Unlike a weight on a cord, which exerts a constant force to turn the clock's wheels, the force a spring exerts diminishes as the spring unwinds.

Then when the light is turned on, the spring unwinds, turning a generator to provide power to run the light.

The force provided by a spring is not constant, but decreases as the spring unwinds.

A problem throughout the history of spring driven clocks and watches is that the force (torque) provided by a spring is not constant, but diminishes as the spring unwinds (see graph).

But it was not a conquering sort of army, because the springs in the soldiers' backs unwound rapidly, and they did not have the adaptability of human soldiers.

When the door is raised, the springs unwind and the stored tension lifts the door by turning the shaft, thus turning the cable drums, wrapping the cables around the grooves on the cable drums.

As the spring unwinds and its torque decreases, the chain winds back onto the mainspring barrel and pulls on an increasingly larger diameter portion of the pulley.

Mason didn't want to be around when Blues let that spring unwind.
