PHYS 221: General Physics 2

Explore the relative strengths of two fundamental forces, the electromagnetic force and the gravitational force, in this enlightening physics tutorial. Learn about Coulomb's law and Newton's law of gravitation, and uncover the significant difference in their constants that makes the electromagnetic force much more powerful than gravity.

Join us as we explore the dynamic world of gymnastics and the forces at play. In this video, we analyze a gymnast's routine on the rings, calculating the forces involved. Learn how the gymnast's body interacts with the rings and the floor, and discover how changes in arm angles affect the forces. Dive into the physics of human movement and gymnastics.

Explore the fascinating world of light coherence! In this video, we examine various pairs of light sources to determine their coherence. From candles to reflections in mirrors and soap films, we unravel the concept of coherent light sources.

Discover the significance of models in the fascinating realms of relativity and quantum mechanics, where conditions defy our everyday experience. Explore the concept of a model and its role in understanding these complex theories.

Join us in exploring the concept of significant figures in numerical values. Learn to identify and count significant figures in various numbers, from whole numbers to decimals. Understand the precision and accuracy of your measurements through this engaging video.
