Physicswalla AI is a Generative Pre-trained Transformer (GPT) that serves as an artificial intelligence-based Physics tutor, dedicatedly designed to assist Class XI and XII students, as well as those preparing for competitive examinations like JEE and NEET. This tool is developed by Praveen Kumar P S and is an offering available on the ChatGPT platform. The primary goal of this GPT is to leverage the power of AI to elucidate complex concepts in Physics and to provide educational support tailored to the individual needs of the learner. The utility of Physicswalla AI goes beyond traditional teaching methods as it can provide explanations on a myriad of Physics topics. It provides help with understanding core Physics concepts such as Newton's laws of motion, the theory of relativity, and quantum mechanics, among other topics. It can also assist students in performing calculations related to Physics, for instance, determining kinetic energy. A notable feature of this GPT is its capability to bring years of teaching experience into the interaction, thereby mimicking the assistance one might receive from a seasoned Physics teacher. In a new era of remote teaching and learning, Physicswalla AI represents a paradigm shift in how students could approach the subject of Physics, where learners can, at their convenience, seek clarification or further explanations on topics that are traditionally found to be challenging. Overall, Physicswalla AI could be a helpful tool for any student, providing them with seamless 24/7 access to a 'digital Physics teacher'.
