The elastic potential enegry of a stretched spring is given by `E = 50 x^(2)`. Where `x` is the displacement in meter and and `E` is in joule, then the force constant of the spring is

Derive an expression for potential energy of a stretched elastic spring.

(A): The elastic potential energy of spring increases when it is elongated and decreases when it is compressed. (R) : Work done on a spring is independent of the force constant of the spring.

(a) What is elastic potential energy of a spring ? Obtain the relation for elastic P.E. U=(1)/(2)kx^(2) . Where k is force constant of spring, x is extension or compression produced in the spring.

The potential energy of a spring pendulum, with a mass m connected to it, is given by V=1/2kx^(2) (where x = displacement from the position of equilibrium and k = a constant). How does the applied force on the mass vary with displacement?

Draw force-displacement graph and find an expression for the potential energy of an elastic spring ?

The potential energy of a long spring when stretched by 2 cm is U. If the spring is stretched by 8 cm the potential energy stored in it is :
