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

Houston, we’ve got a Parabolam

[@user-li8cc9nk1h]

wow, explain all of this in 13 minutes somehow I understand the topic.
My teacher here talking for a whole 45 minutes and I was like WTF are you saying

[@natelarmand2399]

Mo money, mo parabolems 9:33

[@I-used-to-be-orcaz]

we have parabolems

[@samweiss6088]

Is there a review sheet like the one for the 1D motion?

[@justasydefix6251]

very refreshing

[@masonbirch6319]

Gods work

[@saviour_3.1415]

Newtons work

Why is physics so confusing

[@TheKiyoshiRyu]

Hey guys, I had a question. Let's say that the left is the negative direction and an object were to be going to the left at a constant 5m/s. Would the object's velocity be -5m/s to the left or would it just be 5m/s to the left?

[@prachisharma8076]

The velocity would be -5m/s since velocity is a vector quantity and it has both MAGNITUDE '5' and DIRECTION 'negative'. However, if you consider speed which is a scalar quantity it would only be 5m/s.

[@abdullahamir119]

If you are already mentioning that the direction is to the left then the velocity will be only 5ms-¹ to the left. You will only take it -5ms-¹ if the direction is to the right because in that case the direction of velocity would be opposite to the direction considered (i.e the left is opposite to the right).
The negative sign is only used to indicate opposite direction to the direction considered

[@nyakallotoons4450]

Can you please make a video on circular motion at constant speed

[@majusigoey4743]

~Inshallah~
Many thanks, akhi

[@davidnemewe9192]

slow the speed to 0.75x

[@eliseonator]

lmao i sped up to 1.75 xD
