Any force which conserves mechanical energy, as opposed to a nonconservative force. See statement of conservation of mechanical energy. Property of conservative forces which states that the work done on any path between two given points is the same. The energy of configuration of a conservative system. For formulae, see Definition of potential energy, gravitational potential energy, and Definition of potential energy given a position-dependent force. The sum of the kinetic and potential energy of a conservative system. See definition of total mechanical energy.

In physics , work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form, it is often represented as the product of force and displacement. A force is said to do positive work if when applied it has a component in the direction of the displacement of the point of application. A force does negative work if it has a component opposite to the direction of the displacement at the point of application of the force. For example, when a ball is held above the ground and then dropped, the work done by the gravitational force on the ball as it falls is equal to the weight of the ball a force multiplied by the distance to the ground a displacement. Work is a scalar quantity , [1] so it has only magnitude and no direction. Work transfers energy from one place to another, or one form to another.

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.

Мысли ее мешались: она тосковала по Дэвиду и страстно желала, чтобы Грег Хейл отправился домой. Но Хейл сидел на месте и помалкивал, поглощенный своим занятием. Ей было безразлично, чем именно он занят, лишь бы не заинтересовался включенным ТРАНСТЕКСТОМ.

Если же нет, то позвони электрикам. - Джабба, дело очень серьезное. У меня чутье. У нее чутье. Ну вот, на Мидж снова что-то нашло.

Звук показался очень далеким, едва различимым в шуме генераторов. Она никогда раньше не слышала выстрелов, разве что по телевизору, но не сомневалась в том, что это был за звук. Сьюзан словно пронзило током. В панике она сразу же представила себе самое худшее. Ей вспомнились мечты коммандера: черный ход в Цифровую крепость и величайший переворот в разведке, который он должен был вызвать.

Как это удобно. Вспомнив всю услышанную от шефа ложь, она похолодела и посмотрела на него, в глазах ее мелькнуло подозрение. - Это вы убили Танкадо.

Беккеру удалось оторваться от убийцы, и он рванулся к двери. Халохот шарил по полу, нащупывая пистолет. Наконец он нашел его и снова выстрелил.

Беккер вытер лицо рукавом пиджака, и тут его осенило. От волнений и переживаний он совсем забыл, где находится. Он же в аэропорту.
