At 1:30 she should say the force is inversely proportional to the square of the distance (as opposed to proportional to the square of the distance).

I'm confused too. This teacher does not explain as well as the other ones.

A perfect lecture. Thanks and congratulation

3:15 Is changing of coordinate system is a necessary step for a solution? It feels like discombobulative cheating.

In this video following question has been addressed regarding spin based UFT I’m working on.

1. Difference between Atom structure and planetary system in terms of Ashton distribution system
2. Why Ashton concentration increases near a body
3. How spin of one object influencing spin of objects around it due to spinning Ashton field
4. Why few planets and natural satellites in solar system spin in clockwise direction while most of them in anti-clockwise direction
5. How planets came into existence in solar system
6. What is the relation between Ashton and photon and size differences
7. What is the speed of Ashton and photon and how it is almost constant
8. Why bigger atom decay higher energy at any given temperature
9. Why high frequency light collide better than low energy light
10. Why Ashton do not collide with each other almost in free space
11. How celestial body came into existence
12. Why orbits are elliptical for planetary system
13. How planets and natural satellites are evolving
14. Why black hole doesn’t emit light
15. What is dead star
16. How mass of a celestial object can be calculated mathematically
17. Why some celestial objects have melted zone below surface of the body
18. To burn what is required for a star
19. Why Jupiter doesn’t burn
20. Why each planet have its own periodic table

how did they even computed that proportionality constant?

[tuha]

aha, maybe this is one of the origin of "I just stand on the shoulder of giant peoples."

[mrhoneybadger]

how do all the profesors write inverted and backwards?

[sir_aken]

I'm a little confused. Why did r (hat) unit vector have to attach to the Universal Gravitation equation?

[rahmanelangoli]

Feel like the teacher itself is confused...
