some tranquility, pls

i am chinese and i am no where near as good as a chinese should be.... i phail...

[daveco5417]

Thumbs up if you want him as your physics teacher :-)

[TheHairyPillowcase]

Great explanations on the basics. Thank you very much!

[JJudd93]

thanks for the upload

[cathe1509]

@bbob423 well said :)

[Ridghost]

Thank you, this was great help in the area i was struggling. (U wernt going to fast :P ) Thank you :D

[kockmunch]

@donylee Thank you, i have my A-level mechanics test this week and this lesson was really useful. Dont listen to Chensiaping, you have the best attitude for a teacher because you give up some of your own time to help and teach others. thanks again :P

[Jasminescarlett]

That was awesome thanks. I have my final Physics exam next week, fingers crossed.

Your video helped me loads thanks! x

[subway987]

+ C!!

[kojiki1976]

Very useful, thankyou.

you rock, if these people think you have attitude they are too weak for science go take a painting class you wimps

[skyfaze]

for the people who are confused by him its because your knowledge in physics is elementary

[amino0o]

Helped me alot. Good work , worth my time.

[ctw005]

Thank you so much. That was really helpful. I had to pause and go back a few times to see the manipulations you were doing, but that only helped me understand it more. Now to practice deriving the equations on my own!

[syberraith]

Thanks Donny, I found that helpful too.

An airplane accelerates from rest to the end of a runway, which is .70 km long. How much time does it take to reach the end of the runway if the plane's acceleration is 4.25 m/s/s

GO

[ShirleyBassey90]

Thank you so much...this was really helpful!!!

Excuse me sir I wish you were my physics teacher because right know I'm having a litle trouble with projectile motion and hope you can help me. (I'm just a 9th grader)

[jn30]

im surprised you are learning kinematics in grade 9. good for you for looking it up on youtube!

[Philosophical101]

Pretty cool im doing molecular physics and quantum physics, like how everything is pure potentiality until a conscious observer interacts, causing a reality hologram from perception.

[lepigeon]

Quick question

At around 3:40 you say that you can substitute v for u+at when you integrate...perhaps this is a notational error or maybe im just confused, but you wrote integral from a to t of u + atdt not (u+at)dt...was that a typo or am i missing something?

[Craggles17]

@lepigeon form 0 to t and using a brace every time you had to integrate would drive everyone nuts.

[thektulu83]

Good lesson. I hope to be a high school teacher someday so in teaching this I'd probably take a similar approach but minus the calculus. Well done.

[magipablo]

good video and good math

[hecktorzr]

Yeah! Very helpful, thanks a lot.

I think speed is quite fast but it's not so bad, you can pause and review the missing parts.

OMG I'm having an exam tomorrow!

[thecosgrove]

Thanks. You are a natural teacher.

[fxfire27]

Wow, lost me at the integration, but then again I'm currently taking grade 12 physics, and calculus doesnt start until next semester :P Nice video, probably be more help to me if I understood all the math :) I'm just glad that the formulas are given to us for my level of physics haha

[br0kensun]

that made sense , very helpful :)

[tekiemy]

LOL I have no idea what he is saying sloooow doownnn. Breeeath hehehehe Good thing I understand a bit of the formulas. :o)

[donylee]

Yup tekiemy,

Totally agree with you. I always get a little excited especially towards the end. I need to slow down. :-)

[ungell]

MM nice if i spoke japanese it wouldnt matter because i understand ur writing :)

[donylee]

Hehe, I wasn't speaking Japanese, it's the good old english.

It's great your understand my writing. I take it that it was a good lesson?

[chensiauping]

Excuse me, but if you want to become a teacher, it would be best to lose that attitude.

Just some constructive advice, hope you don't mind.

[donylee]

Hey chensiauping,

I don't mind at all. I would like to sincerely apologies if I sounded condescending in my comments. I do value what ungell said and thought mentioning the term 'good english' would serve as some humour if he couldn't understanding my speech.

In all seriousness, I always at best try to maintain a humble attitude in learning, and more so in teaching, because my knowledge is due to the great professors, through books or lectures, who taught me. I'm just a student passing by.
