Understanding Instantaneous and Average Velocity using a Graph

[@adrianaselena14]

Thank you IMMENSELY for providing these videos for free. You are a god at what you do.

[@FlippingPhysics]

You are welcome. I enjoy your hyperbole.

[@tzeshawnlee6562]

Short, precise, a good video for pre-IB physics newbies like me.

[@FlippingPhysics]

Glad to help!

[@studiomath1]

Thank you so much for this! I love that you made it fun! As a tutor, I am working on understanding calculus better to upgrade my tutoring skill set. You made my day helping me understand this at a very core level!

[@FlippingPhysics]

Glad it was helpful! If you are looking for calculus specifically, checkout this webpage of mine. Many of the videos labelled "APC" use calculus. www.flippingphysics.com/ap-physics-c.html

The third guy is literally me hearing all this 💀

[@RaffaelloLorenzusSayde]

What if I have a data chart of the points needed to graph a velocity to time graph and one of the points is at time = 0 and velocity final = undefined? How would I graph that?

[@ngobeninben9841]

The best presentation I've ever crossed paths with online.😊😊👍👍👍👍

[@FlippingPhysics]

Wow, thank you!

[@Jrosado8]

Lmao! This video is so funny! I was recently searching for a video on Physics and stumbled upon this one. You are a creative genius. I know this took some technical skill and trickery to create this video but you pulled it off very well. I was laughing the whole time while watching this video as well as learning the material. Thanks for your informative and very entertaining help. Keep up the great work!

[@FlippingPhysics]

+Jrosado8 Thanks! You have summed up my goal as a KZbin educator quite well.

[@rchlboyd]

This was a great help. Informative and entertaining!

[@SD-kp6fj]

Thank you so much I'm studying for the MCAT and physics is my most feared subject, thank you for making it less scary :)

[@saraqueen4227]

this video is awesome...........books are irritating me when i try to understand this,...............but your video awaken me from the sleep, so thanx a lot.......keep doing this like videos.......for students

[@FlippingPhysics]

You are welcome. I will do my best to continue to make these videos. It makes me happy to know they are helping you learn!

[@saraqueen4227]

bob i had a doubt in this video,book said the formula of velocity is v=displacement / time.........but in this video student bob telling velocity = change in displacement / change in time.........but book says that is formula of average velocity......so i am get confused lil bit........is it both are same?.........

[@FlippingPhysics]

Sara, my queen, I will do my best to answer your question very carefully, however, understand a KZbin comment is not a great place to try to deal with these questions. Which is why I have all the videos. 1) velocity equals change in position over change in time and velocity equals displacement over change in time. Displacement and change in position are the same thing. Notice: velocity does _not_ equal change in displacement over change in time. There is no such thing as change in displacement. 2) All of the velocities in (1) are average velocities. In an algebra based physics class like the one this is for, there is no equation for instantaneous velocity. (In calculus instantaneous velocity is the derivative of position with respect to time, however, you need calculus to understand that.) Therefore, instantaneous velocity is the slope of the position as a function of time graph at a specific time. I hope that helps!

[@saraqueen4227]

awesome sir,...............now i understand.........you are a such a great teacher...............but unfortunately i dont have a good teacher like u in school..........but i had lots if doubt......as u said youtube comment is not good for these questions,......so is there any other ways for me ask my doubts....?

[@BoZhaoengineering]

Analysis rises. Without it, we don't understand what's going on inside.

[@kwakunyarko6371]

If at any point the regular (blue graph) had a line parallel to its total average velocity(red graph), then the average and instantaneous velocities would be the same, right?

[@FlippingPhysics]

Yes. Because the slope of a position vs. time graph is velocity, parallel lines would then have the same velocity value.

[@LolaFansOnly]

keep up the great content!

[@mitchellfrench5742]

This was a great help man

[@mmaani9988]

best video ever, thanks you man!!

[@amirashoury783]

great great video!!! i totally got it you are the best!

[@FlippingPhysics]

Thanks. Glad you totally get it now!

[@deependraverma4382]

When Billy and Bo said INSTANTANEOUS and AVERAGE I laughed a lot, But anyway this video helped me way more. Keep up that good work.

[@FlippingPhysics]

Thanks. I will keep doing my best.

[@alifayyaz9950]

Thank you so much this helped a lot.❤

[@FlippingPhysics]

Glad it helped!

[@MsDJ619]

haha this makes studying more fun

[@tanish9381]

best physics channel!!!!!!!!

[@FlippingPhysics]

Thanks!

[@MegaLazerman1]

Is it the same for instantaneous Acceleration

[@FlippingPhysics]

This is an interestingly difficult comment to reply to, mostly because the comment itself is so nebulous. What is the "it" you are referring to? There are a lot of things that I talk about in the video but mostly "it" is the relationship between instantaneous velocity and average velocity, so perhaps what you mean is "Could this video be titled 'Understanding Instantaneous and Average Acceleration using a Graph?'". If this is your questions, then, i believe the answer is Yes. I am simply using Velocity as a way to discuss the differences between Instantaneous and Average and I can't think of any differences that would occur if you use Acceleration as your example instead of Velocity.
