ASTR 170: Astronomy: The Physical Universe

Explore the fundamental principles of this law, unraveling its implications, and clarifying common misconceptions related to mass preservation in chemical reactions.

Uncover the secrets of watch crystals in this video! We convert the frequency of a quartz crystal used in electric watches into its period. Join us to explore the principles of timekeeping and crystal oscillations.

Discover the incredible tale of David Purley's survival in a high-speed car crash! In this video, we calculate the magnitude of the acceleration he experienced during the rapid deceleration from 173 km/h to zero. Learn how to express it in units of gravity and explore the limits of human endurance.

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.

Explore the world of thermal insulation and heat loss in this video. We compare single-pane and double-pane windows, calculating the heat loss ratio. Delve into the fascinating science of heat transfer and insulation factors. Join us to uncover the secrets behind energy-efficient windows.
