Question

give scientific reason the clock gets potential energy when its spring is wound​

Answer 1

Answer:

When the spring of the clock is wound the work done on the spring by winding it gets stored in it as a potential energy (PE). This Potential Energy can be utilised by the clock mechanism to operate.

If the spring constant is k then by winding it for length x, the potential energy stored in the spring will be $\frac{1}{2}kx^2$

Hope this answer is helpful.

Answer 2

Answer:

The spring gets the potential energy after winding against the movement of the clock because the work done by the action of winding on the spring is stored as the Potential Energy of the Spring. The Potential energy, hence stored is further used for the mechanism of the clock to work.

The potential energy stored in the spring can be given by,

P = -k.x

where,

'k' is the Spring Constant and 'x' is the displacement of the spring that takes place because it gets winded about the clock's axle.
