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.
Work energy and power formulas pdf.
Work can be used to understand the energy of many objects that experience forces.
Revision notes on work power and energy.
Power is defined as work done per unit time.
H m is the mass g is the gravitational acceleration and h is the distance potential energy of the spring.
Here θ is the angle between and.
This signifies when the force and displacement are in same.
X k is the spring constant and x is the amount of compression or streching kinetic energy.
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.
Work energy and power tuesday february 10th reading.
Ek 1 2mv m is the mass v is the velocity work power energy exams and solutions.
Up to page 88 in the text book ch.
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 the force is positive if the angle between force and displacement is acute 0 θ 90 as cos θ is positive.
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.
In this article we will learn all about the concept of work power and energy.
Work work done w is defined as the dot product of force f and displacement s.
Work done is generally referred in relation to the force applied while energy is used in reference to other factors such as heat.
