what are harmonic motion, anharmonic motion, periodic motion, aperiodic motion?
what are the characteristics of these motions?
What are the examples of these motions?
What are the differences between these motions?
2. Periodicmotion
Motion repeats after a definite time
Mathematical Description can not be
generalised
Mathematical description will vary
from case to case.
In some cases the motion can be too
complex to describe.
Time period can be measured
empirically
3. HarmonicMotion
Motion repeats after a definite time
Mathematical Description can be
generalised by a first order theory
Can be described by a sine and / or
cosine function
Motion is generally not complex
Occurs in a ideal / controlled
environment
4. AnharmonicMotion
Motion repeats after a approximately
fixed time interval
Mathematical Description can be
generalised
Mathematical Description can be
generalised by a higher order theory
Accurately describes real world
situations
5. Aperiodicmotion
Motion does not repeat after a
definite time
In Most of the cases the motion can be
too complex to describe.
Concept of time period does not arise
