PHYS 175000: Stars, Galaxies, and the Universe

Explore the fascinating world of friction in motion! In this video, we delve into the concept of frictional forces as we examine a crate being pushed across a factory floor. We'll calculate the magnitude and direction of the frictional force and uncover its role in maintaining constant velocity. Discover the science behind everyday motion.

Discover how to optimize the launch tube acceleration to achieve the maximum height and earn the most points in your laboratory experiment.

Explore the profound link between these two fundamental concepts in physics, and understand how they relate through the Work-Energy Theorem.

Embark on a celestial journey! In this video, we calculate the altitude above a distant planet's surface where a starship orbits. Discover how astronauts experience reduced free-fall acceleration and the fascinating dynamics of space travel.

Uncover the fascinating science behind peephole lenses, including the principles of light refraction and observer positioning that allow for an extensive field of vision through a hotel room door.
