Vector Components
This video shows how to find the components of a vector in the first quadrant. This is a handy skill to have in introductory physics classes like AP physics, high school physics, College Physics, or University Physics.
We start with a sample problem and work out how to sketch the vector and draw in the components. We then use a bit of trigonometry to write equations for the x and y components.
After the equations are ready, we enter the numbers into a calculator and solve for each of the components.

I absolutely hate this. I have to read out loud sometimes I’m sure every test is flagged
You're at where u wanna be in like why not help someone else get there! If they are trying to have a career and job isn't that better than them holding u at gunpoint and harming one of ur loved ones because they can't survive????
Can proctors hear me if I'm muted?
This shii weird asf so if you move wrong they detect it and you fail 😂 no wonder people don’t go to school no more 💀
its an violation to watch student while an exam, illegal
You from Ny
Violation of privacy and illegal practice. The CSU case ruled by a federal judge creates a case study, which can potentially turn into a huge issue for all institutions who allow the use of Honorlock. Also, whomever promotes the use of such spyware should be held accountable for forcing people to give up PII. Additionally, this practice favors privileged students who can afford to buy a webcam, or a computer that has one; other students who can't, will probably face the consequences, and this, to me, is plain discrimination.
This is so dystopian
* It almost represents Pythagorean theorem
Does that mean we 'feel' less heavy while on an incline as opposed to a flat surface?
@@kaeez You might not feel much different, because the same amount of gravity is still acting. The reading on the scale will be less because the normal force is less. You would notice a tendency to slide.
I don't really get how your circuit is built making this video hard to understand
I've already taken two exams for my bio class and it's the worst. first, this happened to me on the second exam, but my exam was paused like 4 times because my camera stoped cording me and this stressed me out every single time because I was nervous it wouldn't work again. second, I like to talk myself whenever I'm taking online quizzes or exams and this completely permits me from doing that
thanks bro i passed my physics exam because of this you seem very smart
Great 👍. I'm glad you were able to benefit from this. Good luck with your future courses.
oh my god my physics exam was today and it went good because of this!!!!
BOOOOOOOO REMOVE YOURSELFFFF
Beautiful
How to calculate the voltage drop of any one single resistor in any circuit
Can professors see past browser and clipboard history??💀 That's such a invasion to privacy💀
Thank you
This is actually fucking horrifying
can they spy on you even if you are not using Chrome or not on the school site ?
Your a loser bruh,
Please post more video 👍👍👍✅✅✅
I dont see why so many people in the comments are freaking out about this.. if it were in class you'd be watched by the teacher or a camera anyway. How do you expect to keep academic honesty high and credit online degrees as being valid without this proctoring service? This is just the future of education and the digital world
Accidentally just took a test without turning honor lock on. I visited the landing page to try to see some additional info, and it kick started without honor lock being started. I did really well on the exam, better than most of the class, and I'm frankly freaking out that I'm going to be accused of cheating. I absolutely didn't. The test was open book, open note, and substantially based on the homework we already did. I have no clue how the other students didn't do well. Not sure what to do, but unless it alerts the prof. that I didn't have honorlock on, I'm thinking about just not mentioning it unless she does. I feel like even saying something invites suspicion.
What an absolute joke of a world this is becoming. Forcing students to download software that sells their data, from a parent company with a terrible track record of never fulfilling their promises. A company that doesn’t disclose their encryption methods, but oh they say they care so they must be right! If you don’t understand technology enough to realize you are absolutely overstepping a privacy boundary, then gtf off the computer and proctor your exams in person, like what the student has paid for. If you’re too lazy to create a learning environment where crap like this wouldn’t have to exist, then find a job you actually belong in. Crap software like this is an absolute violation of rights, and illegal in many parts of the world. Do you really think the outcry in the comments is for nothing? You think the STUDENTS are lazy? Throw them in a room with a pen and paper and they’ll study countless hours and their scores will be better. But proctor some crap like this, and you are sure to get an outcry, its not from laziness. Its because you are flat out wrong to force students to download privacy invasive software on THEIR personal devices that THEY paid hard money for. What a joke.
Not to mention, all this does is encourage a cheating environment. You’re shooting yourself in the foot.
Let me start by saying that I no longer use Honorlock, for many of the reasons you state. The reason I started using it was two-fold. The first reason was that many schools that my students transfer to would not accept non-proctored exams. The second reason was flexibility. Many students are taking online classes because they can't be in the classroom. I have students with full-time jobs. I have students with small children. I have students with physical challenges. I have students from all over the world. It would be ridiculous for me to a) specify an exact time they need to take the exam b) make them come to campus, or c) be online for the 48 hour window in which I offer students to take my exams. I see that when you wrote this comment: 1) You were online. 2) You have a youtube/google account. 3) You didn't take the time to read my other comments related to this. I never said my students were lazy. Most of them have paid for the option to take my class online. I'd love to see them all in person. I could certainly stop teaching online. I think that the benefits of flexibility and availability far outweigh the challenges of teaching online. Do your homework before you gripe.
