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.

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.

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.

The work done by the force is defined to be the product of component of the force in the direction of the displacement and the magnitude of this displacement. The variable force is more commonly encountered than the constant force.

Второй раз за один вечер. Что подумают люди. - В шифровалке проблемы.  - Она безуспешно старалась говорить спокойно. Джабба нахмурился.

Беккер еще больше усилил акцент, но так, чтобы собеседница могла понять, что ему нужно, и говорил слегка сбивчиво, подчеркивая свою крайнюю озабоченность. Люди часто нарушают правила, когда сталкиваются с подобной настойчивостью. Но вместо того чтобы нарушить правила, женщина выругала самоуверенного североамериканца и отсоединилась. Расстроенный, Беккер повесил трубку.
