Chapter Notes: Work, Energy and Power Physics Class 11
Notes for Work, Energy and Power chapter of class 11 physics. If there is no change in the position of the body, work is not done. Our special definition of the word work does not correspond to the colloquial usage of the term. Thus, we may exert a large force on a wall, but if the wall remains where it is, then we have not done any work. We may be doing hard work in physiological sense, but from the point of view of physics, we are not doing any work. If a coolie holding a heavy box on his head is standing at a fixed location, he is not doing any work. Work is said to be done only when there is a displacement in the direction of force.

These notes are made out of the past 10 years question papers and study material which help the students cover each and every concept given in the chapter. Work, Energy and Power Class 11 Notes would provide you with clear understanding and retention of the course content which would help you score more marks. 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. The kinetic energy of an object is a measure of the work an object can do by the virtue of its motion.
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.

There are stories of innovation, sacrifice, going beyond the call of duty, challenges faced and creatively solved, humour, finding joy in adversity etc. It will be highly useful to
Power = Rate of doing work = Work done / Time taken. If under a constant force F a body is displaced through a distance s in time t, the power p = W / t = F * s / t.

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.

Быть может, смерть Танкадо в публичном месте была необходимостью, однако публика возникла чересчур. Халохот был вынужден скрыться, не успев обыскать убитого, найти ключ. А когда пыль осела, тело Танкадо попало в руки местной полиции. Стратмор был взбешен.
- Я не из севильской полиции. Меня прислала сюда американская правительственная организация, с тем чтобы я нашел кольцо. Это все, что я могу вам сказать. Я уполномочен заплатить вам за. На мгновение в комнате повисла тишина, затем Росио приоткрыла губы в хитрой улыбке.
Фонтейн повернулся к Сьюзан. - Как вы думаете, мисс Флетчер. Сьюзан задумалась. Она чувствовала, что здесь что-то не то, но не могла сообразить, что. Она достаточно хорошо знала Танкадо и знала, что он боготворил простоту.
Беккер закрыл глаза и попытался сосредоточиться. Итак, каков следующий шаг. Он решил подумать об этом через минуту.
