We explain the work-energy theorem and solve an example problem involving the equations for work and kinetic energy. We also discuss when work has a positive or negative value.

Obtain, evaluate, and communicate information about the importance of conservation laws for mechanical energy and linear momentum in predicting the behavior of physical systems. Use mathematics and computational thinking to analyze, evaluate, and apply the principle of conservation of energy and the Work-Kinetic Energy Theorem.

Energy , in physics , the capacity for doing work. It may exist in potential , kinetic , thermal , electrical, chemical , nuclear , or other various forms. There are, moreover, heat and work—i. After it has been transferred, energy is always designated according to its nature. Hence, heat transferred may become thermal energy , while work done may manifest itself in the form of mechanical energy.

Question 6. The sign of work done by a force on a body is important to understand. State carefully if the following quantities are positive or negative: a Work done by a man in lifting a bucket out of a well by means of a rope tied to the bucket, b Work done by gravitational force in the above case, c Work done by friction on a body sliding down an inclined plane, d Work done by an applied force on a body moving on a rough horizontal plane with uniform velocity, e Work done by the resistive force of air on a vibrating pendulum in bringing it to rest. Compute the a Work done by the applied force in 10 s b Work done by friction in 10 s c Work done by the net force on the body in 10 s d Change in kinetic energy of the body in 10 s and interpret your results. Given figures are examples of some potential energy functions in one dimension. The total energy of the particle is indicated by a cross on the ordinate axis.

In physics , energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat , the object. The SI unit of energy is the joule , which is the energy transferred to an object by the work of moving it a distance of 1 metre against a force of 1 newton. Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object's position in a force field gravitational , electric or magnetic , the elastic energy stored by stretching solid objects, the chemical energy released when a fuel burns , the radiant energy carried by light, and the thermal energy due to an object's temperature. Mass and energy are closely related. Due to mass—energy equivalence , any object that has mass when stationary called rest mass also has an equivalent amount of energy whose form is called rest energy , and any additional energy of any form acquired by the object above that rest energy will increase the object's total mass just as it increases its total energy. For example, after heating an object, its increase in energy could be measured as a small increase in mass, with a sensitive enough scale. ## Service Unavailable in EU region

### Segment F: Work-Energy Theorem

Renatta Gass is out with her friends. Misfortune occurs and Renatta and her friends find themselves getting a work out. They apply a cumulative force of N to push the car m to the nearest fuel station. Determine the work done on the car. Hans Full is pulling on a rope to drag his backpack to school across the ice.

Читайте медленно и точно! - приказал Джабба.  - Одна неточность, и все мы погибли. Фонтейн сурово взглянул на. Уж о чем о чем, а о стрессовых ситуациях директор знал. Он был уверен, что чрезмерный нажим не приведет ни к чему хорошему. - Расслабьтесь, мистер Беккер.

Он хотел, чтобы оно оказалось как можно дальше от него - чтобы мы его никогда не нашли. - Но, директор, - возразила Сьюзан, - это не имеет смысла. Если Танкадо не понял, что стал жертвой убийства, зачем ему было отдавать ключ. - Согласен, - сказал Джабба.  - Этот парень был диссидентом, но диссидентом, сохранившим совесть. Одно дело - заставить нас рассказать про ТРАНСТЕКСТ, и совершенно другое - раскрыть все государственные секреты. Фонтейн не мог в это поверить. Верхняя пуговица блузки расстегнулась, и в синеватом свете экрана было видно, как тяжело вздымается ее грудь. Она в ужасе смотрела, как он придавливает ее к полу, стараясь разобрать выражение его глаз. Похоже, в них угадывался страх. Или это ненависть. Они буквально пожирали ее тело. - Дамы и господа, - он опять тяжело вздохнул, - перед вами компьютерный агрессор-камикадзе… червь. - Червь? - с недоумением переспросил Бринкерхофф. Название показалось ему чересчур земным для такого агрессора. - Червь, - недовольно сказал Джабба.  - Никакой усложненной структуры, один лишь инстинкт: жри, опорожняйся и ползи.

In physics, however, the word 'Work' covers a definite and precise meaning. Somebody who has the capacity to work for hours a day is said to have a large.

Closely related to work are energy and power. In this chapter we shall study these concepts. All living beings need food. Living beings have to perform several.
