- | The simplest mechanical oscillating system is a mass attached to a linear spring subject to no other forces.
| + | |
- | Such a system may be approximated on an air table or ice surface. The system is in an equilibrium state when the spring is static.
| + | |
- | If the system is displaced from the equilibrium, there is a net restoring force on the mass, tending to bring it back to equilibrium.
| + | |
- | However, in moving the mass back to the equilibrium position, it has acquired momentum which keeps it moving beyond that position,
| + | |
- | establishing a new restoring force in the opposite sense. If a constant force such as gravity is added to the system, the point of
| + | |
- | equilibrium is shifted. The time taken for an oscillation to occur is often referred to as the oscillatory period. </p>
| + | |
- | <p>The specific dynamics of this spring-mass system are described mathematically by the simple harmonic oscillator and the regular
| + | |
- | periodic motion is known as simple harmonic motion. In the spring-mass system, oscillations occur because, at the static equilibrium
| + | |
- | displacement, the mass has kinetic energy which is converted into potential energy stored in the spring at the extremes of its path.
| + | |
- | The spring-mass system illustrates some common features of oscillation, namely the existence of an equilibrium and the presence of a
| + | |
- | restoring force which grows stronger the further the system deviates from equilibrium.</p>
