PHYS 716: Quantum Field Theory II

Explore the fundamental concept of work in physics and discover the key conditions, including movement, net force, opposing force, and direction, that must be met for work to be accomplished when pushing on an object, such as a rock.

Join us in exploring the fascinating world of vectors and vector addition. In this video, we answer a fundamental question: Can two vectors with different magnitudes ever sum to zero? Delve into the principles of vector mathematics and discover the insights behind this intriguing concept. Tune in for a mind-expanding journey through the world of mathematics!

In this video, we explore the concept of time and distance as we compare two cars traveling at different speeds along a straight highway. We'll calculate when the faster car arrives at a destination 16 km away and find out how far they must travel for it to arrive 15 minutes before the slower car. Join us for an engaging journey through the world of physics and velocity!

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.

Uncover the secrets of watch crystals in this video! We convert the frequency of a quartz crystal used in electric watches into its period. Join us to explore the principles of timekeeping and crystal oscillations.

Discover how to calculate the latent heat of fusion of mercury using calorimetry. Grasp the role of thermal equilibrium in heat transfer calculations. Derive the value of mercury's latent heat of fusion based on experimental data.
