Astronomy Cast Ep. 181: Rotation

<p class="p1"><a href= "http://www.astronomycast.com/archive/">http://www.astronomycast.com/archive/</a></p> <p class="p1"><strong>From March 15, 2010.</strong></p> <p class="p1">Everything in the Universe is spinning. In fact, without this rotation, life on Earth wouldn’t exist. We need the conservation of angular momentum to flatten out galaxies and solar systems, to make planets possible. Let’s find out about the physics involved with everything that spins, and finally figure out the difference between centripetal and centrifugal force.</p> <p class="p2"> </p> <p class="p1">We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.</p> <p class="p1">Just visit: <a href= "https://www.patreon.com/365DaysOfAstronomy">https://www.patreon.com/365DaysOfAstronomy</a> and donate as much as you can!</p> <p class="p1">Share the podcast with your friends and send the Patreon link to them too!</p> <p class="p1">Every bit helps!
