What type of energy is stored in the spring of a watch?

During a process ideal gas expands to compress the spring such that 10kJ energy is stored in the spring and 2kJ heat is released from gas to surrounding find the change in internal energy of gas

The energy stored in wound watch spring is

In a winding (spring) watch, the energy is stored in the form of :

When a long spring is stretched by 1 cm, the potential energy stored in the spring is U. What will be the potential energy stored in it if it is stretched by 4 cm ?

Stored energy is

(a) What are the verious types of potential energy ? (b) What type of energy is stored in a dam ?

A vertical spring supports a beaker containing some water in it. Water slowly evaporates and the compression in the spring decreases. Where does the elastic potential energy stored in the spring go?

A block attached with an ideal spring is kept on a smooth horizontal surface. Now the free end of the spring is pulled with a constant velocity u horizontally. Then the maximum energy stored in the spring and bock system during subsequent motion is :

There are two identical springs, each of spring constant 240 N/m, one of them is compressed by 10cm and the other is stretched by 10 cm. What is the difference in the potential energies stored in the two springs ?
