Development of a Web-Based Virtual Laboratory for the Study of Simple Pendulum Using HTML

Virtual laboratories have emerged as an effective pedagogical tool for enhancing conceptual understanding and experimental skills in physics education. In this work, a web-based virtual laboratory on the Simple Pendulum has been developed using HTML and deployed through Google Sites. The virtual lab allows users to vary key physical parameters such as length of the pendulum and initial angular displacement, and to input experimental data through a structured data table. Based on the user inputs, the system computes the time period of oscillation or the acceleration due to gravity (g) using standard theoretical relations. This virtual experiment replicates essential features of a real pendulum experiment and provides an interactive, accessible, and cost-effective alternative to traditional laboratories, particularly useful in blended and remote learning environments.
