Omg he doesn't have a grand children 😂
When I make a steady income im definitely donating at least 1k to you. STRAIGHT UP LIFE SAVER FOR SOOO MANY YEARS. BLESSSSSS YOUR SOUL
did u donate yet
Got a job yet?
@@aayaanfarooq9427😂😂😂😂😂
Been watching a lot of your videos and I just have to say... you’re an amazing teacher and honestly explain physics a lot better than a lot of (my) professors. Thank you! :)
Are u in university?
i am and i can confirm@@of_te_n
How tf does this dude know EVERYTHING. He's helped me with Chem, Calc, AND Physics now this is insane.
😂😂😂😂😂😂
BLESS YOU! U have cured my SHM depression
I’m here the night before my AP Physics 1 exam 2020. Anyone else?
me
Good luck! I'm here for ap as well.
Nah, just trying to pass college physics now 😭
I just happened to be here because I got tried of Netflix bullshit and TV comedies. This is more entertainment for me.
Currently watching while doing my uni phys exam
We can easily prepare one night before exam.. by. This tutor. 💪✌️👍
EXACTLYYYY
@Kellen Erskine lmao i have mine Friday and have binge watched this channel, I hope you did well
Exactly
@Kellen how'd calc2 go
@Kellen damn lol u got dis. i ended up w an A in calc 2 and takin calc 3 rn
This is almost a chapter review. Keep it up! Thank you very much!
I honestly don't know how I would survive without this CHANNEL!!!!!!!!!! I LOVE YOU!!!!
Brilliant. I understand. I SEE THE LIGHT!!!! AAAHHHHH TYSM!!!!
Your a wonderful tutor, fluid mechanics was a challenge for me back then in uni, never really understood just read to pass.
Always really wanted to understand, watching your video as really aided my understanding and appreciate the practically application of the principles.
Thanks a zillion.
Wow,You such a passionate tutor.Am always grateful once I watch your tutorials
God bless you, I swear you have helped me so much throughout the whole school year, thanks to you physics gets less and less confusing to me, thank you so much, I can't find a way to express my gratitude so I will just leave this here even if you never eventually notice it
Honestly I am aversion to all these formulae but after watching this video I can't have enough of it. Honestly I couldn't be better. Thank you so much you are so a life saver.
Thank you so much for making things so much simpler than how profs explain...these things go over my head in class but doing these problems with you really boosts my confidence!
do you know what class this is at your university if you're still there? we are learning this +more in our high school physics class so im wondering if ill have to learn the same thing again later
@@zo0m524 I was learning this material in my general physics class. I only had one physics class in college. Hope this helps!! Good luck with your studies :)
@@zo0m524 AP classes cover introductory college class content. So what you're learning in AP physics is likely similar to what a college freshman is learning in their physics class. Depending on how well you score on ur AP test, and which school you commit to, you may be allowed to skip a physics class in college.
@@zo0m524 It's normal to learn physics in high school, in mine it's mandatory to take it if you want to graduate but some will allow you to skip. In college, it's usually gonna just be the low-level physics where it just goes over the main important stuff about physics. I'm graduating in a few days and going to be majoring in physics and while I was talking with my advisor about what classes to take to get the degree, the first physics class is basically almost everything I covered this year in physics.
@@Andrew-fb8ph its not even AP physics though this is our honors class, our AP class is way way harder
This was extremely helpful, thank you so much.
Thank you, this was so helpful!! Also a quicker way for the last question is to use the formula T = 2 pi * square root of (m/k), and just rearrange for k since we have the other variables
from organic chemistry to calc 2, to physics, you and you alone have saved my grades and made life so much easier, thank you from the bottom of my heart man
Literally can't thank this guy enough, and when it comes to RUclipsrs, he is definitely up there with Kurtis Conner.
Everything is so simple when you explain and is so easy to remember... Thank you 🙏
Yet again, youtube proves to be a better teacher than a 90m university lecture.
Thanks so much man!
Still the best teacher I ever had
Nice tutorial, you took all of them one after the other
I have never commented on your videos before.. even though I have been following you and referring you to others.. this lesson gave me a better understanding.. thank you so much
Thank you so much! I always watch your videos for ALL of my classes, and ever since I've been getting all A's. Thank you thank you thank you!!
