An object having a capability to do work is said to possess energy. The object which does the work loses energy and the object on which the work is done gains energy. How does an object with energy do work? An object that possesses energy can exert a force on another object. When this happens, energy is transferred from the former to the latter.

5 gru 2018 · WORK, ENERGY AND POWER 1. INTRODUCTION This chapter explains the concepts of work and energy and how these quantities are related to each other. The law of conservation of energy is an important tool in physics, for the analysis of motion of a system of particles or bodies, and in understanding various phenomena in nature.
24 maj 2024 · Work-Energy Theorem. The work-energy theorem states that the net work done by a moving body can be calculated by finding the change in KE. Factors Affecting Kinetic Energy. Mass; Velocity; Momentum; Potential Energy. When work is done on an object, energy can be stored in it. As an illustration, extend a rubber thread.
19 maj 2022 · Work is said to be done if (l) a force is applied on the object and (ii) the object is displaced from its original position. Work done by a force acting on an object is equal to the product of the force (F) and the displacement (s) of the object in the direction of the force, i.e., W = F × s = Fs.
