Why Are Airplane Engines So Big?

The physics behind the perfect size of a jet engine. Thanks to http://www.audible.com/minutephysics for supporting this video – if you try the free 30-day trial, I recommend "Ender's Game" by Orson Scott Card Thanks for everyone who supports MinutePhysics on Patreon! Link to Patreon supporters here: www.minutephysics.com/supporters.html The answer to this question has everything to do with drag & kinetic energy vs momentum change (thrust) – ie, a bigger engine fan allows for a larger air mass to be accelerated a smaller amount to give the same thrust as you’d get from a smaller engine with larger acceleration. Any acceleration of air imparts energy to that air, which is in principle wasted energy, so ideally we minimize the acceleration of air while maintaining constant thrust, aka bigger engine fan. However, bigger fans have more drag, so there is an ultimate size limit.

Why It's HARD To Land on Mars
 
02:02
Support MinutePhysics on Patreon! http://www.patreon.com/minutephysics This video is about why it's harder to successfully land spacecraft and landers and rovers on Mars than on Earth, or Venus, or the Moon, or Titan, or asteroids. It all comes down to atmospheric density! When there's no atmosphere, you can do a powered descent in a flimsy tinfoil spacecraft like the Lunar Module, and when there's plenty of atmosphere you can do an unpowered descent via heat shield and parachutes like the space shuttle, Apollo command module, Soyuz, Huygens, etc. But on Mars with its thin air, you have to do both powered & unpowered descent, getting the worst of both worlds.

How Do We Know The Universe Is ACCELERATING?
 
03:27
Support MinutePhysics on Patreon: http://www.patreon.com/minutephysics Aatish Bhatia helped write this video! A big thanks for his help! Here's his blog: http://www.empiricalzeal.com The universe is expanding – this we know from looking at red shifts of distant galaxies – but the acceleration of the universe's expansion is harder to measure. It requires measuring the change of recession velocity over time, and it's done by comparing Type Ia supernovas as standard candles at different distances, which is how we know the universe is accelerating!
