Vibration (also known as oscillation) is a process of state change. That is, the reciprocating motion of objects.

stay High school physics It can be used for quantitative research Formula method There are only four simple methods of drawing uniforn variable rectinear motion Uniform circular motion Projectile motion and Simple harmonic vibration

Complex sports can be carried out by relying on these four kinds of sports Qualitative research

If we insist on quantitative study of complex motion, we should also rely on these four kinds of motion to do approximate research.

Of the four simplest sports, uniforn variable rectinear motion And the projectile motion is a "gone forever" motion, motion state The relationship between (position, velocity) and time is topological (one-to-one correspondence) and can not be repeated.
