The work-energy theorem states that the change in kinetic energy of a body is the workdone by the net force on the body. For a conservative force in one dimension, we may define a potential energy function V x such that. The principle of conservation of mechanical energy states that the total mechanicalenergy of a body remains constant if the only forces that act on the body are conservative.

Learning the important concepts is very important for every student to get better marks in examinations. The concepts should be clear which will help in faster learning. Important updates relating to your studies which will help you to keep yourself updated with latest happenings in school level education. Keep yourself updated with all latest news and also read articles from teachers which will help you to improve your studies, increase motivation level and promote faster learning.

Celebration of this occasion annually helps youth and children of our country to be aware of the significance of Indian Constitution, unity It is an Academic Institution assisting educational based competition and enhancing competitive spirit among the School- Level students.

It is measured by the product of the force and the distance moved in the direction of the force, i. The work done W by the agent is the product of the component of force in the direction of displacement and the magnitude of displacement. The negative sign indicates that the direction of the spring force is opposite to x, the displacement of the free-end. Anything which is able to do work is said to possess energy. Energy is measured in the same unit as that of work, namely, Joule. Mechanical energy is of two types: Kinetic energy and Potential energy.

Work done by the force is equal to the product of the force and the displacement of the object in the direction of force. Work done by a force is zero, if a body is not displaced actually, i. Work done by a force is negative if angle between F and s is obtuse angle. Work done by a constant force depends only on the initial and final Positions and not on the actual path followed between initial and final positions. Gravitational force, electrostatic force, magnetic force, etc are conservative forces.

Here in Vedantu, we believe in the quality of education. Many students rely on the Vedantu program. We do not break their trust.

Мотоцикл Беккера показался рядом с ним детской игрушкой, выехавшей на автостраду. Метрах в пятистах сзади в снопе искр на шоссе выкатило такси. Набирая скорость, оно столкнуло в сторону Пежо-504, отбросив его на газон разделительной полосы.

Время, казалось, замедлило свой бег. - Мы терпим бедствие! - крикнул техник.  - Все линии устремились к центру. С левого экрана в камеру неотрывно смотрели Дэвид и агенты Смит и Колиандер.

Я позвоню и все объясню. Мне в самом деле пора идти, они связи, обещаю. - Дэвид! - крикнула .

Пуля отскочила от голой стены и чуть не попала в него. Он стремительно развернулся и едва сдержал крик. Никого. Дэвид Беккер исчез.

ГЛАВА 116 - Читайте, мистер Беккер! - скомандовал Фонтейн. Джабба сидел весь потный, положив руки на клавиатуру. - Да, да, - сказал он, - читайте эту благословенную надпись.

Что-что. - Как это тебе нравится. Он аккуратно размазал приправу кончиком салфетки.

Я вам все верну. Беккер подумал, что деньги, которые он ей даст, в конечном счете окажутся в кармане какого-нибудь наркоторговца из Трианы. - Я вовсе не так богат, я простой преподаватель.

Джабба окончательно убедился: директор рискнул и проиграл. Шеф службы обеспечения систем безопасности спустился с подиума подобно грозовой туче, сползающей с горы, и окинул взглядом свою бригаду программистов, отдающих какие-то распоряжения. - Начинаем отключение резервного питания.
