ASTRON 113: Introduction to Astronomy

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 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 optical phenomena involving a cat, a converging lens, and the creation of virtual and real images.

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.

Discover electromagnetic induction with a rotating wire loop! In this video, we explore how a 12.0-cm-diameter wire loop generates an induced emf when it's aligned with a magnetic field in 0.20 seconds. Dive into the world of electromagnetic phenomena and uncover the average induced emf.

Discover the key reasons why measurement standards rooted in laboratory procedures offer advantages over standards based on specific objects, like the international prototype kilogram. Dive into the world of metrology and standardization in this informative video.
