PHYS 115: Principles of Physics II

Discover the magic of total internal reflection in this video! We explore how a ray of light refracts when traveling from glass into water. Find out the critical angle needed for total reflection, preventing any light from entering the water. Dive into the world of optics and refraction.

Step into the showroom as we explore the intriguing connection between rug dimensions and area. Learn whether a rug being twice as long as another implies its area is also doubled. Join us for a comprehensive explanation of this geometric concept.

Join us to explore the science of hand-warming through friction in this video. We calculate the temperature increase as a woman rubs her hands together, converting work into thermal energy. Dive into the physics of heat generation and discover how friction can keep you warm.

Discover the limits of circular motion as we explore the maximum speed a ball can achieve before its string breaks. Uncover the physics behind this thrilling scenario in our engaging video.

Delve into Newton's third law of motion and explore how the choice of the 'system of interest' influences whether force pairs cancel each other out.
