Physics 18 Gravity (15 of 20) What is Geosynchronous Orbit?

[@runescapegodsword]

awesome!!!!!!! On behalf of everyone, i would like to thank you for taking the time out of your day to help us!

[@MichelvanBiezen]

Roberto. Thank you for this positive feedback. I started making videos a year ago and because of comments like yours I am planning on adding many more in the future.

[@runescapegodsword]

keep helping more and more students take that first step into string theory, Eulers equation, and relativity

[@frankdimeglio8216]

@@MichelvanBiezen A great breakthrough in physics. The gravity of WHAT IS THE EARTH/ground is BALANCED WITH and by WHAT IS E=MC2 (AND TIME). Indeed, TIME is NECESSARILY possible/potential AND actual ON/IN BALANCE. Great. What is E=MC2 is taken directly from F=ma. Accordingly, ON BALANCE, the rotation of WHAT IS THE MOON matches the revolution. The stars AND PLANETS are POINTS in the night sky ON BALANCE. c squared CLEARLY and necessarily represents a dimension of SPACE ON BALANCE. Consider TIME AND time dilation ON BALANCE. Now, carefully consider WHAT IS THE EYE; AND consider what the TRANSLUCENT AND BLUE sky ON BALANCE. ELECTROMAGNETISM/energy is CLEARLY AND NECESSARILY proven to be gravity (ON/IN BALANCE). Magnificent. WHAT IS E=MC2 is taken directly from F=ma. Consider what is the fully illuminated (AND setting/WHITE) MOON ON BALANCE. c squared CLEARLY represents a dimension of SPACE ON BALANCE, AS WHAT IS E=MC2 is taken directly from F=ma !!! The stars AND PLANETS are POINTS in the night sky ON BALANCE. Absolutely magnificent !!! It is mathematically proven. By Frank Martin DiMeglio

the sound of marker hitting the board is satisfying to me for some reason :,) great videos!!!!

[@healthiefreake1455]

Thank you so, so, so, so, SOOOOO much for your wonderful videos! They help so incredibly much and I'm so grateful that you took the time out of your day to help students like me :)

You can also calculate geosynchronous orbit using Keplerian physics. P^2 = K A^3. K = 1/Me -> P^2=A^3

[@MichelvanBiezen]

Yes. We have videos on that in the astrophysics playlist on that channel.

[@bekalutadesse8948]

Why the orbital velocity doesn't equal to zero. B/c they are in a circle. So they back where they started?

[@MichelvanBiezen]

If we were considering displacement, you would be correct at the moment, and each time, when the satellite reaches its original starting point. But that is not the case with velocity.

[@bekalutadesse8948]

@@MichelvanBiezen i didn't get you.

[@MichelvanBiezen]

The orbital is continually changing (not the magnitude, but the direction). At no time will the velocity be zero. In a circular orbit, the magnitude part of the velocity will be constant, but never zero. The direction of the velocity will continually change.

@@MichelvanBiezen thankyou .

[@nicholasurlacher4267]

Thank you so much for your incredibly helpful videos. I stumbled across your channel while searching for videos that show how to calculate "Satellite Mean Orbital Radius". I'm attempting to teach myself Johannes Kepler's Third Law of Planetary Motion, as well as the above mentioned Satellite Mean Orbital Radius and Planet Mass. I decided to start with Kepler in order to understand why our moon doesn't fall into the earth. I understand from Einstein's General Relativity that objects with significant mass bend the space-time fabric around them. Where I seem to be having amateurish trouble is understanding what keeps the moon from crashing into us. So here I am seeking to understand Kepler"s Third Law in the hope that with a better understanding of orbits I can better understand our planet-moon orbit.

Nicholas Urlacher You may also want to look at the playlist: PHYSICS 6 NEWTON'S LAWS AND ROTATION and the playlist ASTRONOMY 3 MOTION OF THE MOON

[@alitn588]

very informative. thanks

[@anzatzi]

I see the math here but I can't get the concept. Isn't there a geosynchronous orbit at h=0? and of course. h==22, 246 mi? couldn't there be others in between?

[@MichelvanBiezen]

There is only one place where you can have a geosynchronous orbit.

[@anzatzi]

@@MichelvanBiezen Thanks--got this when I realized a person standing on earth has a tangental velocity far less than a satellite in an h=0 orbit. Great series!

[@omaradel210]

Good man 👍

[@MichelvanBiezen]

Thanks ✌ Glad you liked it.

[@nickmanning3555]

Why don't the satellites follow elliptical orbits such as planets around the sun? Is it because the two objects orbit the center of mass which is basically the center of the earth in the sattelite-earth system but not the center of the sun in the sun-planet system?

[@MichelvanBiezen]

Nick Satellites are moved into the orbit desired by the aeronautical engineers.

[@aamirazam5229]

But how is that possible? I mean they cant alter Earth's gravitational force can they?

[@pipertripp]

no, but by using thrust they can circularize their orbits (see Hohmann transfer orbit on wikipedia). During the application of the thrust, Kepler's laws are not valid, but as soon as the thrust stops, his laws are applicable again.

[@Qman509]

Why would you use 86,164 seconds instead 86,400 seconds relative to 1 day?

[@MichelvanBiezen]

One rotation of the Earth takes 86,164 sec (about 4 minutes less than 24 hours). (That is a sidereal day - one rotation relative to the stars)

[@ItzzBrandonn]

Where does the number come from?

[@joshuaoriendo7781]

I love Gravity and Magnetic Fields xD Thumps up (Y) (Y) :D

[@CaptainCalculus]

That's also why spy satellites tend to be at that height...

[@ptyptypty3]

velocity of that satellite is roughly 6,789 mph ... YIKES!!

[@MichelvanBiezen]

Yes, they move very fast!

[@ptyptypty3]

just curious, but how does a satellite orbit a Flat Earth ?? (you KNOW I'm kidding!! lol ) :) Hello Michel and Wife...

[@MichelvanBiezen]

Hi Philip. You would be amazed. I once met an airline pilot who believed the world was flat.......

[@MichelvanBiezen]

Philip, if Earth was flattened like a plate then the satellite would go around the outer edge of plate. ;) - Wife
