Work Energy And Power Formulas Pdf

X k is the spring constant and x is the amount of compression or streching kinetic energy.

Work energy and power formulas pdf.

H m is the mass g is the gravitational acceleration and h is the distance potential energy of the spring. Work can be used to understand the energy of many objects that experience forces. Work work done w is defined as the dot product of force f and displacement s. This signifies when the force and displacement are in same.

Free pdf download of physics class 11 chapter 6 work energy and power formula prepared by subject expert teacher at vedantu. 6 finish newton s laws and circular motion energy work definition examples of work work and kinetic energy conservative and non conservative forces work and potential energy conservation of energy. One example is the work required to stretch a spring. Work done by the force is equal to the product of the force and the displacement of the object in the direction of force.

Revision notes on work power and energy. Up to page 88 in the text book ch. Work formula example of work types of energy power formula questions. In this article we will learn all about the concept of work power and energy.

Work done by the force is positive if the angle between force and displacement is acute 0 θ 90 as cos θ is positive. Work done is generally referred in relation to the force applied while energy is used in reference to other factors such as heat. If the magnitude of the displacement of the object is labeled x and this represents the displacement away from an equilibrium position x 0 then the force required to pull the object on the spring to a. Physics notes class 11 chapter 6 work energy and power work when a force acts on an object and the object actually moves in the direction of force then the work is said to be done by the force.

Power is defined as work done per unit time. Before moving to physics formula pdf sheet of chapter work energy power complete the theory form your text book than read the physics formula sheet of entrancei for effective revision do practice the questions from entrancei physics sections of chapter work energy power.
