PHYS 161: General Astronomy 1

Watch as we explore the fascinating world of thermal expansion in this video. We start with a glass filled to the brim with 350.0 mL of water at a scorching 100.0°C, and then witness the magic unfold as the temperature decreases to a cool 20.0°C. But the real question is, how much more water can we add to the glass? Join us to find out!

Illuminate the science of flashlight power! In this video, we explore how a 6V bulb is powered by a 3V battery with an internal resistance. We calculate the power dissipation of the bulb and the terminal voltage of the battery, unraveling the physics of electrical circuits.

Explore the fascinating science of air temperature change in this video! We calculate how the volume of inhaled air increases as it warms from 0.0°C to body temperature. Discover the principles of thermal expansion in the human body.

Explore the physics behind an athlete's rope climb. Understand the relationship between power, force, and time, and how to calculate the minimum power output an athlete exerts. Witness the interplay of physics principles in evaluating athletic prowess.

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.

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!
