✵✵✵✵✵ Kepler's First Law of Motion
ELLIPTICAL ORBITS (Astronomy)
With his first law of planetary motion, Kepler rejected circular orbits and showed that an ellipse could better explain the observed motions of Mars. Generalized to all planets, it states that the orbit of a planet follows an ellipse with the Sun at one focus.
Do you know how to draw an ellipse? We show you a neat trick in this video using a piece of string, a pencil, and a couple of pushpins.

Finally i understood the correct meaning of ellepse thank u so much😄
Can we all just take a moment to *WATCH THE VIDEO AND NOT TALK ABOUT HER?!*
Thanks Socratica Friend. We're trying to keep our comment section clean, out of respect for our hosts and our viewers. We regularly delete and block but some people are dedicated vulgarians.
Concentrate on the science, good folks. That's why we make these videos.
Ok
I didn't know it was possible to draw a precise ellipse practically.
Given in ncert class 11 textbook
You are making a difference! This channel is Apple of education... Nice work... Nice efforts.... You spend a lot of time and energy on these videos.... Gr8 value shared...✌️✌️ u will be top channel soon 😘
Mandhan Academy whoa sirrr
Keep up the good work ......
and thanks for your effort
really liked the video
beautiful presentation!
Nice video tutorial! Thank you for sharing
1st april 2017...i found an amazing channel!...please keep uploading..."Socratica"!
This is awesome and the model of drawing a ellipse with 2 pins as focii they have nearly killed it.i subscribed for this channel.
Your videos are really good .. keep the good work
Very clear, Thanks!
Bravissima! 👏🏻
Fantastic explanation, thanks!
Really helped me! Thanks!!
great video keep it up☺
Your concepts are very clear for us
Also thank you for posting this. i had my students watch this before taking a quiz and they aced it!
Thank you so much for sharing with your students!!!
The best video
It was just a awesome explanation
Thanks a lot 😊😊😊😊
Thank you so much.
Thank you ❤️
I actually perform that pencil experiment of forming an ellipse. Thanks for explaining
YOUR ANIMATION IS REALLY COOL!!
you should make more videos about the universe >///////<
im really happy to watch them all~
Brilliant work Ma'am.
I loved the way you drew the ellipse. Brilliant 😍😍
Is there a same way of drawing a parabola and a hyperbola?
real help. just subscribed
Hooray!! We're so glad you found Socratica. Thank you for subscribing! :)
Fabulous activity explanation love teaching like you madam
Nice video, although a few more details about ellipse equations would have been handy. ;)
Appreciate your videos a lot since I have seen so many others about the topic already...
...and could still learn something new from yours! Amazing! 5 Stars!
I noticed that the orbital movements in your videos always show clockwise. So this is more like the view from the south. May I assume that you have chosen a pragmatic simplification because it does not really count from a global perspective anyway?
Or is it the kind of mistake in productions like those where the earth turns into the wrong direction in the background of a newscast?:-)
wow - you do make videos that are beautiful and concise. Hat off to you!
birdtracks Thank you so much for your nice comment! We're so glad you are watching. :)
Socratica it's really beautiful.. really.. great job!
Your ability to teach is very good
Good background with the Geocentric model & Heliocentric model.. leading eventually to the ellipse.. Plus the concept of 2 foci in Kepler's First Law !! 👍🏻👍🏻😁
I needed this so much! thank you, these videos will help me out this semester! subscribing for sure
This is my favorite educational math and physics channel online
Nice content ....👍👍👍
very interesting!!
Thank you! This is a pleasure to watch, also because my english is not perfect! :-)
great video
Pls post some more videos..... It's very easy to learn....you are amazing!!!
More on the way! Thanks for watching! :)

you tell a good story
and the pic are cool
Very good
thank you teacher :D
I approve of this channel name
Tks
Thank you so much for this video, really helped me to understand when my lecturer and textbook let me down. Thanks again!!
I feel there's a parallel between early astromers' desire to have perfect circular orbits, and today's physicists' desire to have supersymmetry in the subatomic world. In many respects, the 'elegance' or 'beauty' motivated both of these, and hindered breaking it to describe what actually happens.
00:37 to 00:41, what made/helped the depiction of galaxies clockwise spin?
Is the depiction true at 2:06-2:10?
Thanks.
awesome
good explain skill
more! please feed me more with astronomy! stuff about black holes and time and stuff please :3
MrFlupsy Thank you for watching! More astronomy videos on the way!
Socratica i dig
That was great miss. Can you give me the derivation of the formulas of the kepler's law?
Tnx
Your videos are awesome can you please make its lyrics for better understanding
Using the pins paper and pencil to come up with a conclusion That's very clever 👏👏👏👏👏👏👏👏👏👏👏👏👏👏
thank you i'm learning about the moon a i had no idea what a elipical orbit was
Liliana, do you do your own animations? i love them, well done
You're so kind, thank you! We're a small team here at Socratica. You can read more about us here:

