Answer:
1. Energy is a quantitive property that can be transferred to a another object in order to perform work on, or to heat the object.
Energy has a different forms, such as light energy, heat energy, mechanical energy, gravitational energy, electrical energy, sound energy, chemical energy, nuclear or atomic energy and so on. Potential energy is any form of energy that has stored potential that can be put to future use.
2. There are different forms of energy, first is the Chemical Energy where in the stored bonds of atoms and molecules is the energy that holds these particles together.
Nuclear Energy is stored in the nucleus of atoms. This energy is released when the nuclei are combined (fusion) or split apart (fission).
Electrical Energy movement of electrons (the tiny particles that makeup atoms, along with protons and neutrons). Electrons that move through a wire are called electricity. Lightning is another example of electrical energy.
Radiant Energy 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 movement of energy through substances. It moves in waves and is produced when a force makes an object or substance vibrate.
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. And lastly the
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.
3. There are many forms of energy: like solar, wind, wave and thermal to name a few, but the 6 Forms of Energy we study in Needham are: Sound, Chemical, Radiant, Electric, Atomic and Mechanical. Sound Energy- is produced when an object is made to vibrate.
