Please please please make more
This is great, the only problem is that I don't have 1 hour lmao
Thank you!!!
randomly found it by the way its awesome. Thank you so much
i love you
Hi youhyn which online whiteboard are you using?
@@ckcmedia43 Mostly goodnote.
Hey I forgot to update because I forgot about this, but I watched most of your videos and got a 3 on my AP Chem exam
26:31 wth? I don't get it. Shouldn't 9×½g be equal to 44.1? Why is it 9!?? Like how?💀
Can someone explain it to me? Please😭
i think you divide 44.1 by the answer of 4.9 that was found in the first part
Thank you so much for the video. Can you please make new vids please 🙏? I really appreciate it because I’ve watched all of your vids, and I love your content. 😊❤🎉❤😊
Can you do energy for ap physics 1 please. Your videos help me so much!
She just saved my AP chemistry grade ❤🙏
Thank you so much for this video. I understood it easily, pls upload more soon.
Please continue this series its really helpful thank you
THANK YOU!!! You explain everything so well
Please upload unit 5
Hello Ms your explanation is amazing can you please do explanation or review for 2025 AP Physics pleasee
The best AP chemistry video in youtube, this video is so good: the contents are well organized and comprehensive ,and with some question in the video to practice, i could check my comprehension in time.Thanks very much ,i love your channel. expect your updating!
Thx very much. Also what was that sound at 4:12? Like a like squiggle. Anyway I luv your vids.
Please continue this series to rotation or something in physics, i really need it!😭
Please do a unit 5 video these helped me so much
Please make more videos for the other units, these are so good at clearing up confusion!
Can you please keep uploading more unit cram videos on ap chem? You literally saved me before every unit test and you are by far the best ap chem teacher on youtube! everything u talk about is so CLEAR! I love you so much :(
I'm glad to hear that it helped. I'll upload more when I have time.
@@academic-coach-youhyunyess please do because of you I got a 100 on my unit test‼️‼️ Thank you so much and I look forward to other units :)
@@academic-coach-youhyun please do you have the best ap chem videos on youtube
Is this video helpful for JEE preparation??
For the resonance example, couldn’t O3 (ozone) also be a triangle or cyclical structure?
at 17:13, you mention that ac = mass times v^2/r, but when calculating ac there is no mass? Why did you add an m all of a sudden?
@@Saajid113 it’s a typo. No mass for acceleration.
@@academic-coach-youhyun so what does velocity equal now? because it can’t equal square root acceleration x radius/ mass
23:47
hello is any new ap chemistry video (maybe unit 5) going to be made soon?
same question
You’re a life saver omg 😭🙏
THIS IS SO HELPFUL, thank you!!
you are Amazing thank you so muchhhh
This saved me before my test, thank you for making such a great review!
Can you continue this series of AP physics one! I really need it
same
Your explanation is great, I can listen to you without getting bored. Please share more videos about physics. I'm looking forward to your new content. Thank you! ❤
These videos absolutely helped me this year! (I took the exam May of 2024) I had been struggling and pulling out 70s/80s on tests all year but watched these videos starting 10 days before and got a 4! It may have been a 5 but I left 3 FRQs empty due to time (being too slow), so I’d definitely recommend doing at least 1 practice FRQ exam without these videos to practice timing! Otherwise, this was seriously helpful. Thank you!!
bro you left 3 frq empty and still got a 4? thats pretty damm insane
BLESSS! My ap physics 1 test on kinematics is tomorrow and I honestly wasn't feeling confident until I watched this video
NICE, YOU SHOWED UP AFTER I'M DONE TAKING IT
I love you
Hii is it okay if you continue these videos for the rest of the units in AP Chem? Your videos are the only thing that I found really helpful, thank you so much for making them
Rodriguez Helen Miller Sarah Jackson Angela
I have an exam tomorrow on this. You just saved my grade!
have my half yearly physics exam tomorrow and hopefully I pass (i will I will I will but stilllll) even tho im from the cbse board lmao
Thank you!
You are awesome, thank you so much.

Thank u so much for your videos. Can you make videos for AP Calculus AB like how u did for AP Chemistry.
Hi why don't you make a video for AP Calculus AB too
my teacher made teh first day summative the unit 1 test. life saver video
🎯 Key points for quick navigation: 🎓 The presenter, Eugene, introduces himself as an academic coach and professional tutor, sharing educational content on kinematics for AP Physics 1. 📘 Kinematics focuses on how objects move, emphasizing displacement, velocity, and acceleration without addressing the forces behind motion. 🔄 Displacement differs from distance by considering only the starting and final positions, whereas distance accounts for the entire path traveled. 🏃 The velocity involves direction and magnitude, differing from speed, and is calculated based on displacement over time. ⏱️ Acceleration indicates how quickly velocity changes, with an emphasis on constant acceleration in the context of AP Physics 1. 📊 The analysis of motion graphs, such as velocity versus time and displacement versus time, helps understand acceleration and displacement. 🌐 Projectile motion as part of two-dimensional motion is covered, highlighting the role of gravitational acceleration and changes in velocity components. 📏 The use of kinematic equations in free-fall scenarios and other AP-style questions is explained to calculate various motion parameters. 🧮 Vertical Components: The time taken for two experiments to reach the ground is the same due to identical vertical velocity, displacement, and acceleration. 📉 Graph Analysis: A tangent line on a position vs. time graph determines the speed of a ball at ground contact, calculated to be approximately 5 meters per second. ⚖️ Center of Mass: Explains the concept of the center of mass and its calculation with multiple objects, useful for AP Physics. 🪂 Acceleration Components: Horizontal acceleration is zero, and vertical acceleration is constant (gravity), showing combined acceleration equals gravitational acceleration. 🖊️ Recording Motion: Using photogates and motion detectors accurately measures a moving object's velocity and acceleration, which must align with the object's direction. ℹ️ Graph Interpretation: Selection of proper graph types (velocity vs. time) helps in analyzing acceleration scenarios, important for understanding constant positive acceleration. 🏹 Projectile Motion: Discusses the conditions and graph interpretation for launching an object at an angle, focusing on its vertical and horizontal components. 🎯 Dart and Target: Explains the interaction between a moving dart and a falling target, highlighting the relationship between their velocities and resulting positions. 🟰 The displacement of an object in a velocity-time graph is found by calculating the area under the curve. 📏 Questions about object displacement often involve interpreting graphs and calculating areas geometrically. 🌍 Constant acceleration in free fall is due to gravitational force, making C and D correct in certain scenarios. 🛤️ Objects on inclined paths generally experience constant acceleration, as demonstrated in example D. 🌌 The maximum height in projectile motion is influenced by initial velocity and gravitational force. 📊 In velocity-time graphs, the displacement can be zero if the areas of positive and negative regions cancel each other out. 🌀 An object spinning and moving simultaneously has non-zero displacement due to its translational motion. 📉 A decreasing velocity in a system suggests a constant acceleration, as seen in center of mass analyses.

hi! it is a really helpful video for students who want a 5 in their ap chemistry! thank u sooo much love u😘 but just why the video part of electron affinity did not explained the trend of electron affinity? Is it not very important in the course or u missed it?
@@terisa-820 Hello, thank you for the feedback. This was the cram study video so I was unable to cover all the details. Electron affinity is not tested as much as others when it comes to AP Chem exam (doesn’t mean that the concept is unimportant!!).
@@academic-coach-youhyun thx!!
14:33 i think youre wrong on this one
Which part? Deceleration?
@@academic-coach-youhyun no nvm i was wrong.
@@academic-coach-youhyun Can you make a video on vectors?
