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:
Develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy.
Energy
Students who demonstrate understanding can:
Develop and use models to illustrate that energy at the macroscopic scale can be accounted for as either motions of particles or energy stored in fields.
