What does it mean to oscillate?

Oscillate refers to the phenomenon of alternating between two different states or positions over time. This can be seen in various contexts, such as in physics where a pendulum swings back and forth, or in electrical signals where the current fluctuates between positive and negative values. The key aspect of oscillation is this repetitive movement or change between two distinct states, which captures the essence of how the term is applied broadly across different disciplines.

Understanding oscillation is important in fields like mechanics, electronics, and even in the study of cyclical patterns in nature. This definition clearly distinguishes oscillation from the concepts of remaining stationary, steadily increasing, or gradually decreasing, which do not involve this inherent back-and-forth movement characteristic of oscillation.
