A string of length `L` and force constant `k` is stretched to obtain extension `l`. It is further stretched to obtain extension `l_1`,. The work done in second stretching
A massless spring of spring constant `k`, has extension `y` and potential energy `E`. It is now stretched from `y` to `2y`. The increase in its potential energy
There are many types of spring. Important among these are helical and spiral springs as shown in figure.(a) (b) Usually, we assume that the springs are massless. Therefore, work done is stored in the spring in the form of elastic potential energy of the spring. Thus, potential energy of a spring is the energy associated with the state of compression or expansion of an elastic spring.The potential energy of a spring increases by `15 J` when stretched by 3 cm. If it is stretched by 4 cm, the increase in potential energy
Work A farmer ploughing the field, a construction worker carrying bricks, a student studying for a competitive examination, an artist painting a beautiful landscape, all are said to be working. In physics, however, the word ‘Work’ covers a definite and precise meaning. Work refers to the force and the displacement over which it acts. Consider a constant force `F` acting on an object of mass `m`. The object undergoes a displacement `d` in the positive `x`-direction as shown in figure.The work done by the force is defined to be the product of component of the force in the direction of
