write a short note on energy
Answers
Answer:
energy is the quantitative property that must be transferred to a body or physical system to perform work on the body, or to heat it. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement in the International System of Units (SI) of energy is the joule, which is the energy transferred to an object by the work of moving it a distance of
The Sun is the source of energy for most of life on Earth. It derives its energy mainly from nuclear fusion in its core, converting nuclear binding energy to other forms such as radiant energy as protons are combined to form helium. This energy is transported to the sun's surface then released into space mainly in the form of radiant (light) energy.
Energy is the fundamental form of living for all living beings. There are different forms of energy on this planet. The Sun is considered as the elemental form of energy on the Earth. In Physics, energy is considered a quantitative property which can be transferred from an object in order for it to perform work. Hence, we can define energy as the strength to do any kind of physical activity. Thus, they say,
Energy is the ability to do work
According to the laws of conservation of energy it states that “the energy can neither be created nor destroyed but can only be converted from one form to another”. The SI unit of energy is Joule. In this article, let us understand in detail about units of energy and different forms of energy.
