Physics 210 - Lecture 4 - Kinematic Equations & Free Fall

[kenjidao]

it's nice to have a funny professor.

[TokyoangelDesu]

Ty so much. Thanks to you I'm doing really well in my class.

[Ghaiyst]

I love this teacher's attitude on how problems need to be solved!

[nycgirl999]

Thanks for making this seem simple! I heard not to take Riggs because he's too easy on you, but he seems to make it very understandable! What's not to like?

[Ghaiyst]

@nycgirl999 Cuz Im too old for this shit riggs!

[3888799]

i got lost when he found the max height?

[Ghaiyst]

@3888799 max height is when vf=0=vi^2 +2adxmax=vi^2 + 2gdymax

so, dymax=vi^2/2g=Vi^2sin90sin90/2­g

lol this guy is chill

[TheRealCardshark87]

thanks, much better than my shitty teacher :)

[neyeseecay]

I found an iPhone app called "Kinematic equations Solver" which helps with these problems a lot! :P

[JadedHeart8]

lolz "she doesn't bite too often" Dude this guy is hilarious and a nice teacher who can teach ^_^

[fuzzyhunty]

i wish this guy was my teacher

[SQTvsTECHN0]

Thanks alot, very handy indeed.

I love these lectures. I used these lectures as a review for my Physics section of the MCAT. Trust me they work! ( Note, study as well, but used these as a warm up and take notes as well.

[luv2yap]

this was great! he explained it so much better than my prof did!

[TheRochelleJ]

Thank You for this video my professor makes sense in class but when i get home i am dumbfounded.

[destroier113]

thanks a lot for the video,

i'm studying for my final exam and

this is very helpful for me.

[kahllah]

this man is awesome, and he is sOOO NOT boring?!!! thank u thank u thank u!!

[DCskate714]

if you check out (Deriving the Kinematic Equations (part 1)) you'll understand the equations better.

[DCskate714]

wait how come the Vo is 19.6 in the first problem and Vo in the second Zero when he uses the 5th equation? Vf^2=

[jcariasgomez87]

it is because he is dividing the problem in 2 parts, so and when you let something fall in a free fall the V initial is always zero

[Sakilaire]

@jcariasgomez87 Not always is zero, the final can be, but the V initial no always.

[TengoNoNombre]

actually i didn't get it, too many formulas

[narutofangirl]

thank you for posting this it will help me get through my physics class in high school. My teacher cant teach at all. Thank so much for this!

[angel209056]

thanks, this helped a lot. my high school physics teacher makes absolutely no sense.

the professor is much easier to understand.

[IronCellist]

Same thing here!

[lindsey47646]

@angel209056 YEP!

[Thatfatguyfrommars]

@angel209056 I think the flaw with most non-understandable teachers in high school is that they make it hard for students to ask questions. I can sort of get the issue with that in college lectures, but, I mean, that's different. My physics teacher right now in high school right now goes so fast and what makes it worse is that he has a freaking heavy accent so me and half the class has no clue what he's saying.
