Скачать или смотреть The Physics of Pulling a Pole: Instant Yank or Not?

Have you ever wondered what would happen if you pulled a metal pole stretching from England to France? In this video, we explore the fascinating physics behind this hypothetical scenario. When you yank one end, does the other end move instantly? Get ready to dive into the world of sound waves, the speed of light, and the surprising behavior of solids on a microscopic level.
Discover why our intuition about solids might lead us astray and how sound travels through different mediums at varying speeds. We'll calculate the time it would take for a signal to travel from one end of the pole to the other, and compare it to the mind-boggling speed of light. Get ready to challenge your understanding of the universe's fundamental rules!
