Thank you -- I love science but am weakest in physics. You make it painless to learn! I look forward to the other lessons ahead.

I was scrolling through ALvid and I saw this and I’m like ooh I could learn something whereas my classes for school hurt my head so this will give me a break from school but keep me learning also since my physics teacher didn’t really have the degree to teach science he was better at math than science. We had multiple substitutes that made more sense then the actual teacher so you teaching this is awesome. also on your way to get your teaching license happy for you. You should do great.

I've been telling everyone about you but am atheist so been good to be like science class for the kids but hmm she don't think the same is the feeling I get though I know it's helped people so what can I do to get people to listen other then be a good example by wearing gloves masks using everything I can to get by an make it better and safer if people don't wanna listen per say to science it drives me up a wall but I stay positive an tell the facts as I know them ha ty again for great class!!!

Why did the heavier balloon fall faster?? Doesn't everything fall at the same speed because of inertia and gravity??

I think I heard him say that "oil is heavier than water, pour oil in water and it sinks to the bottom" If he said that I would no longer have an interest in his class!

that is why when you put a vid on slow-mo, the voices are low pitch because the fps is less frequent.

Sound doesn’t travel through air like waves travel through water. Sound waves are longitudinal waves while water waves are transverse. Im sure Mark knows that, it’s just diving deeper into something off topic and that takes up more time lol. But my nerdy self had to point that out.😅 Edit: yup he knows

Mark please come teach at my school oh my god. We have like 3 physics teachers, all of whom I’ve heard a lot of complaints about. One does AP and honors and I failed out of her class because I never understood material when she taught it, the other two I don’t know personally, but many of my friends complain about the work and not understanding, and honestly I think most of us hate physics.

I’m watch videos on youtube 1,75 faster than normal and it’s fascinating how I can explain why the sound is more acute than at normal speed with what you explained.
