>>Auditorium Auditorium A vibrant learning experience is about more than just classroom sessions. Guest lectures, symposia, seminars and conferences expose students to key insights, new ideas and a chance to engage with peers and experts in discussion and debate.

Our 1000-seater auditorium facilitates this free interplay of ideas. Air conditioned and equipped with modern equipment such as multimedia projectors and high quality sound systems, it has large lobbies and verandahs, which are ideal venues for conferences and exhibitions. Many dignitaries have graced this imposing edifice, the most prominent being the then President of India, His Excellency, Dr. For smaller seminars and meetings, there is a mini auditorium which can hold 300 people. With a growing number of seminars and symposia being held across disciplines, each department also has its own fully-equipped, capacious seminar hall.

• • • Mass is both a of a and a of its to (a change in its state of ) when a is applied. It also determines the of its mutual attraction to other bodies. The basic of mass is the (kg). In, mass is not the same as, even though mass is often determined by measuring the object's weight using a, rather than comparing it directly with known masses. An object on the Moon would weigh less than it does on Earth because of the lower gravity, but it would still have the same mass. This is because weight is a force, while mass is the property that (along with gravity) determines the strength of this force.

In, mass can be generalized as the amount of in an object. However, at very high speeds, states that the of its motion becomes a significant additional source of mass. Thus, any stationary body having mass has an amount of energy, and all resist acceleration by a force and have gravitational attraction. In, matter is not a fundamental concept because its definition has proven elusive.

There are several distinct phenomena which can be used to measure mass. Although some theorists have speculated that some of these phenomena could be independent of each other, current experiments have found no difference in results regardless of how it is measured: • Inertial mass measures an object's resistance to being accelerated by a force (represented by the relationship F = ma). Curious Turtle Rapidshare.

• Active gravitational mass measures the gravitational force exerted by an object. • Passive gravitational mass measures the gravitational force exerted on an object in a known gravitational field. The mass of an object determines its acceleration in the presence of an applied force. The inertia and the inertial mass describe the same properties of physical bodies at the qualitative and quantitative level respectively, by other words, the mass quantitatively describes the inertia. According to, if a body of fixed mass m is subjected to a single force F, its acceleration a is given by F/ m. A body's mass also determines the degree to which it generates or is affected by a.

If a first body of mass m A is placed at a distance r (center of mass to center of mass) from a second body of mass m B, each body is subject to an attractive force F g = Gm A m B/ r 2, where G = 000000000♠6.67 ×10 −11 N kg −2 m 2 is the 'universal '. This is sometimes referred to as gravitational mass. Repeated experiments since the 17th century have demonstrated that inertial and gravitational mass are identical; since 1915, this observation has been entailed in the of. Audit Checklist Iso 27001 Standard. The kilogram is one of the seven and one of three which is defined ad hoc (i.e.

Without reference to another base unit). The standard (SI) unit of mass is the (kg). The kilogram is 1000 grams (g), first defined in 1795 as one cubic decimeter of water at the of ice. Then in 1889, the kilogram was redefined as the mass of the, and as such is independent of the meter, or the properties of water. However, the mass of the international prototype and its identical national copies have been found to be drifting over time.

It is expected that the on May 20, 2019, following a final vote by the in November 2018. The new definition will use only invariant quantities of nature: the, the, and the. Other units are accepted for use in SI: • the (t) (or 'metric ton') is equal to 1000 kg. • the (eV) is a unit of, but because of the it can easily be converted to a unit of mass, and is often used like one. In this context, the mass has units of eV/ c 2 (where c is the speed of light). The electronvolt and its multiples, such as the MeV (megaelectronvolt), are commonly used in. • the (u) is 1/12 of the mass of a atom, approximately 000000000♠1.66 ×10 −27 kg.

The atomic mass unit is convenient for expressing the masses of atoms and molecules. Outside the SI system, other units of mass include: • the (sl) is an of mass (about 14.6 kg). • the (lb) is a unit of both mass and force, used mainly in the United States (about 0.45 kg or 4.5 N). In scientific contexts where and need to be distinguished, SI units are usually used instead. • the ( m P) is the maximum mass of point particles (about 000000000♠2.18 ×10 −8 kg).

