    • Events Conducted by Physics Club
    The Physics Club organized several events, including an escape room game and a quiz, to promote students' interest in physics. The escape room game challenged participants to solve puzzles and riddles that involved physics concepts, such as gravity and mechanics, to escape from a locked room. The quiz tested students' knowledge of various topics in physics, such as thermodynamics, electromagnetism, and quantum mechanics. Both events were highly engaging and helped to foster a love of physics among the students. The club's events were a great opportunity for students to learn and have fun at the same time, and they were highly successful in achieving their goal of promoting an interest in physics.
