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 is a nonprofit with a mission to provide a free, world-class education for anyone, anywhere. We believe learners of all ages should have unlimited access to free educational content they can master at their own pace. We use intelligent software, deep data analytics and intuitive user interfaces to help students and teachers around the world. Our resources cover preschool through early college education, including math, biology, chemistry, physics, economics, finance, history, grammar and more. We offer free personalized SAT test prep in partnership with the test developer, the College Board. Khan Academy has been translated into dozens of languages, and 100 million people use our platform worldwide every year.

i think "s" is used instead of "d" because "d" is used for distance in calculating average speed
S means strada or rode in latin
I have a HiSET exam on Science so, I am learning about Physics among with Biology and Earth Science! @Khan Academy
thanks from Egypt
4:24 for those new to Δt notation: Δ (Delta) is a greek capital letter. Δ comes from the word Διαφορά which translates to Difference. So, either Δt or dt is about the difference between 2 "points", like, starting and end point of your measurement. I believe that Δ is close enough to D and since the word means the same and also starts from the "same" letter in both languages maybe it's easy to remember and might be a good way of thinking it as you try to memorize stuff.
Are these video enough to prepare for GAMSAT Physics?
this vid is lit bruh
Very well explained! 😊
1:27 "I care about the SIZE of this thing" 😏
The videos would have been better with PowerPoint pictures instead of drawing and repeating yourself
Thank you so much this was so helpful 😭
A bike starts from rest and accelerates at 3.5 m/s for 9.5 s. What is the velocity after that time?
I assumed that s stands for "sum" of the forces, which will give you the ultimate magnitude and direction, i.e. the displacement.
In miles that is 1 mile per hour roughly
i like chocolate too
Does anyone still here in 2022?
You don't really have to take the long way , your teaching skills need more skill. You explained the same thing for half the video.
I think s is for "space", as in travelled space
did he pay attention to sig figs? he never mentioned them so Im just curious
Is it the same with kg?
mans a life savor
boring
I feel like this guy can solve world hunger
Great video. Thanks !

You duck bro
s is latin for another word that means space
comment
If someone as dumb as me can learn from this, anyone can
is an app or a website like calculating in your screen, what is the app, please could you tell me.

👍👍👍👍👍👍👍
HAIII
What, I heard USA is the only country where dont use km as a unit 🙁
I was pleasantly surprised at how he pronounced Shantanu. Sounded quite Indian. He could've been like, "Shaan-Taa-Nu," but it felt really normal. By the way we say it here, ofc.
