PHYSICS 241: Introduction to Modern PHYSICS

Explore the fascinating world of electric potential as we calculate the value at the center of a circular arrangement of five equally charged particles. Join us for a captivating journey into electrostatics and symmetry in this enlightening video.

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.

Join us in this enlightening video as we explore the fascinating world of projectiles and their optimal launch angles. We dive into the physics behind how a fixed initial speed affects the range of a projectile and why, for most angles, there are two choices that yield the same range. Delve into factors that affect an archer's ability to hit a target, including wind, and learn why a smaller angle, closer to the horizontal, is often preferable. Discover when and why a larger angle may be necessar
