Learn what instantaneous velocity is, why it is important, and how to calculate it in physics. We begin by discussing average velocity, and demonstrate that the instantaneous velocity at any point in time is the slope of the line tangent to the position-time graph at that point.
Specifically, we take the slope of this line as the limit when the change in time approaches zero. This is explained to be the basic definition of the derivative in calculus 1. Because of this, instantaneous velocity is used heavily in physics, mechanics, and calculus.

watch this video examination in life never give up-th-cam.com/video/k4w4pak66V0/w-d-xo.html
this was literally the best explanation my all confusions got cleared through ur video❤
This is the best explanation I have ever seen on YT.
Shahidul Islam yes 100%. I watched 3 others before this and my professor isn’t really lecturing well due to everything being online, AND I FINALLY UNDERSTAND. Grateful for this guy and the internet.

Seriously 🥰
Taking Calculus 1 now and your video seriously helped not only made limits, velocity, and tangent line points make more sense but made it very relatable!! Thank you so, so much!
Awesome! Thank you so much!
Thank you so so much!! Wish we had more teachers like you!
I 💘the way this man explains math problems...He is the only instructor that I have found, in ALL of my years of highschool and college, that takes the time to mythodically brake down problems and equations, piece by piece. None of my college and high school teachers ever did this. We were just given a very complex formula and variable or term equivalencies to plug into the formula, but never really explained how the input/plug in values worked out in the formula. See, you can be given a formula in an arrangement that you may not be familiar with...Example: most people know that nx^n-1 is an exponent formula rule in Calculus...However, if you never knew what the superscript/exponent portion n-1 of the formula meant that you were subtracting 1 from the n exponent, than how would you know how to solve the problem if given a value to plug in for n? That is the beauty of how he explains what the individual parts of a formula or equation means and how to use when given input values to plug into the formula. It's all in the way the variable pieces are arranged in a formula and how familiar you are with knowing what the arrangement is telling you to do.
My exam is tmrw and this explanation made it so much easier for me to understand these concepts
thanks man keep up the good work :)
THANK YOU, U REALLY HELPED ME
THANKS
33:27 me when I spent the whole night studying Math and still failed
32:51 My teachers discussing how to give me grades
Please you guys are so funny😭
This is an amazing lecture. Thank you so much for great explaination. :)
This is the best physics channel!
This guy knows to teach Physics! Well done. Very clear and concise explanations
Thank you, this is the best tutorial I ever watched for mathematics problem
You explain from the origin and I like this type of explanation. Anyone can able to learn from you. Thanks a lot for your efforts :-)💚
Amazing explanation. Would love to see a real problem being solved by you❤️
Thank you for reviving my physics interest.😌🙏🏾
Thank you so much! This made the concept so much easier for me to grasp. I think the graphs, seeing ▲x/▲t graphically really made the average and instantaneous velocity click for me and it made the relationship between tangent lines and secant lines also really easy to grasp. Much appreciated!
This professor is a stud in teaching any math subjects; I took calculus in college , passed with a C with no idea of the concept.
Sir the way you explain things is so clear and effective. 100%.
So happy you liked it!

@@MathAndScience Hello Jason, I am a student from Papua New Guinea currently doing my undergraduate program in Petroleum Engineering in China and would like to inform you that your videos on Math and Physics helped me a lot, especially Electrical & Electronics. Thank you so much. I really appreciate it.
steven spikip you are very welcome! You go!
Wow! This is more likely the definition of a limit!!! I was amazed! Thanks Sir Gibson.
Thank you so much for this. Y 've really help me alot
I LOVE THIS GUY!!!!!!
Thank you so much! Taking Calc 1 and this is an amazing explanation.
thank you for very well explaination ..
This was the video I was searching for. Helped a lot. 1+subscriber
THANK YOU... SIR...!!!
I understand well what you are teaching... Great method...!!!
! you really makes me love physics! love yaaa
I can just say thank you .you are very nice teacher👌👌👌
Thanks, first time enjoying physics
Amazing, thank you sir! 👍🏻
Thank you very much sir for your explanation.
Now you have a fan from India thank you so much!!!!😀😀
Slope is everywhere! Physics, econ, even sociology

You really helped me
Best explanation am clear now, thank u sir❤
Thank you, this was really helpful
You are excellent sir
Sir you are the best
Best explanation ever 👍👍👍
Viewers:
If you're thorough with average velocity and need no explanations on the same, if all you've come for is instantaneous velocity, jump to 14:20 :)
thank you!
Your videos really helped me
Keep going..❤🙏😻
Good afternoon Professor. Thank you very kindly
Amazing video man..
Ok After this video we should get real a exam problems and see how you solve them.. in a separated video or at the end of this video..
Amazing explanation. Thank you.
Welcome master just keep it coming
So happy you liked it!

Thank you, very helpful!
thank you thank you thank you!
thx u so much - ❤️
Thank you Sir 🌿
U r excellent sir
Well explained
his board game is lit
My dear Sir you are great teacher you have cleared my concept about instantaneous velocity.l am from Pakistan
Awesome! Thank you!
THANK YOU SOO MUCH .
Thank you so much❤❤
where is part 2???? everything is great, the explanation and everything was amazing but i still need part 2 if there is any!!!
Best explanation
33:23 i like this part..ha3...in physics, what we think aren't important or necessary in terms of explanation turn out to be somehow actually effective in helping someone understand that specific thing...
You are the goat!
Fantastic, thank you 🙏
Great video, really helped, just wondering how precise is this method as we don't ever get an exact answer, because we can never divide by zero?
thank you very well explained in details
What do you mean 'velocity right now'? Velocity can be measured only during some period of time. At an instant distance is not changing. Is it something that is created to ease calculation, but does not exist in reality?
Great work dude keep it up
Thanks
much thanks sir
The closer the distance is, the more accurate the Instantaneous Velocity is.
Thanks for helping its amazing !👌👍
Thank you so much!

Thank you so much for the simple yet effective explanation
THANK YOU
Lucid explanation. Please could you solve a problem on it?
think you so much
really superb, thanks a lot...
Thank you so much!
Can we get a video that explains sting theory
This is easy, what grade do you learn this because I'm in grade 8 and I don't know when you start calculus
Hi Charlie, Are you're taking physics in 8'th grade? That's odd but super cool dude. No one responded to you, but to answer your question, during your first year of high school (9th grade) most students will be taking Algebra or geometry depending on their knowledge. Assuming you start off with Geometry, the next year you should be taking algebra 2, followed by precalculus, and finally calculus. So assuming you take one math class per year like most students and don't test out of any and begin high school taking geometry you should be taking calculus in your final year of high school(12th grade). But if you want to take it sooner you could always test out of your current math class. At least that's the system my school followed when I was in high school, I'm assuming others are similar. I hope this helps:)
Thank youuu
Great explanation. So now I know what the hell flight control is talking about when the put a satellite in orbit.
Absolutely.
Delta X also approaches 0.
Am i right ?
Yes!
For anyone looking for part 2...here it is.
/watch?v=hE6loY21Nmc&list=PLnVYEpTNGNtV63F6VJ4WywoN58UEmCO1i&index=8
average velocity= total displacement/total time not distance/time that is speed!
See explanation nah, I’ve understood this stuff so well naw, my physics prof just the mad anyhow. Tsk!!
Andrea’s kzaa😂
You re god god damn
