Glossary of Key Terms

• Alternating Current (AC): An electric current that periodically reverses direction and changes its magnitude continuously with time. It is commonly represented by a sinusoidal waveform.
• Average Power: The mean value of the instantaneous power over a complete cycle of an AC signal. For a sinusoidal AC circuit, it is often expressed in terms of RMS values of voltage and current and the phase angle between them.
• Amplitude: The maximum extent of a vibration or oscillation, measured from the position of equilibrium. In the context of an AC waveform, it is the peak value of the current or voltage.
• JavaScript: A high-level, often just-in-time compiled language that conforms to the ECMAScript specification. It is a programming language that makes web pages interactive.
• HTML5: The latest evolution of the standard that defines HTML. It describes the structure of web pages and includes technologies that enable richer web applications and multimedia without the need for plugins.
• Applet: A small application, especially one intended to perform a single task and often run within a larger application (like a web browser). In this context, it refers to the interactive simulation itself.
• Open Educational Resources (OER): Teaching, learning, and research materials that are freely available for use, adaptation, and sharing, often under an open license.
• Open Source Physics (OSP): A project and community focused on creating and disseminating open-source computational tools and resources for physics education.
• Simulation: A computer-based model of a real-world system or process, used to explore its behavior and characteristics through interactive manipulation of variables.
• Interactive: Allowing for real-time input and response between the user and the system, enabling active exploration and learning.
