The spring is wound tighter, this stores the potential energy. The spring unwinding turns the potential energy into kinetic energy.
No. Its potential energy does decrease.
The energy in a sound wave is both kinetic and potential. Just as in a vibrating spring, the medium has mass and moves and so moving mass is kinetic energy. Just as in the spring there is compression and rarefaction, so there is elastic potential energy. In fact, these two are equal, potential energy = kinetic energy, just like a spring. Just like in a vibrating spring, the total energy is constant and equal to the average kinetic energy plus the average potential energy.

Sound is the movement of a medium at frequencies we can hear. As it always involves movement of a medium, either a solid, liquid or gas to be transmitted it will involve kinetic energy at times. Note that kinetic energy is the energy stored in a moving mass. Sound waves carry energy with a combination of both kinetic and potential energy. There are two moments in every cycle where there is no movement and therefore no kinetic energy. These two points are at the upper and lower peaks of the wave.
uh, down? (yes, down) The potential energy, as in a compressed spring, goes to zero as the spring is released. The potential energy (sort of) becomes the kinetic energy. (Now, I'm sure that that statement could get an argument in the physics study room in the science building, but it'll get you by...)
The mechanical energy is stored in the spring as potential energy within the pullback toy and when you release it, it gets converted into kinetic energy. Hence cycle is Mechanical --- Spring (Potential)--- Kinetic
No, it is called potential energy. When the compressed spring is allowed to expand, then it becomes kinetic energy.
potential
Kinetic Energy = 1/2 Mass * Velocity squared KE = (1/2)mV2 Your stream has mass and, if running, has velocity. So, this would be an example of generated kinetic energy.

Potential energy occurs in a spring when it is stretched because it now has the potential to bounce back with kinetic energy it is said to have elastic potential energy (EPE)

potential
A spring you see in a pen. It has potential energy until you click it, then the coiled spring becomes kinetic.
