The discussion centers on the distinctions between periodic motion, oscillatory motion, and simple harmonic motion (S.H.M). It is established that oscillatory motion is a subset of periodic motion, characterized by acceleration that is directly proportional to displacement. The conversation highlights the confusion in differentiating between these terms, particularly in relation to their definitions and characteristics. Participants emphasize the importance of understanding the mean position in S.H.M and its relevance to oscillatory motion.
PREREQUISITESStudents studying physics, educators teaching motion concepts, and anyone seeking clarity on the differences between periodic and oscillatory motions.
yeah my textbook gives it a definition, the definition mentioned in the question the definition of the oscillatory motion , but i know that oscillatory motion is a special case of periodic motion . in addition that in S.H.M the acceleration is directly proportional to the displacement. but the S.H.M has also a mean position like the oscillatory. that's why i can't decide which is answer is correct.berkeman said:Welcome to PF.
Does your textbook give definitions of each? If not, have you looked online (like at Wikipedia) to see what the common definitions are?
It is unclear where one choice ends and the next begins.abdsaber000 said:
