Han Solo teaches physics? amazing.

AnonymousAsh, Some of my other videos I'm more like Chewbacca. Thanks for the comment, and keep up with the physics! You might also like my new website: www.universityphysics.education Cheers, Dr. A

You're the best teacher ever sir , I really wish I could sit in your live class once . Just cannot tell you how much your videos have helped me during online classes . Love from India 🙏

[@sea5205]

Your videos are amazing thanks

[@mojankhosravi4518]

wow!! what an explanation... thanks a lot, I love your videos

[@syedwalihaider6497]

I love you and your helping tools sir I salute you

Dear Professor. I understand the calculation and the "weightless experience" as an ideal case, where no air resistance ist present. Should in the reality happen, the elevator will experience a strong resistance and will fall with an acceleration less then g. The person in the elevator does not experience the air resistance, but it is still attracted by the earth and will fall with an acceleration equal to g. So the person would feel compress to the floor. Is my idea right? Best wishes!

At 8:20 he says there is no gravity at the center of the earth. I don't think that is quite right. There is plenty of gravity at the center of the earth, but it is pulling in all directions equally, so the NET effect of the gravitational force is zero.

[@alexjohnward]

Gravity in terms of a net force. Interestingly there is still some Gravity, pulling towards the Sun!

GREAT PHYSICS LECTURES !!! :))

[@sanjeevsrivastava3389]

I love u sir seriously!!!! ❤️

[@mr.s4a4ge58]

Hey 2 things i noticed. First of all g is essentially not 0 , given tht acceleration due to g does decrease with depth by a factor g(1-d/R) , but wht happens is tht the g due to both the hemispheres of the earth cancels each other. Also the hollow tunnel through the centre of the Earth wud put any object in a simple harmonic motion , with gravity as the restoring force and time period T=2pi root( R/g)

[@attitudekingsriraajmagic4639]

Respect ur lecture...sir...wonderful

If there was a hole dug all the way through Earth, would the two pieces stay close to one another or would they separate?

[@mumtajkaly1410]

How is he writing backwards?

[@csanilkumar5415]

GM ÷ 1^2 is greater than GM ÷ 6371000^2 , therefore we jumped in to the hole( tunnel) we stayed in the centre. The gravity at the centre is not zero Because GM ÷ (0.00000001)^2 ≠zero.

Thanks sir for ua videos which are very useful for me ....❤

[@imjoker3874]

Hi professor I don't understand why the normal force is considered as your apparent weight; you mention we feel heavier when accelerating upwards but I thought we will feel heavier if gravity is larger than the normal force

[@yoprofmatt]

imJOKER, Imagine you're falling with nothing underneath you. Certainly there is gravity, but what can you say about your weight? Thanks for the comment, and keep up with the physics! You might also like my new website: www.universityphysics.education Cheers, Dr. A

[@syedwalihaider6497]

sir have you uploaded any videos regarding stationary waves and light

[@SteveWideawake]

how come when a plane travelling 500 mph hit air pockets and fall the people get stuck to the roof but the ISS is falling 17000 mph and they float? If the gravity is strong enough to hold the ISS in orbit why no gravity inside the ISS?

[@marionicola2447]

ISS is in orbit, the plane is not . The Sun's gravitational field is strong enough to hold the Earth in place but we don't all fall towards the sun do we
