I believe they use some type of spring which is compressed as the handle turns. Naturally, when you let go the spring try's to return to its original position. However, I'm not sure exactly how its done, because most wind up toys make some sort of noise, I would have to take one apart and see what devices are used.

Part-way there..... but be VERY careful if you dismantle anything driven by clockwork because the driving-spring is very powerful and if it is still partly wound up but you release it suddenly by not knowing what you are doing with it, it can bite, potentially seriously such as an eye injury. Clockmakers use special tools and wear eye-protection to deal with these things.

The mechanism is called a Clockwork Motor, because it uses a roughly similar motion to a spring-driven clock. The spring is very long strip of spring-steel wound into a coil further tightened by the winding-key. When the toy is released, the spring unwinds steadily, driving the toy along or around through a train of intervening gears. There may be some form of governor, perhaps just a "fly" (a small fan), to control the rate.

The original "wind-up" gramophones, now antiques, use a high-quality version of the clockwork motor fitted with a sensitive governor to keep the playing speed constant within fine limits. Music-boxes have a compact little clockwork motor to rotate the pin-barrel against the spring-steel comb that it plucks to produce the notes. You can now buy clockwork radios - invented I think by James Dyson - in which the motor drives a small dynamo.
The magnitude of the displacement of the windup toy is zero. Since it starts and ends at the same position, the net change in position is zero, resulting in zero displacement.
A windup toy typically uses a combination of a wheel and axle for movement, gears for transferring rotational motion, and a spring for storing potential energy that is released as the toy walks or moves. These components make it a complex machine rather than a simple one.

When a wind-up toy is released, the potential energy stored in the compressed spring is converted into kinetic energy, causing the toy's moving parts to start moving as the spring unwinds. This kinetic energy drives the motion of the toy until the energy in the spring is fully depleted.
The player had to windup before the game was finally starting.
The most iconic children's bath toy is a rubber ducky that floats on the surface of the bath water. Other examples are waterproof plastic books, flotable plastic blocks and rings, toy boats, swimmers and toy fishes (sometimes mechanical, electrical or windup).
Windup radios are just as the name says: they are radios in which you would crank a handle on the side going in a circular motion. this then charged the radio so that it would work. so you would windup the radio
