Physics teacher | Tutor for 8 years
With a passion for unraveling the mysteries of the universe, I hold a degree in Physics from Illinois Wesleyan University. I'm dedicated to fostering a deeper understanding of the cosmos through engaging teaching methods. Whether it's classical mechanics or quantum theory, I strive to make complex concepts accessible to all students. My goal is to inspire curiosity and ignite a lifelong love for learning in each individual I teach. Together, let's explore the wonders of the physical world.
Questions
What does the slope of a distance-versus-time graph represent?
