Potential energy.
The potential energy of a spring is defined by this equation: U=.5kx2 U= potential energy (in joules) k= the spring constant x= the displacement of the spring from equilibrium. (the amount that the spring is stretched or compressed) This equation tells us that as a spring is compressed by a distance x, the potential energy increases proportionately to x2
This is known as elastic energy. It is a type of potential energy.
Elastic energy - which is a type of potential energy.
kinetic energy
Let's say you compress the spring. Work (mechanical energy) is required to compress the spring; this energy is stored in the spring and can be recovered (converted to another type of energy) when the spring returns to its normal position.

mechanical potential energy
kinetic energy
A spring or tensioned system can hold and deliver power. A weight on a line can store and supply energy. Compressed gasses are a source of energy. Wind and water power have been used for thousands of years by mankind to do work.

Let's say you compress the spring. Work (mechanical energy) is required to compress the spring; this energy is stored in the spring and can be recovered (converted to another type of energy) when the spring returns to its normal position.
That's called elastic energy, and it is a type of potential energy.
potential
Simple Version:The energy in a sound wave is mechanical, being both kinetic and potential energy associated with the air.Explained:Just as in a vibrating spring, the medium (air) 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. (The air is compressed and expanded in a sound wave.)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.
