My physics teacher threw equations at us with no explanation and I was getting so frustrated. You made it make sense in four and a half minutes. I'm in tears, thank you so much.
The same happened to me when I took a physics 101 course at UCI. It was expensive and I could barely understand the professor with his thick accent. He never explained any why or any motivation. There was no discussion of Newton or the history of the subject. Problems were presented and worked through just out of the blue. Things like the meaning of "normal force" were not explained. Absolutely terrible. 20 years later I'm deeply passionate about physics, no thanks to that experience.
@@blablablablablablablablablblaI mean the history is not needed to understand the equation, if we had a history lesson for each equation we’d never get anything done
@viceturtle2889 there's truth to what you're saying, but sometimes understanding the history of something is important for understanding it. I would say that about most of quantum mechanics. Specifically, awareness of what experiments led to the current understanding is important. Because without "measurement" typical qm cannot be understood. I think that generally an understanding of the historical context is very valuable.
Thank you sir, this explains everything before the final exam. Much better than how my Russian teacher teaches it by throwing in random formulas with no explanation 😂
It's valuable to know that moving an object is mostly about the work being done, and not just the force. Not in every situation, but I've encountered a lot of situations where applying continuous force on a seemingly immobile object caused it to eventually move, including machine screws.
because vf is your final velocity, but you have not been travelling at that velocity for that amount of time. you started with vo and ended with vf, so your average velocity is (Vo+Vf)/2 and you multiply your average velocity by time to get the distance. hope i was able to assist
This might not be the explanation you are looking for, but being a mathematician I would expect the following: Given vF = v0 + at we get vF^2 = v0^2 + 2v0at + (at)^2 = v0^2 + 2a(v0 + 0.5at)t where the last part from the parenthesis is the average velocity, (v0 + 0.5at), times the time t, which in turn is exactly the distance d. Hope it helps, but feel free to ask!
Well, if we use D = Vo + 1/2at^2 since we have a = 8 and t = 8s, we can figure out the displacement which should be 256 and then just multiply it with force making the overall math easier.
Thanks Jesus loves you!❤✝️Repent and God bless Blessed is the one who does not walk in step with the wicked or stand in the way that sinners take or sit in the company of mockers. Psalm 1:1
You just round it off...so we see that after the decimal point, the first number is 9 and since 9 is greater than 4, you'll add 1 to the previous number which is 5, making it 6. That's how he got 376

IM LITERALLY IN THE SAME SITUATION but with my chem professor!! but i got it too AAHHH

I dont know why but I found it hilarious when you said that work is mad.
lmao yea
When?

Yeah

Timing was on point with my physics class!
Best teacher ever thank you so much ❤️😊
Good
Best math teacher thanks bro I hope you continue

Good physics lecturer ever😊,greeting from 🇳🇦
This dude is the reason i'm not failing Physics rn
From Egypt
Thank you for everything ❤
This was the best lecture video. ❤
I love ur lectures sir❤
what i hate is theres so much variation with physics it gives me anxiety. At least chemistry generally has a direct path. I hate this stuff.
Much needed thank you!!!!!
We sorta need the thin lenses last one u uploaded was 7 years ago
U are amazing I swear!!
Can you do a video on relative motion ❤🩹?
11:8 when we calculate the displacement using the formula Velocity=distance\time we get 512m
Perfect timing to come out haha!
Can we get a face reveal at 7 mil?!?
How bout you mind yo own beezwax 💩🫵
No I don't want one
Real
Jesus loves you!❤✝️Repent and God bless
Can u explain why u used distance = 1/2 (Vo + vf)(t) , instead of just distance = (vf)(t) ? Thanks 🥹
because vf is your final velocity, but you have not been travelling at that velocity for that amount of time. you started with vo and ended with vf, so your average velocity is (Vo+Vf)/2 and you multiply your average velocity by time to get the distance. hope i was able to assist
Because average velocity is 1/2(v0+vf)
Jesus loves you!❤✝️Repent and God bless
Thank you so much
Thanks
Thank you
*** In this video *** we will talk about work and kinetic energy.
What platform do you use to write the lecture notes on?
Looks a little like gimp
"The work is mad"
Thanks
Thanks for the video
GOAT.
Where does the 2 in 2ad come from?

I like this
Bro cooked fr
I love you
Yup! Work is very VERRRY mad
i love u
Again I have different answers for both questions.

This is a chemistry video don't bring religion here 👍
@@nostalgictunes10 you could have just mind your business
@@kobiruo_mila9no he shouldn't, everything has a place and this is not that
For youu!!
@@kobiruo_mila9yes go mind your own business and quit preaching everywhere
How did you squared 19.3907 to 376 when the answer was 375.99924649
I am so confused on that i just think they round the numbers but idk how and why!
@@GisselleFunez Likewise!
You just round it off...so we see that after the decimal point, the first number is 9 and since 9 is greater than 4, you'll add 1 to the previous number which is 5, making it 6. That's how he got 376
Ohhh, thanks! Because I was genuinely confused.
