How to Remember/Derive the Kinematics Equations

An explanation of the kinematics equations that can be applied to AP Physics and other physics courses.

Girl im literally in university and you are the only person after all these years who has been able to get me to understand this THANK YOU

Reverse engineering these equations seems like a very good way to teach them. Thank you

I often see a 5th to save some derivation, and the 3rd rearranged to match. I think it's more intuitive to a graph with constant slope, which is basically a triangle on top of a rectangle. That also gives you one equation already missing one of each of 5 variables.
∆x = Vf•t - ½at.
∆x = V0•t + ½at.

One thing I am having trouble with is why are we jumping back and forth to get the equations? Like, how would I know to pick equation number one and two for three or whatever, why not just use one, or just 2? I just hate physics

thank youuuu so muchhh really helped out alot!

I really appreciate this video, thanks alot

Omg u hold the pencil the same way as me

Bruh if you’re going to write something in vector notation then write it all in the same notation, I hate seeing a v hanging around when it equals the sum of 2 vectors -_-
Yes I’m a mathematician judge me 😂

Great video. If I had to be super critical, I would work on the voice (it sounds really nasally or raspy) and not as clear as it could be. This may be due to the mic quality, or you're way too close to the mic?[to be even more critical, your intonation rises a lot as you speak - books say you want to lower the intonation as you end a sentence, not the opposite.] In addition, you should use a pen instead of a pencil if you want to make the writing stand out. I had to look harder to see the information. Better lighting focused on the paper could've helped as well. In addition, the clipboard hanging in the air as you wrote added to the "awkwardness" of the video, as the information was moving and shifting rather than sitting stable and easily for the viewer to see.
Thanks for the video!
EDIT: forgot something