It is used in. • the ( M ☉) is defined as the mass of the. It is primarily used in astronomy to compare large masses such as stars or galaxies (≈ 000000000♠1.99 ×10 30 kg). • the mass of a very small particle may be identified by its inverse ( 1 cm −1 ≈ 000000000♠3.52 ×10 −41 kg).

• the mass of a very large star or may be identified with its ( 1 cm ≈ 000000000♠6.73 ×10 24 kg). Definitions of mass [ ]. See also: In 1600 AD, sought employment with, who had some of the most precise astronomical data available.

Using Brahe's precise observations of the planet Mars, Kepler spent the next five years developing his own method for characterizing planetary motion. In 1609, Johannes Kepler published his three laws of planetary motion, explaining how the planets orbit the Sun. In Kepler's final planetary model, he described planetary orbits as following paths with the Sun at a focal point of the ellipse. Kepler discovered that the of the of each planet is directly to the of the of its orbit, or equivalently, that the of these two values is constant for all planets in the.

On 25 August 1609, demonstrated his first telescope to a group of Venetian merchants, and in early January 1610, Galileo observed four dim objects near Jupiter, which he mistook for stars. However, after a few days of observation, Galileo realized that these 'stars' were in fact orbiting Jupiter. These four objects (later named the in honor of their discoverer) were the first celestial bodies observed to orbit something other than the Earth or Sun.

Galileo continued to observe these moons over the next eighteen months, and by the middle of 1611 he had obtained remarkably accurate estimates for their periods. Galilean free fall [ ]. Main article: Newton's cannonball was a used to bridge the gap between Galileo's gravitational acceleration and Kepler's elliptical orbits. It appeared in Newton's 1728 book A Treatise of the System of the World. According to Galileo's concept of gravitation, a dropped stone falls with constant acceleration down towards the Earth. However, Newton explains that when a stone is thrown horizontally (meaning sideways or perpendicular to Earth's gravity) it follows a curved path. 'For a stone projected is by the pressure of its own weight forced out of the rectilinear path, which by the projection alone it should have pursued, and made to describe a curve line in the air; and through that crooked way is at last brought down to the ground.

And the greater the velocity is with which it is projected, the farther it goes before it falls to the Earth.' : 513 Newton further reasons that if an object were 'projected in an horizontal direction from the top of a high mountain' with sufficient velocity, 'it would reach at last quite beyond the circumference of the Earth, and return to the mountain from which it was projected.' [ ] Universal gravitational mass [ ]. An apple experiences gravitational fields directed towards every part of the Earth; however, the sum total of these many fields produces a single gravitational field directed towards the Earth's center In contrast to earlier theories (e.g. ) which stated that the heavens were made of entirely different material, Newton's theory of mass was groundbreaking partly because it introduced: every object has gravitational mass, and therefore, every object generates a gravitational field. Newton further assumed that the strength of each object's gravitational field would decrease according to the square of the distance to that object.

If a large collection of small objects were formed into a giant spherical body such as the Earth or Sun, Newton calculated the collection would create a gravitational field proportional to the total mass of the body,: 397 and inversely proportional to the square of the distance to the body's center.: 221 For example, according to Newton's theory of universal gravitation, each carob seed produces a gravitational field. Therefore, if one were to gather an immense number of carob seeds and form them into an enormous sphere, then the gravitational field of the sphere would be proportional to the number of carob seeds in the sphere. Hence, it should be theoretically possible to determine the exact number of carob seeds that would be required to produce a gravitational field similar to that of the Earth or Sun.

In fact, by it is a simple matter of abstraction to realize that any traditional mass unit can theoretically be used to measure gravitational mass. Main article: Typically, the mass of objects is measured in relation to that of the kilogram, which is defined as the mass of the (IPK), a platinum alloy cylinder stored in an environmentally-monitored safe secured in a vault at the in France. However, the IPK is not convenient for measuring the masses of atoms and particles of similar scale, as it contains trillions of trillions of atoms, and has most certainly lost or gained a little mass over time despite the best efforts to prevent this.

It is much easier to precisely compare an atom's mass to that of another atom, thus scientists developed the (or Dalton). By definition, 1 u is exactly one twelfth of the mass of a atom, and by extension a carbon-12 atom has a mass of exactly 12 u. This definition, however, might be changed by the, which will leave the Dalton very close to one, but no longer exactly equal to it. Mass in relativity [ ] Special relativity [ ].
