In physics Physics is a natural science; it is the study of matter and its motion through spacetime and all that derives from these, such as energy and force. More broadly, it is the general analysis of nature, conducted in order to understand how the world and universe behave, mass–energy equivalence is the concept that the mass In physics, mass commonly refers to any of three properties of matter, which have been shown experimentally to be equivalent: inertial mass, active gravitational mass and passive gravitational mass. In everyday usage, mass is often taken to mean weight of a body is a measure of its energy In physics, energy is a scalar physical quantity that describes the amount of work that can be performed by a force, an attribute of objects and systems that is subject to a conservation law. Different forms of energy include kinetic, potential, thermal, gravitational, sound, light, elastic, and electromagnetic energy. The forms of energy are content. The mass of a body as measured on a scale is always equal to the total energy inside, multiplied by a constant c2 that changes the units appropriately:
where E is energy, m is mass In physics, mass commonly refers to any of three properties of matter, which have been shown experimentally to be equivalent: inertial mass, active gravitational mass and passive gravitational mass. In everyday usage, mass is often taken to mean weight, and c is the speed of light In physics, the speed of light is a physical constant, the speed at which electromagnetic radiation, such as light, travels in free space (i.e., perfect vacuum). Its value is 299,792,458 metres per second (see the table on the right for conversions). In the theory of special relativity, c is an important constant connecting space and time in the in a vacuum, which is 299,792,458 meters per second Metre per second is an SI derived unit of both speed (scalar) and velocity (vector quantity which specifies both magnitude and a specific direction), defined by distance in metres divided by time in seconds.
Mass–energy equivalence was proposed in Albert Einstein Albert Einstein (pronounced /ˈælbərt ˈaɪnstaɪn/; German: [ˈalbɐt ˈaɪ̯nʃtaɪ̯n] ; 14 March 1879 – 18 April 1955) was a theoretical physicist. His many contributions to physics include the special and general theories of relativity, the founding of relativistic cosmology, the first post-Newtonian expansion, explaining the perihelion's 1905 paper, "Does the inertia of a body depend upon its energy-content?", one of his Annus Mirabilis The Annus Mirabilis papers are the papers of Albert Einstein published in the Annalen der Physik scientific journal in 1905. These four articles contributed substantially to the foundation of modern physics and changed views on space, time, and matter. The Annus Mirabilis is often called the "Miracle Year" in English or in German, the & ("Miraculous Year") Papers.[1] Einstein was not the first to propose a mass–energy relationship, and various similar formulas appeared before Einstein's theory with incorrect numerical coefficients and an incomplete interpretation. Einstein was the first to propose the simple formula and the first to interpret it correctly: as a general principle which follows from the relativistic symmetries Spacetime symmetries refers to aspects of spacetime that can be described as exhibiting some form of symmetry. The role of symmetry in physics is important, for example, in simplifying solutions to many problems. Spacetime symmetries are used to simplify problems and find ample application in the study of exact solutions of Einstein's field of space and time In physics, spacetime is any mathematical model that combines space and time into a single continuum. Spacetime is usually interpreted with space being three-dimensional and time playing the role of a fourth dimension that is of a different sort than the spatial dimensions. According to certain Euclidean space perceptions, the universe has three.
In the formula, c2 is the conversion factor In Mathematics, specifically Algebra, a Conversion Factor is used to convert a measured quantity to a different unit of measure without changing the amount. To accomplish this, a ratio is established that equals one (1) required to convert from units of mass to units of energy. The formula does not depend on a specific system of units A system of measurement is a set of units which can be used to specify anything which can be measured and were historically important, regulated and defined because of trade and internal commerce. Scientifically, when later analyzed, some quantities are designated as fundamental units meaning all other needed units can be derived from them,. Using the International System of Units The International System of Units is the modern form of the metric system and is generally a system devised around the convenience of the number ten. It is the world's most widely used system of measurement, both in everyday commerce and in science, joules The joule , named for James Prescott Joule, is the derived unit of energy in the International System of Units. It is the energy exerted by a force of one newton acting to move an object through a distance of one metre. In terms of dimensions: are used to measure energy, kilograms The kilogram is the base unit of mass in the International System of Units (SI, from the French Le Système International d’Unités).[Note 2] The kilogram is defined as being equal to the mass of the International Prototype Kilogram (IPK),[Note 3] which is almost exactly equal to the mass of one liter of water. It is the only SI base unit with for mass, meters per second Metre per second is an SI derived unit of both speed (scalar) and velocity (vector quantity which specifies both magnitude and a specific direction), defined by distance in metres divided by time in seconds for speed. Note that 1 joule equals 1 kg The kilogram is the base unit of mass in the International System of Units (SI, from the French Le Système International d’Unités).[Note 2] The kilogram is defined as being equal to the mass of the International Prototype Kilogram (IPK),[Note 3] which is almost exactly equal to the mass of one liter of water. It is the only SI base unit with·m The metre or meter is the basic unit of length in the International System of Units . Historically, the metre was defined by the French Academy of Sciences as the length between two marks on a platinum-iridium bar, which was designed to represent one ten-millionth of the distance from the Equator to the North Pole through Paris. In 1983, the metre2/s The second , sometimes abbreviated sec., is the name of a unit of time, and is the International System of Units (SI) base unit of time. It may be measured using a clock2. In unit-specific terms, E (in joules The joule , named for James Prescott Joule, is the derived unit of energy in the International System of Units. It is the energy exerted by a force of one newton acting to move an object through a distance of one metre. In terms of dimensions:) = m (in kilograms The kilogram is the base unit of mass in the International System of Units (SI, from the French Le Système International d’Unités).[Note 2] The kilogram is defined as being equal to the mass of the International Prototype Kilogram (IPK),[Note 3] which is almost exactly equal to the mass of one liter of water.

In natural units In physics, natural units are physical units of measurement defined in such a way that certain selected universal physical constants are normalized to unity; that is, their numerical value becomes exactly 1, the speed of light is set equal to 1, and the formula becomes an identity.