Can u make a video on the Pauli exclusion principle
I want to do the right thing.
Omg.... thanks so much.Because it helped me a lot to prepare for competitive exam...😍😍😘
Wonderful! Good luck!! :)
Socratica
You are good
where is second focii other than sun in kepler frist law,? and does it play any roll in planetry motion?
Really nice to the point presentation! I have a question that I actually always wonder about.
Something for the science gurus.
Why do planets have circular orbits?
If you play with the math, a speed slightly too slow and it would become an elliptical orbit.
The same for a speed slightly too fast.
So a circular orbit needs a perfect speed.
But, if a comet comes past us, it sucks on our energy.
As we burn energy, we changing the mass of the Earth, and that would speed us up a little, conservation of energy.
Solar winds are pushing us.
So... if left to chance, the probability of have an elliptical orbit is very high.
So, why do we maintain a circular orbit, as all those planets close to the Sun also do.
Something is keeping us circular and the speed perfect... what is that?
0:59 Why is Tycho Brahe moving his eyes from side to side?
Magic😳
Hey, maybe this is a stupid question but what did he actually mean in his law with "...with the sun at one of the two foci" , does it mean that all planets go around the sun (in an ellipse) with either the sun on the left F1 or right F2? Because in all the images (2:10 for example) the sun is for every planet at the left foci?
thanks . your information is more useful .please, explain the binding energy of satellite. please..
......
1:36 cool experiment
Can you please tell me how did you animate the planets going around the sun in an elliptical orbit , im having problem customizing the speed of the planet being faster at periapsis and slower at apoapsis
What program do you use
After effects, premiere pro and hitfilm
from Bangladesh
Very good
I use this video in my lesson to my students and I put a link to your channel and for this video inside my video on my channel
That's so nice of you Mr. Science! Thanks so much for sharing with your students. It makes a huge difference for us! 💜🦉
I HAVE ONE QUE HOW L1 AND L2 contant bcz the distance is changes plzz solve my difficulty
Good
How do you determine a concentric circle from a eccentric ellips?
A circle is a degenerate ellipse :-)
Thank you for sharing
Plantery orbit topic bh explain kr dyn
Good content with a compelling teacher.
will you tell us more about other black hole's theories.....
What does focus 1 and focus 2 mean ?
Thank you, it is implanting an urge to know more about astronomy in me, an electrical engineer....
Circular planetary orbits were hypothesized by Plato in his writings on natural philosophy. They heavily influenced scientific thought for the next 2000 years. Ptolemy had to use deferants and and other offsets to squeeze the planets into circular orbits, although he already had contradictory evidence at hand, which he made available in the tables attached to his great works. What lifted Kepler above his contemporaries was that he was perhaps the greatest mathematician of his era. He brought to his analysis of the motion of the planets a level of mathematical knowledge that far exceeded that of his immediate predecessors, Tycho Brahe and Copernicus . From his various publications it appears he went through a difficult and prolonged struggle to discard Plato's influence and develop his laws of planetary motion.
It was compassionate of you to say “generating high quality data” is what Tycho Brahe is famous for
Q: When a planet moves a around a star, with different velocities at it’s perihelion and it’s aphelion,
does that mean that time on that planet goes slower or faster,
because time goes slower when an object moves faster?
I love watching videos like this, we need more educational documentaries like this because we certainly can't rely on our piss poor education system to do the job right.
in modern terms, the models of the Solar System proposed by Copernicus and by Tycho Brahe were the same, their difference only depends on where you place your frame of reference (the Sun or the Earth).
Have you visited the remains of Tycho's observatory? They have turned a church into a museum with his instruments recreated. There is also some good Whiskey and pizza on the island :-)
Let me know when you plan to visit and I'll organize another visit with the astronomy club I'm on the board of! :-)
so what's the other focus?
Tycho was also famous for being a rich eccentric who loved wild parties. During one such party, he refused to relieve himself because he doesn't want to stop drinking. He died of a bladder complication several days later. Kepler, as his apprentice, got his hands on those meticulously kept notes before they can be given to Tycho's heir and the rest is history.
If the outdated primary educators (not the teacher, I meant the old dudes making the decisions up top) can make knowledge as fun as youtube, we'd have a far brighter population.
+SQW0 We love these stories - thanks for sharing! And thanks for watching!
That's crazy...everything I hold it in my bladder just says "aww fuck it"
The Earth's Axial spin and our Moon's orbital direction aught be synchronized with the Ecliptic plane's overall motion.
The sum of the distance between each endpoint or focus and any point on the ellipse is constant
