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! :)
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.
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
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.
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
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.
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
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.
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.
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
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
You're a king, a God, and my diety. I hope you know how much good you are doing in this world. Everyday you should wake up knowing that you are changing people's lives for the better
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
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.
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]
I've been searching all over youtube for tips on how to solve spring/pulley problems regarding harmonic oscillations. I cant seem to find any videos in english
What more can I get before I can describe someone as an angel? You have been exactly that-An angel, any other word is an understatement. May God bless you and your family for your videos, I must confess, I have been richly blessed through them
If I were to try and find out the frequency of a bond, could I use this equation or must I resort to quantum mechanics? For instance, a C-H bond has a reduced mass value that can be found using the atomic masses of Carbon and Hydrogen. From there, how would I find K?
