Discovery of Electrostatics | Discoveries and Projects | Physics | Khan Academy
Our ancestors noticed that when amber was rubbed against fur it attracted small objects...why is this? Created by Brit Cruise.

Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry.
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.
For free. For everyone. Forever. #YouCanLearnAnything

This is so heartwarming to see how Sal took this guy on and helped him out ❤
Kind of cool....For a small kid in school....I was hoping for something better, but then the hot glue gun was out and it went a little downhill from there on.
so many wrong technical aspects but it's cool to see the inside.
fascinating teardown
More reverse engineering videos
The Voltage that comes from the wall is actually 240 Volts and wall plugs have 3 Pins NOT 2
DVD Players actually use 240 Volts
It's too bad you smack your lips so much.
Thanks, very detailed explanation
Excellent educational video. Thank you for explaining each component in detail. I learned a lot.
Nice! Thanks!!
awe the cat
The air is first radiated and then (force) convected away (with the fan), right?
It doesn't work and it's painful. Should the distance between the two magnets be equal to their distance from the center? Also, how many volts do you use in the battery?
If i cut the wires going to the heater, would the motor be affected or would it just blow cold air? Or would I have to forcefully bend the bimetallic strip in order to get cold air?
Hello,would you like to diy et dryer?please.
Thank you for giving detailed information. Very easy to understand.
ok ok ok ok ok ok ok ok ok ok ok ok
No voice 😢😢
More reverse engineering videos please
Brilliant, thanks! Seeing the cut-open motor was especially helpful for me to understand.
More reverse engineering videos on CZcams please.
my hair dryer broke, so i decided to take it apart and watch this
Hi would you mind listing the materials you used?
why is a video 10 years ago so good quality
Send me video on wassup
Please make a "What is inside a paper sheet music box" video someday. That would be interesting.

Woah this is awesome
To all the fellow BJU students. The small letters on the bottom are ETL and NOM since they're nearly impossible to see. Congrats on almost graduating btw. <3
The🤫 secret🤫 of how to turn CD to solar panel czcams.com/video/hx9SzPIQG1w/video.html
Can you please explain how it works?
picture = 1000 words. Experiment = 1000 pictures.
Thanks
yuguug
Am making mine thanx...i would like to book online class ..
Would you mind posting the list of materials here? Thanks in advance.
Thank you for this video
"So that you can see all the different parts of the motor" and in the end, you cant see shit. Geez, the level of stupidity in that logic instead of just peel the tips on the cover to take the motor out...
Volume needs normalization. Also why are you calling it "sodder" there's an l not two ds?
Americans pronounce it as 'sodder' and not solder for some reason lol. Not sure why though :)
@@jonateez is correct, this is how we pronounce it. The "l" is silent here
i love a motor
Material list??
Very good video thank you so much also i will try this you got a new sub
Wow I remember my young self watching this amazing video
Bhaiya hamare ko motor chahie
Thank you! I was testing a SPDT switch with 2 _input_ sources, when these switches are actually for 2 _output_ sources!
some of my computer optical drives on read cd's now and some of the will only read dvd's now.. is there any way to fix these.. they are supposed to read both..
Well explained
