How many energies are there

Also known as light energy or electromagnetic energy, radiant energy is a type of kinetic energy that travels in waves. Examples include the energy from the sun, x-rays, and radio waves. Light energy is a form of electromagnetic radiation. Light consists of photons, which are produced when an object's atoms heat up. Light travels in waves and is the only form of energy visible to the human eye. Motion energy — or mechanical energy — is the energy stored in objects; as objects move faster, more energy is stored.

Examples of motion energy include wind, a flowing river, a moving car, or a person running. Sound energy is the movement of energy through substances.

It moves in waves and is produced when a force makes an object or substance vibrate. There is usually much less energy in sound than in other forms of energy. Elastic energy is a form of potential energy that is stored in an elastic object - such as a coiled spring or a stretched elastic band.

Elastic objects store elastic energy when a force causes them to be stretched or squashed. Gravitational energy is a form of potential energy.

It is an energy associated with gravity or gravitational force — in other words, the energy held by an object when it is in a high position compared to a lower position. While it might sound complex, the First Law of Conservation of energy simply states that energy can never be created or destroyed, but it can be transformed from one type to another.

Energy can be transformed from one form to another in different ways. The Law of Conservation of energy is that energy can be transformed from one form to another, but can be neither created or destroyed. Notice that these energy transfer examples only show the useful energy transfers. However, car engines are also noisy sound energy and hot thermal energy and electric lamps also give out heat energy.

Sunlight energy is converted into the chemical energy of glucose. Energy comes in many different types, which can be categorised into two basic forms — kinetic and potential. Energy can never be created or destroyed, but it can be transformed from one type of energy to another.

Knowledge Bank Energy Types of Energy. In a Flash Light is a form of radiant energy. Forms of energy There are many different types of energy, which all fall into two primary forms — kinetic and potential. What are the different types of energy? Radiant energy includes visible light, x-rays, gamma rays, and radio waves. Light is one type of radiant energy. Sunshine is radiant energy, which provides the fuel and warmth that make life on earth possible.

Thermal energy , or heat, is the energy that comes from the movement of atoms and molecules in a substance. Heat increases when these particles move faster. Geothermal energy is the thermal energy in the earth. Motion energy is energy stored in the movement of objects. The faster they move, the more energy is stored. It takes energy to get an object moving, and energy is released when an object slows down.

Wind is an example of motion energy. A dramatic example of motion energy is a car crash—a car comes to a total stop and releases all of its motion energy at once in an uncontrolled instant. Sound is produced when a force causes an object or substance to vibrate. The energy is transferred through the substance in a wave. Typically, the energy in sound is smaller than in other forms of energy.

Electrical energy is delivered by tiny charged particles called electrons, typically moving through a wire. Lightning is an example of electrical energy in nature. What is energy? Forms of energy. Units and calculators. Use of energy. Energy and the environment. Also in What is energy? Forms of energy Sources of energy Laws of energy. Example: Any form of light has electromagnetic energy , including parts of the spectrum we can't see.

Radio, gamma rays , x-rays, microwaves, and ultraviolet light are some examples of electromagnetic energy. Sonic energy is the energy of sound waves. Sound waves travel through the air or another medium. Example : A sonic boom, a song played on a stereo, your voice.

Energy associated with gravity involves the attraction between two objects based on their mass. It can serve as a basis for mechanical energy, such as the potential energy of an object placed on a shelf or the kinetic energy of the Moon in orbit around the Earth. Example : Gravitational energy holds the atmosphere to the Earth.

Kinetic energy is the energy of motion of a body. It ranges from 0 to a positive value. Example : An example is a child swinging on a swing. No matter whether the swing is moving forward or backward, the value of the kinetic energy is never negative.

Potential energy is the energy of an object's position. Example : When a child swinging on a swing reaches the top of the arc, she has maximum potential energy. When she is closest to the ground, her potential energy is at its minimum 0. Another example is throwing a ball into the air. At the highest point, the potential energy is greatest. As the ball rises or falls it has a combination of potential and kinetic energy. Ionization energy is the form of energy that binds electrons to the nucleus of its atom, ion, or molecule.

Example : The first ionization energy of an atom is the energy needed to remove one electron completely. The second ionization energy is energy to remove a second electron and is greater than that required to remove the first electron.