@@PhysicsThisWeek oh i completely understand. I’m sure you’re reasons are completely valid, and I am totally aware that there are many students who prefer and/or actually need to do a majority of course work online. My comment was mostly fueled out of an anger for own situation in which a teacher attempted to force students to use the software. And certainly not a comment that takes any other situations into account. A bit of a single-minded, angry, very hateful comment lol. I apologize. The situation in which a professor I had was trying to use the software was to me, completely unreasonable, and left me quite a bit angry, and i seemed to decide to take a lot of that anger out in a comment that ended up seeming awfully targeting towards you, so i once again apologize.
@@srgantmoomooo Thank you for your response. Obviously personal experience factors greatly into one's reaction. Many comments about this seem to be from folks who have no idea or experience on either side of the professor/student position. I realize that there are professors who use this without any consideration or thought. Thanks for the clarification and understanding. I hope the rest of your academic experience is positive.
For example if one of the 3 resistors is 6 and other is 3 and other is twelve the total R is going to be 12 devided by 7 . That's so easy i solved it without picking my pen up
Where can I purchase a rotating stool like this?
Pasco sells a platform and stool for $349. www.pasco.com/products/lab-apparatus/mechanics/gyroscope/me-6856
What if I find a value less than 90 but it's negative. Where does it land
Generally a negative angle means that your vector points into the 4th quadrant. These are measures clockwise from the x axis. -60° would be equivalent to +300°.
People who read aloud and take bathroom breaks are screwed. Also, my former classmate has a medical condition T1D and she has to take breaks to inject her meds and the professor accused her of cheating because she took a bathroom break to inject insulin privately, mind you she has accomodations to do so. I recommend people to record themselves taking the test in the room. So, you can have evidence if a professor ever wants to make false accusations of cheating.
What i like doing is reading the questions aloud, so i will get flagged doing that?? Huhu
You will get flagged. A reasonable professor would watch and see what was going on, then ignore the flag.
Bro the song 💀
So honorlock/you can only see the recordings of the room scan itself & only during the duration of a student taking the exam?
The professor can see the room scan and you taking the exam. I haven't looked to see how long I can access the recordings beyond the end of the semester. I only ever checked if any part of the recording was flagged. Watching someone take an exam is very boring.
Opposite of angle theta is always sin theta • magnitude(C)
I'm hard of hearing but I detected the one going down. At least the one with the steepest slope. Chat-GPT sent me here, I was trying to figure out what that "phantom note" or "ghost note", as I've been calling it, was actually called. I've been wondering about what that was ever since I was a kid and we all screamed in unison just for fun.
I'm glad you found the video. (Although I might be a bit scared that ChatGPT knows about me. :).
@@PhysicsThisWeek Not directly, I was looking for the name of the phenomenon and Chat-GPT provided. Then I ended up here from a quick search. :)
Book name?
I use OpenStax University Physics and referred loosely to that. You can find more details from a more advanced text like Griffiths' Electrodynamics.
If I can’t get through college because of my refusal to install this extension then so be it. I pay for my Wi-Fi, I bought my laptop and I pay for my course. There is no reason I should be monitored like this, I’m not okay with someone having access to any of what I consider to be my personal privacy. If you want to monitor and police me then you have me in the classroom, on your equipment, on your network.
I mean, I'm not being honest, I'm just being forced aren't I
That's the best demonstration of this I've seen! We use these in tuning the chanter notes of the bagpipe to just intonation against the drones
I'm glad you liked it. I didn't realize it was used with bagpipes.
So apparently this is a college thing also. They have this in my middle school..Idk if they should be doing this to minors lol its very creepy..🙁 Feels very dystopian
Such a helpful video. I loved it!
We can understand the vector movement by using the Pythagorean theorem,how fascinating
Z.
⬆️Vertical component -> Cy = C (Sin [Theta]) i.e in degree/radian . ➡️ Horizontal component -> Cx = C (Cos [Theta]) i.e in degree/radian .
At 1:51 I hear the lower tone start climbing.. At 1:53 I hear one combination tone as it slides down, but it seems to get kind of stuck at 2:01 where it breaks up into disconnected staticky beeps on the same tone, harder and harder to discern. Could that be a frequency beating between the two combination tones? (obviously not as clear as the besting that occurs between the main two)
My ears aren't quite as sensitive as they use to be, so I don't quite catch that. It is possible that there is beating going on there.
😮😅😮

thanks sooo much
