Class 11 Physics Revision Notes for Chapter 6 - Work, Energy and Power

Consider a particle of mass m moving linearly with an applied force F constantly acting on it. Consider a particle, mass m, speed v, being moved along the x-axis by a force of magnitude F. The applied force F is proportional to the displacement of the particle x, along the x-axis. This is the energy a mass posesses by virtue of its position. It is equal to the product of mass, gravitational field strength g and the vertical distance the particle is above a fixed level.

The principle of work and kinetic energy also known as the work-energy theorem states that the work done by the sum of all forces acting on a particle equals the change in the kinetic energy of the particle. This definition can be extended to rigid bodies by defining the work of the torque and rotational kinetic energy. Kinetic Energy : A force does work on the block. The kinetic energy of the block increases as a result by the amount of work. This relationship is generalized in the work-energy theorem.

Here in Vedantu, we believe in the quality of education. Many students rely on the Vedantu program. We do not break their trust. Many students got successful in past years and we plan to do something different to make it more comfortable for the aspirants. Students presently studying in Class 11 are welcome to join us. This program is completely based upon the CBSE board syllabus. This program is helpful for those who want to get the best marks.

Mechanics: Work, Energy and Power

Suppose a force F acts on a body, causing it to move in a particular direction. Work done is measured in joules which has symbol J. Now suppose that this force is at an angle of a to the horizontal. Now suppose that the force we are considering is one which causes a body to be lifted off of the ground. We call the work done by the force the "work done against gravity".

Может. - Сьюзан пожала плечами, демонстрируя равнодушие. - Мы с ним какое-то время переписывались, - как бы невзначай сказал Хейл. - С Танкадо.

This set of 32 problems targets your ability to use equations related to work and power, to calculate the kinetic, potential and total mechanical energy, and to use the work-energy relationship in order to determine the final speed, stopping distance or final height of an object.
