Kepler’s Second Law of Motion - Equal Area in Equal Time (Astronomy)

[@saraiflores3351]

I'm taking an Astronomy course and it is quite difficult for me to understand certain topics but your videos make it much simpler and easy to understand the lectures. Thank You!!!

[@Socratica]

+Sarai Flores That is wonderful to hear! Thank you for watching, and good luck with your course! :)

[@majidkhokhar3833]

Sarai, which course are you taking? I have to take one as well

[@DamianRene]

I can't understand how this amazing editing and unique science videos have too few views..

[@thegoodlydragon7452]

Damian Rene That's what I was thinking. There's clearly a studio and some sort of professional animator using software that might have cost a pretty penny. It's not just a marker on a white board. I'm surprised there are so few views. There's no way she's making a profit off the ad revenue; at most breaking even.

[@Elidoransgar]

@@thegoodlydragon7452 It's very well made. I wish it was more popular. She's an excellent speaker, and judging by her hands, she's part Italian.

[@844SteamFan]

@@hopeastrays lol I have to watch this for a class.

[@vanphatphan6709]

@@thegoodlydragon7452 200k views now, I'm glad to see it picked up. But I only found and watched this video because I want to understand more about Kepler law when studying my physic class.

[@ayeshaiffat8763]

Better than wasting hours in the textbook Made my Day

[@eljison]

Hours in your textbook are not wasted. They help you in a different way and provide practice problems. Videos help condense the information and make it more approachable. If you go back to the textbook after watching the video, it will make more sense to you and help solidify your knowledge.

[@masummoshi3763]

Hi

[@aneeshparasnis5001]

What I am puzzled by is how he measured the area covered in specific amounts of time while covering specific distances..because calculus was only invented by Newton who was definitely born about 90 years after Kepler

[@milanstevic8424]

you don't need calculus to compute the area of a triangle. in classic geometry A = h * b / 2 or in terms of linear algebra A = ||a x b|| / 2

[@kamsochukwuejikeme510]

THANK YOU SO MUCH!!!!!!. YOU HAVE JUST SUMMARIZED THE WHOLE LAW FOR ME TO UNDERSTAND.

[@berlini3760]

thanks for making astronomy videos guys, I really loved this one :D

[@PiotrMagpie]

I love what you did to Kepler Eyes! It scared me at first moment! : D

[@kushalsaitia971]

The background music, the narration and animations are enough for people not at all interested in Astronomy( flat earth society) would even binge watch this series. Coming to my second point: They are so binge worthy!!

[@expl1citken582]

The channel explains the laws and phenomenas so well. It sucks that it has so less views.

[@chan6708]

did u saw that both the eyes of keplers and bronche were moving

[@Socratica]

hehe we hoped someone would find that! :)

[@rajanip2273]

it is

yes ..i thougth in the begining mine having prob.

[@boofang10]

Once again, brilliantly explained.. with the perihelion & aphelion. Definitely going to help my students understand better

[@sarahdiehl2672]

This is so helpful! Textbooks word things so complicated. Thanks for making these concepts easy to digest and understand 🙌

The angle covered in unit time would vary, as seasons change over shortened transition periods.

[@ShamsThoughts]

Thank you. Your videos are really helpful. I don't imagine that physics can be this easy and simple in such a story way ;)

[@cppdev2729]

beautiful explaination 🧡💛💚💛🧡❤🧡 a million times love for this best explaination

[@jimkeller3868]

I've never fully come to terms with this law. Did Kepler start out by somehow observing that the areas swept out indicate the changing distance? That can't be, since in order to determine the area one must already know the distances. So,did he arrive at equal area first, and then arrive at the conclusion that a planet must change speed? This seems specious, since changes in speed of a planet are easily observable against the background stars. Aren't the crucial points the changing speed and the changing distance? What good is it to know anything about area? How did knowing the area swept out serve Kepler? It seems to me that in order to determine the change in distance, and the change in speed of a planet, area is superfluous. And if you suggest that you must know the area in order to calculate speed or distance, I will ask how and why?

[@Hybe123]

Yeah, the area explanation makes no sense. Btw. if an orbit was eliptical, the farther the object went the slower it would appear to move in the sky on top of it actually moving slower. All the area-time jargon is unnecessarily complicating things.

[@PranayBrajabashi]

Getting some Star Trek vibes from these vids. Very informative!

[@maujo2009]

I want to prove 2nd Kepler's law to my students without using math, but I couldn't find anything online :-( Your animation is very helpful though, so I'll show it to the class. Thank you!