MMM wow really
you say thanks for watching and i say thanks for teaching.
thank you, I really appreciate your work
You might be the most helpful person ever
thank u thank u. you're a brilliant teacherr! god bless
Your channel is super helpful and God bless you for helping us out. Thank you so much ❤
god bless you, you have such a calming and reassuring voice. You have helped me so much :)
You really helped me solve these harmonic quiz thank you very much.
got a test in 1 hour, your taught me more than my teacher has lol
You are so good, i must say
Physics and Chemistry are 10x easier now thanks to your videos. God richly bless you👍👍
You really helped me , thanks dude
great work keep it up thanx
THANK YOU SOOO MUCH it is 0:38 and you help me a lot god bless you
Thank You! The AP test is in two days and this is the last thing I don't understand
thank you for the video it was really helpful to me
Thank you so much!! WOW! Thank ya mama and daddy for having you please sir!!
YOU are the BEST brother
Great work!!!!!!
thankyou so muchhhhh sir!!! always grateful 🙌🕊🏆
You're the best man.
Thanks for the video
best teacher in the all world
great work done
thank u, u helped me a lot
please can you make a video for centro-id gravity for engineering mechanics.thanks for your hard work..
can you make one on how to find phase, and speed point using this equation?
All dout clear 😊 thanks alot
you're a good man
Thank you
Nice review!
This is a nice set of practice problems! However, the statement of Problem 3, should specify that the mass is the same in the two scenarios. Otherwise, if the mass is not the same, the cancelling method would not work. You can also use a method to find the mass itself in Scenario 1, it's 4.05x10^-3, and then plug it into Scenario 2 to find the frequency.
Sir u are a genius
Thank you my man
currently your saving my lifeeeeee
You're Amazing 💜💜
Nice exercises for practice
An organic chemistry tutor teaching Physics interesting!
Honestly he needs to change his name to “The Tutor.” The man knows everything
Thank you so much
Thanks so much
Thanks for your hard work. You should earn 1 million dollar by helping other.
Mate you are the best!!
When I'm no longer a broke student, I will donate so much money to you. You have singlehandedly saved my academic career from high school to university. God bless you.
thank you sir God bless
Thank you ily so much.
Thank you!
For the second question, should Force = - k * x or Force = k * x? I've seen negative for SHM but noticed you just left it positive so I'm not sure
the minus sign is only required if you write the vector form of the equation, because the force vector is always pointing towards the equilibrium. In most equations you only care about the intensity of the force, not the direction, so you can leave the minus sign and just use F = kx
İ don't know how I express my felling but the only thing i can say thank you uncountable times.
Thank you so much...
we can easily calculate t=2pi*root(m/k) and finally value of k
My every year routine
Pay lot of money tih coachings and then study from thus channel . BTW I have my exam in 2 days will edit this later
YOU ARE AWESOME
Bless your soul 🙏
If only school and college was about learning instead of a business that gives you a stupid diploma for a job, no doubt this guy is my savior.
very useful
Thanks
your better teacher than my professors
Amazing
The living legend❤️
thanks for saving my aps
thank you for everything mwah😘💋💋
Thank you sir for your guidance
How did you determine the formula for frequency, I noticed that the formula was different from example one than it was in example 2. F= 1/T vs Example 2, F= 1/2pie [K/m]
so whats that t inside of the cosine ration in the x position formula?
salamat, unta mabuhi kapag dugay🥺
Thank you sir. The Lord bless you and give you infinite wisdom
You're such a good tutor. Heart you Big.
Pls can someone explain to me how he calculated the 2π√0.75/300 to get 0.31425
How can I press my calculator to get it pls
Thanks boss
It would be super cool if my teacher actually taught me this
Awesome🖒
3:48 Okay, I'm having difficulty finding the Spring Constant in a problem I'm working on. All I'm given is the mass (m=10kg) and the frequency (f=4 Hz) in a vertical simple harmonic oscillation. I need to find the frequency when the mass is 85 kg. How do I find k from here if I don't know x? Or I guess how do I find x from the weight and frequency? The only force acting on the object is gravity.
When m= 85kg
f= 1,372 Hz
Using same K= 6316,55N/m (drawn from the formula of frequency with the first given coordinates of m=10kg, f=4Hz )
Then use the same K found to substitute in the equation with the new mass of 85kg to find the frequency.
For question 1 part b
I got f = 31.4Hz
I did this with the eq. (1/2pi)(sqrt(k/m))
How do you know which equation to use? Because they both give different answers
Your equation is correct. You probably are making a calculation error.
300/0.75 = 400
sqrt of 400 = 20
20/6.28 = 3.18 Hz
@@MAXYANKEE5 where did you get the 6.8 from? (1/2pi) is 1.57 and 1.57x20=31.4
I got all of them right😎😎😎
love u bro
