Lecture on Torque 1/3

[@ramahadaki9432]

I'm a really big fan of your learning glass and your explanation, thank you!

[@gebyvargas6057]

Your lectures are very helpful for AP Physics 1 as well! We have a new teacher that is also new to the course so I use this videos regularly to help with my homework, thank you so much.

Wonderful to hear. It's definitely one of my goals to help with AP Physics, so I'm always interested in more feedback. Feel free to give me ideas. Cheers, Dr. A

Amazing videos as always!!!

[@Aditi_1319]

prof. u are amazing.......

[@hereiswherethereisnt]

cool setup

[@890slay]

Are you using a mirror reflection for this video? This is turning a quiz, but we'd like to know... Good presentation, by the way.

[@yoprofmatt]

+890slay Yes, we're using a mirror. Literally. Although of course you can do it in software as well. See this video: kzbin.info/www/bejne/eYirfqeJg7Crj6M Cheers, Dr. A

are you really writing backwards? man im confused

[@ilansviry4158]

More likely: They flipped the video to the side so when he writes normally and they flip it it looks normal to us. you can notice that he is using his laft hand.

[@abdurrehman8323]

i agree with him

[@likeaspinningplates2138]

wait why is the torque of the person who is trying to get in the classroom rF/2?

[@AndrewDzula]

If the length of the door is 'r', since he is pushing the door at the very middle, 'r' becomes '(r/2)', the torque is now '(r/2)Fsin(90degrees)'

[@harshitkumar1144]

why r u so slow.is that because u use left hand

[@yoprofmatt]

No. Probably just in need of coffee. Cheers, Dr. A
