Special Relativity Summary and Relativistic Momentum Transformation by Lorentz | Doc Physics

Momentum is still conserved, it's just not what you thought it was. Or maybe it is...if we REDEFINE MASS, SUCKA!

M TIMES V, JUST A LITTLE MOMENTUM. Comment if you've heard that little ditty.

You just explained to me in 12 minutes what my physics 12 book has been trying to explain to me for the last 20 pages... We need more you in this world.

[DocSchuster]

That was absolutely part of my plan. Do you believe me?

Really, that's just one perspective, but I like it because it preserves Newton's 2nd - everyone's favorite law.

I really don't know why your videos are not popular!! So far, your lectures have been the best on youtube!! And the way you try to explain makes everything not easy, but much easier than what I have seen in class recently! Congrats!

[Crosshill]

the energy in this video is refreshing during long grindy sessions, i hope these videos will do the trick for me

[rpnzlhx]

This is amazing...the way you are explaining it and how i could get it just clearly! love it, amazing explanation right here! thank you.

[pooh]

You are an EXCELLENT teacher! Thank you for taking the time to record these videos and putting them on the Internet. My current Physics teacher has trouble explaining concepts and these videos helped me a lot. 

[monder]

Thank you so much Doc! after all these years i still come back and watch your videos.

Love this guys vibe, wish some of my physics profs were like this

[dashama]

Loved your video!

Blessings and Love,

When an inductor discharges its signal loss follows the increments 63.2%, 86.5%, 95%, 98.2% and 99.3%. Which expressed as fractions are 3/4, 1/2, 1/3, 1/6 and 1/9( with a slight error due to an unknown anomaly). The inductors signal and light are both electromagnetic phenomena. There may be a correlation between the two. This brings into play the generation of heat which could destroy all your predictions as the mass will eventually be destroyed. In the same way an electron and positron will destroy themselves if they collide.

How can Preal = gamma*mv if Preal = (m0/gamma)*v? they give different answers

[smokeythebear]

you really made me understand this so much better

[emiliovaleriopadilla]

Where can I get some more special relativity problems(if possible with answer)?

[whitneyst-marseille]

You definitely just saved my physics project.

[DocSchuster]

That's ridiculous. For whom do you you work?

[ABeardedDad]

So would I be correct in deducing that you have explained in simple terms here why your mass increases as your velocity approaches the speed of light???

[tomnoyb]

Nice, couple decade-late questions? 1) A single proton accelerates since the Big-Bang toward earth, missing by a few-hundred kilometers, with a gamma of 10^57, giving it the relativistic mass of the sun. What happens as the proton's massive gravity passes earth? What if the proton hits earth with its massive inertial mass? 2) Relativistic energy plot? 3) Imaginary continuation of the plots?

[AstrophysicistBryan]

In a previous video, you mentioned "Proper Time is the time measured by someone at rest relative to 2 events"...you also explained the Proper Length :-)....

However, what is "rest mass"....rest relative to which observer?...so what is rest mass? vs relativistic mass - thanks

[raziel]

Understand I have a limited concept of all this so excuse my question. Hopefully it is not basic to the point of being stupid.

I am beginning to see the relationship between the speed of light and uncountable infinity. The reason we cannot reach the speed of light on paper is because we can always count a smaller unit of measurement.

If this is true then how is it that we can quantify the speed of light but not infinity?

Is this because of our location as an observer to both of these concepts?

And what does this say about light's observation of infinity?

I learn more from you than my professor
