I know it’s too much too ask, but timestamps in these kinds of long videos would be extremely helpful. Other than that, very well explained and you’re a without a doubt a lifesaver!
I failed my first and second tests on my first semester, but then I stopped attenting lectures and started watching your videos a few weeks before the exams and passed it. Thank you very much.
its like their only job for 20 years is to explain one subject to a group of students and then there's some guy on youtube who makes videos on 500 other subjects that can explain it so much better
up until this year, I have never struggled with a subject, but then I took physics. before I found your videos I had a 76, and now I have brought my grade up to a 91 with your help. thank you from the bottom of my heart
You literally helped me get an A on a test that i had no idea of what to do. I watched your video 2 hours before it. Thank you for providing this amazing service of your time and knowledge. May God Bless You!
I wasn't sure if I was willing to spend 2 hours doing physics but time flew by so quick! I really enjoyed that and the explanations were very clear. Thank you!
This has to be the best lecturer I have had so far. Explanations from this tutor are nothing like I have heard before, he explains better than our university professors. I dont even have to attend my classes anymore
Genius tip @ 13:57 about plugging in the variable values into the formula (as change magnitude where 1 = no change) to see the resulting behavior change. Much easier than I've always done it!!
“It turns out that 1 kilometer is 1000 meters” what an amazing discovery lol. P.s thank you so much for your content, you genuinely make me more confident that I will do well on my physics tests.
How can anyone dislike these videos when they are god-sent? Literally, sir Organic chemistry Tutor you are a magician. I said it! or wrote it, whichever works.
Your a lifesaver man. I barley even pay attention in lecture anymore when im in a class that you make videos for because I know about a week before the exam I can just watch your videos lmao. Thanks goat
Tim Kidd; he is better than everyone. Yeah i dare to say that. His style of teaching is best while salman khan is better than others *but* not better than The Organic Chemistry Tutor. TOCT is the best teacher in my life.
TOCT is so good because he spends more than a hour on each set of topics and get into the nitty gritty. In comparison to Khan TOCT has more in depth video, thats y i love himm
You are butter than my Professor. I passed calculus II and now I’m taking physics 1250. I feel confident because of you. please keep doing tutorial videos.
If I could like this video more than once I would, because you just explained my entire physics unit better than both my dad (an IT specialist who's had to learn this) and my physics teacher!
1:01:30 the answer for net acceleration is done right but due to intermediate rounding the answer became off by 0.4 In this scenario, 0.4 is a slightly large difference since the answer itself is less than 10. Rather if a direct input of the v^2/r in the Pythagorean equation then it would yield about 5.26. You taught the right way but it was just off due to rounding. But still you helped me learn how to approach these problems
Not all superheroes wear capes🤧😭😭 you a superhero irl brooo💪💪💯 saved myass frrr I missed 2 weeks on some family situation & you were the only person I could actually quickly learn from, and taught in such a comprehensible way, it helped me rlly understand rather than just remember lol🙏🙏much love mann!
May I please know your level of qualification? because you explain things extremely good, more than a University lecturer. may GOD bless you abundantly.
Great video, but one question. At about 46:28 did you just not count the tension force for the Y component when calculating the overall tension force because the Y component tension is almost negligible? I counted the Y component and got 29.7 N instead of 29.6 N.
Honestly, with the amazing tool of the internet and proper motivation, anyone can learn anything nowadays! Thank you for posting these videos! You helped me through General Chemistry 1, also.
8:49 in this example, I would think that the normal force is balanced by a force of the magnitude of mgcosΘ and in an opposite direction; while, the acceleration along the direction of the velocity is due to a net force equal to the (mgsinΘ-friction) force. At the initial point when the moving object is no longer in touch with the ground i.e. when the gravitational force is not balanced by the normal force, the object accelerates downwards by gravity.
The force causing the vertical acceleration comes from the centrifugal force. This causes the swings to move at a faster speed which then ultimately leads to the swings moving outwards and, in the direction, going up.
salute!you are the person that I understand without asking "why" cause you tell before I ask.GOD bless you..you really should have patreon account if you don't
35:21 I got a question. Shouldn't the forced acting on the ball at point A be T-Fg because only T is pointing towards the circle. Point C should be T+Fg because both T and Fg are providing the centripetal for, so they should both be positive
The circular motion and, the effect of magnitude of radius on the time period of an object was investigated in this practical. According to this the relationship between the radius and the period as follows, T 2 = r According to the collected data it was able to prove that above statement.
Kepler's third law had me take a break for a while and then comeback later.. my head was going to explode.😂😂😂😂......... Otherwise this is nice content your'e definately a lifesaver.
I love this channel! I have been using it for years and it’s wonderful!!! This is like the only way I’m surviving school... you got bomb ass examples and thank you!!!
Hey I think you made a mistake at around 35:00, the tension at the top is equal to the sum of the weight force and the centripetal force, and the difference of them at the bottom.
Archer i’m thinking the same thing too but thinking about it it kind of makes sense because at the top the tension would be less than the tension at the bottom since gravity is helping the fc at the top and relieving tension, and at the bottom fc is trying to go up wards and gravity is pulling the opposite direction, increasing the tension. so the tensions there should be T at point A>C which proves his equation but i also get what you mean so i’m very confused lmao
Nope..actually it'a correct...he said that centripetal forces are positive when the direction is seekin to the center of the circle..He wrote it as Fc=T+Mg at the top since both Mg and T are directed through the center..and Fc=T-Mg at the bottom since T is directed through the center and Mg is away from the center :)
it has been 5 years that u made this video. I am not sure whether u r gonna answer my question or not. But still, (56:39) u solved Normal Force equals to mg/cos. What makes it different from the other questions that the normal force was usually mg x cos? why makes the normal force to be mg/cos? Also, Thank you for making these videos. I like how u explain the general concept first and then u solved questions that are related to the concepts that u just taught.
One thing that really helped me understand the free-body diagrams is that remember that fNET= Fac all the time. So in the roller coster example, at the bottom, Fnet= Fac= FN-mg and then at the top it is Fnet = Fac = mg - FN
1:07:10 I want to understand. you said that if the speed exceeds the value that makes the normal force equal to zero it's going to fly off the road. but if the normal force was already 0 the car will lose contact so the normal force needs to be little more than zero, not exactly zero. isn't that?
I had exactly that question. The question ask me the acceleration which i calculated and find 4 m/s2. But in answers i saw in two choice the number 4. The first: constant, with a magnitude of 4 m/s2 the second 4m/s2, pointing the center of the circle. Thanks God that i watch your video.
For those that might want some more Real Life Problems on Circular motion, I just released a video where I solve such problems step-by-step. It might help some of you :) ua-cam.com/video/O2pqU_n-8j8/v-deo.html
At about 40:00, I solved the problem by using F= mv2/R which is totally different from his solution. But still I get the same answer as his. Is my solution a right way? If not, why?

@@TheMarax I hate my teacher, he is so disoriented.
There's a fine line between someone who can teach and someone who has a PhD, they have zero correlations.

At 36:43 isn't it supposed to be T+mg=Fcg for the top and T-mg for the bottom?
yes, because mg points downward along with Tension at the top.

Same here. Idk if I just got lucky or what
The equation he used is just a manipulation of the f=mv2/R equation. So he did the same thing you did just simplified it
He just solved for v in that equation...
