you exert chemical energy that has been transformed into mechanical energy to hurl the ball. Next, some of the mechanical energy is changed into sound energy when the ball bounces on the ground.

Question 3-Can an object more than one type of energy

Question 3-Can an object more than one type of energy

# data[].attributes.body
Yes, an object can release multiple types of energy. Take a lamp, for instance. The lamp's job is to convert electrical energy into radiant energy. However, a small amount of the electrical energy is released as thermal energy simultaneously. This is one example of many; when humans perform physically straining activities, they exert mechanical energy, but a little bit is released as thermal energy, which can be observed as increased body temperatures after they finish.

# data[].attributes.body
Different types of energies move in different ways. Sound energy, for example, is carried by sound waves, which can move through all types of matter, though that can muffle the sound. Or, as in the picture above, chemical energy is being transferred throughout the human's body to give her strength to power the bike. It then becomes mechanical energy that flows through the object that it is propelling. After that, it turns into electrical energy that is carried by electrons, which can be channeled using conductive metals. On the final step of the journey, the energy is now radiant energy, which can be carried by visible light, as well as any other wave in the electro-magnetic system.
