Thanks for watching! I'm planning on covering angular momentum soon, but please let me know which other topics you'd like to see a video on! And here's the link to the companion video on some real-world applications of momentum - nebula.tv/videos/the-efficient-engineer-momentum-in-action-realworld-applications

Momentum is explained so clearly in this video. I always struggled to understand how it works in real life scenarios like collisions or rocket launches, but this video really breaks it down. I remember using SolutionInn for physics problems, and videos like this make everything click even more. Loving these simple yet powerful explanations.

[@Vengemann]

I just wanted this kinda video that explains momentum well.. I used to get confused at some stuffs.. this video covered it nicely thanks 👍

Sir , u are doing well .i wish u won't stop making these types of fantastic scientific videos ❤.

[@thehyperfinestructure6550]

Plz make more such videos that explain physics concepts and how they are applied to daily life. I was amazed when you said that the force required to stop a truck is given by the momentum equation: p = mv. This simple application of the equation is just so beautiful!

[@mohamedibrahim1023]

This will be one of the most important videos on this channel( remark my comment) , thank you for these awesome high quality videos

Exceptional and clearly explained. The measurement of Kr - 81 in air was used to determine the extent of nuclear weapon production years ago.

Ill just go ahead and thumbs up right away. Every efficient engineer video is insanely good. 🤷

[@andzhhh]

Such an amazing video!Very educative

[@Nando_Leal]

15:00 Hey guys, I'm an Aerospace Engineer here. The oversimplification of the mass is wrong. The rocket mass reduces over time. The initial mass will not be the same at the V final because the rocket burns fuel and oxidizer masses. In the end, the V final will be higher due to the lower M final.

[@dimitrijestankovic6199]

Yes , that's why we using tsiolkovsky rocket equation.But that's not point in this video.

[@Salien1999]

Over a period larger than 10 seconds (and really in any case if I were doing this for real professional work), I could see having to account for the change in mass. This is an example of weighing what factors do and don't matter when making your model. If I'm just doing some quick math to get an estimate for very early in the launch, I could see neglecting the change in mass and just acknowledging that this results in an underestimate of the rocket's velocity. As the saying goes, all models are wrong. Some are just useful.

[@SageCog801-zl1ue]

Russian rocket designs were very advanced and yet quite simple ​@@dimitrijestankovic6199

[@SageCog801-zl1ue]

​@@SporadicBenevolenceA very good point about fuel expenditure. Energy to mass relation is always a blast.

Danke schoen, Herr Efficient Engineer

[@ramnathnayak284]

Very nice explanation and graphics

[@djt6fan]

I have a very simple request: could you make a short video explaining how differentials and infinitesimals (which don't have a rigorous definition in standard analysis) are intuitively used in physics and engineering? There exists a gap in transition between math courses and physics/engineering courses, and students aren't taught this intuitive usage, but it's everywhere in physics and engineering. Just as an example, slicing up a hoop into infinite small masses dm, in order to take an integral to calculate inertia.

[@TheEfficientEngineer]

Yes definitely planning on covering something similar to this next year! Good to know there is interest.

[@djt6fan]

@@TheEfficientEngineer Awesome, looking forward to it! Cheers :)

[@user-ds4iz7qf6t]

🤯 شما خودت چگونه به این درک از فیزیک و ریاضی رسیدی؟ لطفا تجربه ای که داری رو برام توضیح بده که من هم استفاده کنم، درود از ایران🇮🇷

[@dillegitante]

​@user-ds4iz7qf6tLeibnizian Calculus is very expedient, but not taught. Many mathematicians are bashing it without knowing it enough.

[@djt6fan]

@user-ds4iz7qf6t If this question was directed at me, I am a mechanical engineer (finished university a year ago) so I have had a fair share of physics courses, where calculus has been used in ways I haven’t been taught in the math class. Just as a basic example, math teaches us that when we have a derivative dy/dx for example, that it is not a ratio, and cannot be thought of as such. The precise definition is that a derivative is a *limit* of a ratio delta x / delta y when delta y approaches 0. Yet I would see d theta for a small angle, dm for a small mass, dq for a small charge and so on everywhere used on their own. Then it became clear to me that either the math definitions aren’t correct (they are), or that there must be some way in which physicists and engineers use those differentials differently. Mathematicians will say that physicists and engineers abuse this notation, or that they use infinitesimals, which is a non-standard, albeit very intuitive way of doing calculations. The sad thing is that no one explains this intuitive usage, you just have to accept it. The problem is that this abuse of infinitesimal notation will work just fine with regular derivatives (dy/dx = 4x => dy =4xdx - this is not allowed in math, but is very common in physics), but it won’t work with second or higher derivatives (d^2y/dx^2 = 4x => d^2y = 4xdx^2 - this is completely false).

Please make a video on basic vector calculus used in Fluid Mechanics...

[@xpowerst4534]

Wait at 2:40 you said gravity is canceled by normal force on the road , equal and opposite force but the equal and opposite forces has to be of the same type , so wouldn’t the gravitional force by the CAR would cancel it out ?? I am confused and if i am wrong pls correct me

[@ln7029]

So u mean gravity should be not cancelled here ?!

[@xpowerst4534]

@ it should be but by something else i think

[@wvr7971]

make a video on relativistic momentum and energy

[@davidemartorana4708]

i would love to see a video like this but for enthropy

[@douggale5962]

6:22 v2 is wrong, isn't it? It's not a v either. You are showing speeds and naming them vectors (or worse, velocities?). You need -25 to make that add up to zero. If you don't mean -25, there where do you imply one of the velocities being a negation of the other?

[@TheEfficientEngineer]

For the explosion example I used vectors when developing the equation for v_2, but at the very end I showed the result as a speed because I thought it made more sense to present the result that way (note that I removed the vector arrow from above the v when I did this).

[@j.fabricioelias227]

[@sohamsiddhapura8086]

But why is momentum conserved? Why not kinetic energy for example. At 6:23 why isn’t 1/2 mv^2 the same for both pieces for example?

Force is: F=m*a
