About Coil Springs
Oscillating Springs
- When a spring is oscillating up and down it has three important positions:
- Compressed is when the spring is at its shortest.
- Equilibrium is the length that the spring rests when it is not moving.
- Extended is when the spring is stretched to its longest.
Energy Transfers
 |
 |
| As the spring extends from equilibrium, energy is transferred from the kinetic energy store to the elastic potential energy store. | As the spring returns from stretched to equilibrium, energy is transferred from the elastic potential energy store to the kinetic energy store. |
 |
 |
| As the spring is compressed from equilibrium, energy is transferred from the kinetic energy store to the gravitational potential energy store. | As the spring returns from compressed to equilibrium, energy is transferred from the gravitational potential energy store to the kinetic energy store. |
