Work, Energy and Power..

Potential energy of an object can be defined as the energy possessed by the object by virtue of its position or conditio..

Stretched String Gains Potential Energy..

Study the following examples - a) Water stored in a reservoir is capable of rotating turbines, which are kept at a lower level i.e, water stored in a reservoir possesses energy. b) If you hit a nail hard with a hammer the nail gets fixed whereas if the hammer is just placed on the nail, t..

Consider an object of mass 'm', raised through a height 'h' above the earth's surface. The work done against gravity gets stored in the object as it's potential energy (gravitational potential energy). Therefore, potential energy = work do..

Potential Energy of a Single Charge - In the previous chapter, we learnt about specific charge, its location, and its electric field, but here we are considering the potential energy of a charge, in an external field. Consider an external electric field 'E' p..

Consider a massless spring of natural length 'l', one end of which is fastened to a wall. The other end is attached to a block, which is slowly pulled on a smooth horizontal surface, to extend the spring. If we take the spring as a system, when it is elongated by a distance 'x', the tension in it i..

Potential Energy of a System of Charges - Consider two charges q 1 and q 2 with position vectors r 1 and r 2 respectively, relative to some origin. To calculate externally the work done in building this configuration, we have to consider the charges q 1 and q 2 initially at infi..

2 due to q 1 . where 'r 1 2 ' is the distance between points 1 and 2. As the electrostatic force is conservative, the work done is stored as potential energy and is given by The potential 'V' would be same, even if the charge q 2 is brought from infinity to a p..
