spinning causes planetary perturbations as the planets revolve around sun.
In general a wave is a possible mean a perturbation propagate. In classical physics linear perturbation essentially propagates only by waves or by diffusion. As examples, a pressure wave, like a sound wave, is started in a solid by applying a time dependent pressure in a point of the solid. An electromagnetic wave, like those used by cell phone to contact each other or by radars to individuate objects, is created by moving charges that introduce a perturbation in the electromagnetic field.
Roughly speaking, a body will be stable if its center of gravity, projected downward, is inside the surface on which it rests.
Study of matter is Physics, study of energy can be Physics or Thermodynamics

The doctor says, "A great perturbation in nature, to receive at once the benefit of sleep, and do the effects of watching!". "Perturbation" means a disturbance, and to the mind of the doctor, the disturbance in nature is the fact of sleepwalking, where one can be asleep but act as if one is awake. The perturbation in nature does not cause the sleepwalking, it IS the sleepwalking.
Perturbation is a noun for anxiety or mental uneasiness; a cause of anxiety or mental uneasiness; or a deviation of system or moving object from its normal function or direction. Example sentence:His perturbation was a telltale sign that anyone could recognise and respond to.
A perturbation function is used in mathematics and physics to represent small changes or disturbances to a system's parameters or variables. It helps in analyzing the effects of these perturbations on the overall behavior of the system.
