I got two questions which the video about orbital motion leaves unanswered. 1. From the main drawing at 15:00 I conclude there could be many different velocities to allow staying on an orbit. I conclude the velocities should be in a range. Does the equation from 30:25 mean the minimal velocity to get into orbit? How to calculate the maximum velocity then? 2. Does it mean the moon or spacecraft will be orbiting forever when we ensure the orbital velocity? The moon is moving away from the Earth and the satellites are equipped with various systems to maintain their designated orbits. So aren't there problems with maintaining the orbits?
Omg reminding you again we watched your videos alot when my daughter was 7th grade homeschool 🥰🥰🥰now she is a Junior in high school taking Chemistry she's gonna love this
I am totally confused on how people like Avogadro, woke up one morning and created the "Avogadro number". Like it was "Aha, yes its exactly 6.022x...", how in the world did you at that time even know this was THE number.
Best learning channel on UA-cam
Thanks so much, I really appreciate that!
I wish that I had you as a teacher when I was young.
Coming across your channel is the best thing that has ever happened to me academically❤
thank for another great video

Thank You 🌱🌿🌿For Sharing
So how many dozen is a mole?
Divide 6.02 to 23 power by 12
@terry123 that is the wrong answer. The correct answer is 6.02/12 times 10 to the power of 23
awesome thanks for your help
Nice 👍

@6:00 Should be 602 Sextillion if I count correctly in my head.

As much I appreicate this channel, I prefer on this one the explaination at Steve Mould's channel. It's less chaotic.
Gotcha this is good
I donot have chicken, I do have 4 eggs.
According to what I have read and seen, a mole is such a mouse that dwels underground or a snitch

Ridiculously superfluous.
It's designed for all candidates of all ages, like 14 years old, and for them to fully understand the logic.
