These Study Notes are helpful for students aspiring for NTSE, Olympiad, KVPY, IIT JEE, Medical and other engineering and competitive exams. The pre foundation courses offered by us are prepared by best faculties from all over India Energy. Energy is the capacity or ability of a body to do work. It is a scalar quantity. Its SI unit is the same as that of work i.e. joule (J). In CGS system, energy is measured in calorie (4.2 joule= 1 calorie) The change of one form of energy into another form of energy is called transformation of energy. For Ex:1)When a body is released from a height then potential energy is transferred into kinetic energy. 2)In a thermal power house. Chemical energy——>Heat energy—->Kinetic energy—->Electrical energy. 3)Electric motor

For example, a 2 kg mass moving with a speed of 3 m/s has a kinetic energy of 9 J. The above derivation shows that the net work is equal to the change in kinetic energy. This relationship is called the work‐energy theorem: W net = K. E. f − K. E. o, where K. E. f is the final kinetic energy and K. E. o is the original kinetic energy.

kinetic energy; in this situation, the object actually did work on you (equivalent to you doing negative work). Work W is the energy transferred to or from an object by means of a force acting on the object. Energy transferred to the object is positive work, and energy transferred from the object is negative work. Work - Definitio WORK. If an object or system, such as your body, exerts a force on an object and that force causes the object's position to change, you are doing work on the object. When a physicist is talking about work, he mainly talks about a force causing a displacement of an object in the same action of line. W=F.Δx

Chapter 11 - Work and Energy Exercise 152. Solution 1. Kinetic energy is the energy possessed by a body by the virtue of its motion. Every moving body possesses kinetic energy. In fact, kinetic energy of a body moving with a certain velocity is equal to the work done to make it acquire that velocity. Solution 2 1. Work done against these forces does not get conserved in the body in the form of P.E. 2. Work done against these forces is always dissipated by being converted into non usable forms of energy like heat, light, sound etc. 3. Work done against non-conservative force is a path function and not a state function. 4 10.1 Work and Energy: Energy is needed to make stationary objects move, change shape and warm them up.
