- Chad provides a comprehensive lesson on everything related to Vectors and the role they play in Physics. He begins with a trigonometry review covering the trigonometric identities commonly used in working with vectors. He then defines a vector and explains the difference between a scalar vs vector quantity. He then shows exactly how to split vectors down into x and y components explaining the standard of using the angle with respect to the x-axis. Finally, Chad demonstrates how to add two vectors together as follows:
1. Splitting vectors into components
2. Adding the x and y components together separately
3. Combining the x and y components using the pythagorean theorem to find the magnitude of the resultant vector
4. Using the tangent identity to calculate the direction (angle) of the resultant vector

Great to see your face. Thank you for keeping us updated.
Glad to be seen - enjoy the new playlist!
Thank you so much for the update Chad! Your lectures are very motivating and filled with knowledge and fantastic explanations!
You're very Welcome - Glad you like them!
thank you very much! best vectors explanation i've ever seen!
You're welcome and Thank You!
This is it💃
The way you teach is exceptional,
I've been going through Google and UA-cam to get a clear understanding on this topic and you just made it happen, thank you so much for this video.
Fantastic! Happy to hear you found this helpful
Hey Chad! I've been watching your videos for ages, your ochem playlist was the reason I aced my final exam. I'm busy doing revision for my upcoming mechanics exam and the trig review literally just solved half the problems I've been having 😂 Thank you so much for these videos, you're the best lecturer I've ever had! 💕
Glad it's helping - Happy Studying!
you are a lifesaver for the mcat!! Also love the messages in the shirts!
I'm saving up to get your mcat course but in the meantime would you recommend the 2023 or the do you think the older physics playlist would be sufficient for the mcat?
I have the uworld question bank that I bought a while ago for practice Questions and I'm saving to buy your course too hopefully!!
Here again on your channel after gen chem 2’s success; you’re the best, dude! I want a shirt with your logo on it!!!!
Welcome back - no clothing merch but maybe someday. :-)
Thank you so much Chad, your videos have helped me understand physics much better than my professors could teach me. Also, I love the shirt, and may God bless you my brother in Christ!
You're welcome and Thank You!
thank you king
Very welcome!
Hey Chad! Unfortunately, as a high-school student, I can't afford the fee for work-problems, I'd like to know what textbook you've used to structure the playlist so I can hopefully book it out at the library. Thanks!
May I ask a question? Can a vector be greater than another vector (not its magnitude)?
I'm quite confused about this since my teacher said that if vector(a) = -4i and vector(b) = +2i, then b>a because 2 > -4.
Power to your brain!!!!
Fill it up - Happy Studying!
Lesson was super helpful,,,do one about projectile motion🥲

Hi Chad. Are you going to upload more general physics videos on the 2023-2024 playlist? I find it so organized and helpful!!
Overall, the plan is to release a few lessons per week to mirror when students are likely to be encountering the topics in their university course. Stay Tuned and Happy Studying!
I'll be releasing chapter 2 next week with the first lesson on Monday morning 😊
@@ChadsPrep Out of curiosity, is the play list on chadsprep general-physics 1,2 complete? or is it from the old physics playlist?
Wow! thank you o much for this. Would it be possible to explain why on timestamp 26:43 we used 60 degrees and not the 30 degrees. i know you explained it in the video but I'm not grasping it. plz help if possible thank you.
Hi David! The emphasis is to always use the angle with respect to the x-axis (instead of the y-axis). As long as you do, then you will use the cosine function to find the x-component of the vector and the sine function to find the y-component. If you use the angle with respect to the y-axis this would switch. While you can do it either way, it is much less problematic to do it the same way every time. Hope this helps!
hey chad, is there any chance we will ever see chemistry again on your channel? perhaps organometalic or advanced organic chemistry?
Planning on a new biochemistry playlist next year. Physical chemistry and even analytical chemistry I can see myself doing, and even a more thorough treatment of organometallic chemistry. But advanced organic isn't likely. There are better instructors than me for such an undertaking :)
nice
Excellent!
Chad, is your MCAT prep course the same video material as the ones on UA-cam, or do you teach the math for the purposes of the MCAT since there is no calculator allowed?
Hi Isabella! You hit it exactly. The MCAT version is taught from the perspective that you won't have a calculator, so I present tips and tricks along the way for doing math in your head and restrict the examples used to those you might reasonably be expected to do in your head. I also follow the AAMC outlines topic list very closely. You'll note that some topics you will see in the college course are not likely to appear on the MCAT. So the MCAT version is very targeted to the test making the whole series 30-40% shorter in duration. Hope this helps!
Thanks Chad! I just purchased and noticed the videos mention the 2015 AAMC guide. Have you seen any major changes by the AAMC in the more recent outlines, 2023, 2024 et cetera? In other words, is it safe to rely on all of the content being taught by you in reference to the older AAMC outlines? @@ChadsPrep
2015 was the last MAJOR revision to the MCAT, and it was pretty significant compared to earlier versions. But the changes since have been more subtle, and the MCAT outlines have remained pretty static since. I do plan to make a new set of MCAT videos this summer, but the most significant content updates will be to the Biological and Biochemical Foundations of Living Systems section. The most significant update overall will be audio/video related rather than content related. The chemistry and physics will see some very minor changes with a little more substantial changes to the Biology/Biochemistry content. In addition to the MCAT outlines, there is quite a bit of material available in the form of practice packs and practice tests that have influenced the coming changes. Hope this helps!
