What Is Momentum? (joke video)

My math/physics playlists:

Some people in the comments are prospective physics majors and I just want to make something clear: this video is a joke/exaggeration.

Usually you spend months or years building up to the more complicated physics concepts. And a good prof should never make fun of you for getting an answer wrong. Also, while you may feel dumb at various points in university, I can guarantee your classmates will feel the exact same, so it's a journey you'll be on together.

That said, I think many engineering/physics majors (myself included) can relate to the feeling of spending hours trying to understand something, and still not fully "getting" it. It happens. That's the feeling I'm trying to make fun of here. But it's a normal part of learning and I wouldn't let it discourage you. I've made nearly 80 physics/math videos on this channel and I wouldn't have done that if I didn't enjoy physics!

I have a masters in physics and I can say this is 100% accurate, I'm currently in the frictionless void myself

This had no right being this good. The teacher’s sad eyes broke me. Brilliant story telling

[remixex]

The jump from High School physics to undergrad and then grad school is the ultimate "Those bastards lied to me" story

[BeefCake]

As a recent physics grad and current high school physics teacher, this resonated on levels I can't begin to explain.

This is how it feels for any science subject when you go to university/college. Exactly how it was for me with Maths.

I sent a letter to Dr Feynman when I was a student in a QED class. He actually answered me. I was trying to make sense of mechanism of particles attracting each other since my "physical" picture could explain how they could repel each other. What he told me applies here. All our theories are simply model for the actual universe. If the model give you a result that works, it is a good enough model to use. Therefore, if Momentum equals Mass times velocity works, use it. If not try one of the other models. This same principle applies to all our theories. It's why we can use Newton's equations most of the time and get good answers.

This is what it feels like when you go from popular science books to textbooks.

The biggest joke is that there are 300 people in one class learning about the inertia tensor

[casperes]

I love this academic humour thing. I studied computer science (defending my master's thesis tomorrow) and I felt soooo lost first semester. They were like "No programming background required", so I thought I were ahead already knowing basic programming when I started.... Then they slapped me with linear algebra, set theory, advanced logic, etc. and I realised why programming wasn't a pre-requisite. Programming is a tool for computer science; It isn't computer science itself

[pieguy]

This video got super real for a few minutes and then violently pulled me back into the joke

[kanikapathak]

Feynman: I think I can safely say nobody understands Quantum mechanics.
Eigenchris: I think I can safely say nobody understands Physics.

[milessitcawich]

I keep coming back to this video after learning more physics and see the progress I’ve made

[morganoconnor]

Addition to the end:

Not knowing if you should use the inertia tensor or relativity or linear momentum, you treat your entire mass as a single point particle. This will surely allow you to use linear momentum and you can recapture your childhood pride. You work hard to figure out your position and measure the time change so you can find your velocity. But as soon as you figure out where you are, Heisenberg shows up and slaps you in the face.

Reject physics, return to mathematics.

I'm eternally bouncing in a void with perfectly elastic collision.

"Life is pointless and physics will never make sense no matter how hard you try to understand it" is my current mood.

No one:
Physics: *Momentum* can be whatever I want

"Momentum, a function of mass and velocity, is conserved between portals. In layman's terms, speedy thing goes in, speedy thing comes out."
