work done when the force on the object is zero? What would be the work done when the displacement of the object is zero? Refer to the conditions that are to be satisfied to say that work is done. Example 11.1 A force of 5 N is acting on an object. The object is displaced through 2 m in the direction of the force (Fig. 11.2). If the force acts ...

23 sty 2024 · Work: When a force acts on an object and the object shows displacement, the force has done work on the object. Two conditions need to be satisfied for work to be done: (i) A force should act on object
In this section, students learn how work determines changes in kinetic energy and that power is the rate at which work is done. [BL] [OL] Review understanding of mass, velocity, and acceleration due to gravity.
Work done by the force of gravity on an object depends only on vertical displacement. Vertical displacement is given by the difference in the initial and final positions/heights of the object, which is zero.
