What is Inertia?

One of the most fundamental ideas physics students are introduced to is "inertia." Unfortunately, many students misunderstand the concept. This video should set the record straight.

I like how your main point is that inertia is what remains when all forces are removed. Nicely done.

[physicsno]

I'm not lazy, I'm just addicted to inertia.

Never thought physics would be entertaining, this really needs more subs.

So one day, my mom was driving me home from school and my big calculus textbook was on the floor of the van between our seats. She accelerated a bit hard into a left turn from an intersection and the book slid back and to the side, ending up at the side door. I tried to use this as an opportunity to explain inertia to her by explaining that the book didn't move, the van moved while the book stayed stationary.

That was when I was 16. I'm 32 now, and to this day "the book didn't move" still triggers her.

Just wait, this channel will have 100K+ subs in 1-2 years. Keep it up, your content is great!

[erichall]

You're a star sir. Don't stop. You make advance whatever it is, enjoyable, edifying and entertaining as all hell. Etothe3rdpower aka ecubed
Don't stop the world needs you!

[MikesCarInfo]

Great channel! Thank you for all the hard work :)

[landlockedviking]

with out friction the car couldn't have got going either...

[SyFQX]

Dope last name Mr Nick Lucid. Your vids are great! Hope to see this channel accelerating into greatness.

[andrewpaige]

Hi there, thank you for making science and physics more explainable in layman’s terms for the not so nerdy / Einstein minded people who are to embarrassed to ask without some lame ass mocking them. Thank you again and definitely subscribing to your channel and on a mini binge watching session. Cheers from down under Sydney Australia 🇦🇺

I remember finding your channel through this video, while I was studying on an online school. I discovered you several years back when you had like 10, 000 subs. It's nice to see that several years later, you now have over 600, 000.

I would just like to say that in some reference frames it might make sense to interpret inertia as a force, mainly accelerating reference frames and rotating reference frames.

[itskelvinn]

I just had to say this. Aristotle has the emphasis on the TOT syllable.

I love your videos mr lucid ❤️

[MelloCello]

Now I'm starting to realize the importance of, in a straight line, in alot of these readings, because apparently, things start to change the moment you begin to curve

"Inertia is not a force, I repeat, Inertia is not a force... when you take all the forces away, inertia is what remains"

Craziest mic drop statement I've seen in all physics videos

[jmspeedcubing]

Brilliant as always. Love the comment responses at the end!

[otakuribo]

"THE BALLS ARE INERT."

"Does that mean they don't work?"

"No, Gohan. It means the Dragonballs have no energy as we observe them from our inertial frame of reference."

"Well, what does THAT mean, Piccolo?"

"Shut up and watch Science Asylum!"

[theophilus]

So, Aristotle wasn't _entirely_ wrong, then. He was just only _half_ right. Not bad for someone living around two millennia before Newton, I think.

Another point. Modern mechanics may be said to have got really underway with Galilieo and Newton, but there was certainly scientific investigation and experimentation going on before then, including the appliance of mathematics to nature, both in the ancient pagan world and later in Latin Christendom and the Muslim world - and I do not refer to alchemy or astrology and the like.

'The Science Asylum' is a brilliant channel. Of all the popular science channels on YouTube, it has clarified best a number of things that I, as a non-physicist, did not quite grasp. Thank you. That is its strength. However, I might suggest that it leaves history to the historians.

[robertrauch]

Aristotle's legacy is as the father of logic - that contradiction is forbidden. It is the single most important idea any human has ever had. It is the basis for mathematics which in turn gives the basis for science. But Aristotle himself had trouble following his own law and so had a lot of junk ideas.

[bonemasterj]

"..taking all the forces away, what's left is inertia". But inertia also appears to be directly related to the sum of all the previous forces acted upon an object. Inertia is an artifact of previous forces.

Awesome channel, I enjoy al your videos. You deserve many more subscribers!
