Work, Energy and Power are fundamental concepts of Physics. Work is said to be done when a force (push or pull) applied to an object causes a displacement of the object. We define the capacity to do the work as energy. Power is the work done per unit of time.

- Work Energy Theorem And Its Application
Class 9 Chapter 11, ‘Work and Energy’, discusses the concept of work, energy and power in detail. In day-to-day life, we consider any useful physical or mental labour as work, but work is defined differently in science.
• Energy is defined as the capacity to do work. • Work done is the only way to transfer energy. • SI unit of energy is joule (J). v • The kinetic energy of a moving body is measured by the amount of work it can do before coming to rest • The total work done by the sum of all the forces acting on a particle

WORK, ENERGY AND POWER. 5.1 Introduction. 5.2 Notions of work and kinetic energy : The work-energy theorem. 5.3 Work. 5.4 Kinetic energy. 5.5 Work done by a variable force. 5.6 The work-energy theorem for. a variable force. 5.7 The concept of potential energy. 5.8 The conservation of mechanical energy.
We shall look at the vector product in Chapter 7. Here we take up the scalar product of two vectors. The scalar product or dot product of any two vectors A and B, denoted as A.B (read. WORK, ENERGY AND POWER. dot B) is defined as A.B = A B cos θ (6.1a) = A i + A j + A . y k. z. = B i + B j + B k .