[@Socratica]

+Mau Jo We're so glad you are finding our videos helpful! We are working on Kepler's 3rd law right now, so hopefully that will come in handy as well! Thanks for watching and commenting, and thanks so much for sharing with your students! :)

[@TipoQueTocaelPiano]

Without using maths... Good luck

[@josephwagner2030]

I couldn't pay attention to the video on first viewing because I was too preoccupied with whether or not I was hallucinating the subtle movements of the paintings of Kepler and Brahe. Speaking of physical laws, Tycho's mustache seems to violate a few of them.

[@dionsilverman4195]

It would be really cool if there was a derivation of the equal area in equal time law.

[@jbjb3410]

Maybe just a coincidence that speed also seems to increase going into sharper turn of ellipse revolution just like driving your car into a sharper turn,.

[@kirbymarchbarcena]

This is just one of those significant laws in astronomy

It is really very helpfu u have seriously done a very great work!!! Thank you :D #socratica

[@bmilano1580]

finally calculus making sense thanks to the elliptical orbit of Mars!

[@mvenky740]

Thank mem

[@PrateekJain-pi9jc]

I have a question, Does the elliptical orbit have an effect on the seasons on earth (as in the earth is closer to the sun at one end of the orbit than at the other) or is the eccentricity so small that the effect is negligible?

[@Socratica]

This is such an interesting question! Because the Earth's orbit is not very eccentric, the effect is probably negligible. But the degree of eccentricity changes over time - from almost circular to more dramatically eccentric. So during those more extreme times, it's possible that there would be more of an observable effect.

[@micah6330]

1:04 I don't get why there are 2 lines pointig to the Sun. It says if you draw "a line", which is the line from the Sun to Mars, there should only by 1 line, but I see there are 2.

[@pankajdharnia672]

How Kepler's 2nd law is based on conservation of angular momentum please explain in brief.

[@alphalunamare]

Brilliant ..so 1st law is geometric ... 2nd is 'dynamical'. I never realised that.

[@yaronkl]

Smart man. To me this is a big a discovery as special or general relativity.

[@abhishekvishwakarma6865]

Thanks, your all videos are very helpful for my study.please explain (Newton's law of gravitation)

[@sujoyghosh8612]

Ma'am I am Shinjini Ghosh from India. This video is very helpful. But I as I was going through my text book I had a problem. I am a student of class 9. In my book it is written that Gravitational force between two bodies act as action reaction pair . But my question is that when we draw the free body diagram of a body we always give the gravitational force downwards. In my book it is written that the force required by a planet to move around the sun in elliptical path is provided by the gravitational force of attraction between the planet and the sun . How is this possible?? I would be very grateful if you could explain this to me.

[@jogendraverma1135]

Thanks mam

[@moonlightsamuel4073]

Man I've started loving physics 😋😝😝♥️

If I gave you an elliptical pizza, would you be able to slice it into equal areas from one of the focal points?

[@bablookumar4019]

the part where the demonstration actually starts and it's written kepler's second law.. the music which is played, is it from a movie? I think it is.. If anyone finds out please tell

[@sejalkumar5541]

Love you and your video I am from India .. i love the things going easy to me please reply me.... That you will make a video on fluid in physic

[@megscorner3596]

Does this apply for all planets that travel elliptical paths?

[@denied2423]

Kepler's area law is false: he estimate r*Vp=Costant.While Newton law says: attraction force is radial,a perpenendicular attraction force componenet deos not exist.So,m*dVp/dt=Fp=0 means Vp=Constant.Only.

[@echoow]

thank you for explaining this like an actual normal functioning human being with a competent brain

[@abhishekmalik9231]

How is velocity constant in a circular motion what about the tangential acceleration??

[@MS_PrithwirajMaity]

what softwere you use to animate and vizulization pls pls tell mee?

[@Socratica]

We mainly use the Adobe suite of software - Premiere and After Effects. We're self-taught filmmakers so we are still learning!

[@rayagoldendropofsun397]

There's s reason why planets and others orbit solely on the orbital plain, it's because they find more ENERGY to conserve, which keeps them in their orbit .The Sun has an uneven SUNLIGHT ENERGY FLOW, with the mother load of Sunlight shaft coming directly to the orbital plain, where energy conservation determines planetary orbit with maintenance and upgrades in real time as needed. The Sun is an outward ENERGY FLOW, and has no inwards pull on any object . They all keep and maintain their orbit by conserve energy in real time .

[@shendy8104]

What is the purpose of kepler's third law?

[@DatGuy-jz3se]

Wow this helped me a lot thanks, I was just looking at the definition of the second law and looking at pictures of the area and didn't understand it completely.

[@Socratica]

That's wonderful to hear! Definitely, we find that sometimes a video can really add to our understanding. Thanks for watching! :)
