Oscillatory motion is a type of periodic motion where a system moves back and forth around a central position. This type of motion is characterized by a repeating pattern of movement, with the system crossing the central position multiple times over a period of time.
Period: The time it takes for the system to complete one full cycle of motion.
Frequency: The number of cycles per unit of time (usually measured in hertz, Hz).
Simple Harmonic Motion (SHM): A special type of oscillatory motion where the acceleration of the system is directly proportional to its displacement from the central position and is always directed towards the central position.
Mathematical Description
Oscillatory motion can be described mathematically using equations of motion. For example, the displacement of a system undergoing simple harmonic motion can be represented by the equation:
Energy - A. Energy is involved in all physical and chemical processes. It is conserved, and can be transformed from one form to another and into work. At the atomic and nuclear levels energy is not continuous but exists in discrete amounts. Energy and mass are related through Einstein's equation E=mc 2 . B. The properties of atomic nuclei are responsible for energy-related phenomena such as radioactivity, fission and fusion. C. Changes in entropy and energy that accompany chemical reactions influence reaction paths. Chemical reactions result in the release or absorption of energy. D. The theory of electromagnetism explains that electricity and magnetism are closely related. Electric charges are the source of electric fields. Moving charges generate magnetic fields. E. Waves are the propagation of a disturbance. They transport energy and momentum but do not transport matter.
