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.

[@omshetkar06]

great dude with great explanations and great line drawing skills. 10/10 tutor vid

[@GabbyGrapes_]

"it may sound like mathematical witchcraft"

[@billelguechi5831]

U deserve 5 stars 🌟🌟🌟🌟🌟 for this awesome explanation

[@M_Muneeb-0]

For the people wondering about Period, the actual word for it is "Time Period", hence represented by "T"

[@TomazSuller]

I'm pretty sure no one is going to read this at this pount. Whatever.
I belive 'T' is used to represent period because 1) Period in latin is 'tempus' 2) 't' is already used to talk about an interval of time.

[@blissfulfragrance2511]

Tomáz Suller or maybe coz period may be short for time period?

[@valentinmi66]

good stuff dude thx

[@abhitruechamp]

No one you say?

[@v.radhika6927]

0:12 "Mathematical witchcraft 😈" .
🤣🤣🤣🤣🤣 That's true sir.

[@rushilpatel7418]

David's Mathematical Witchcraft= Sal's Fancy notation

[@hiteshmeena1749]

Thanks alot sir...🙂

[@nancychuttani5831]

Great explanation 😊💕

[@ed684]

Thanks a lot

[@justridemtbofficial9483]

Thank you so much

[@mathycatty2694]

I think time is on the horizontal axis because it is much easier to make something as a function of time. And about the "horizontal=vertical" business, the position is kinda just net displacement.

[@debuginfo]

Oh, a period, eh?
Repeat a whole cycle,eh?
😂 this is why khan academy is my fav

[@joshiifruit5554]

thanks bro

[@nikolanovakovic4150]

thank you

What's meaning of "

[@abhitruechamp]

4:04 except when its Einstein's theory. THEN, we decide, maybe its ok.

[@jacobmeierhofer9080]

Just a by the way, you can faintly hear the friction of the mouse moving when you make big movements. Slightly annoying could be an easy fix(or not), just wanted to let you know, great videos keep it up!

[@mohitkumar.24x7]

👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍😃

[@appupyati9846]

I want one solution : a body is oscillating along astraight line with frequency 1/2Hz if its amplitude is 10 cm find out distance travelled by body in 5/4s?

[@meltdown6856]

Appu Pyati
Freq=1/2
So, T=1/f= 2s
Amplitude =10cm
Assuming it is SHM , total distance travelled in time period =4*10=40cm
Therefore distance travelled in 1 sec= total distance / total time =20cm
Do distance in 5/4 sec= (5/4)*20
=25cm
Pls correct if wrong

[@kaamilmirza6963]

R.I.P. for who preparing for JEE

[@saniasultana7141]

🤨

[@debuginfo]

Why?
