How To Physics
United States
Приєднався 2 вер 2020
How To Physics is a flipped learning experience designed by Mr. Larrison who is a high school physics teacher in Cincinnati, Ohio.
Terminal Velocity and Resistive Force
Terminal Velocity and Resistive Force problems are an IFYKYK kind of physics problem. Also known as Drag Force problems. This video goes over easy steps for a full solution. We begin by writing an equation that can be used to solve for velocity, then derive an expression for terminal velocity, and finally solve for v as a function of time. Position, velocity and acceleration vs time graphs are also shown. This video is made with AP Physics C Mechanics students in mind who have to write a differential equation and use some calculus to solve for velocity.

thank you!!!!
thank you so much for your help ❤
No problem!
I know the beginning like which graph is going up or down but I’m struggling with drawing the acceleration and velocity of each position time graph
Where do u download it?
Thank you for the explanation, you're the perfect teacher. I'm glad to have found this video
Thank you!
What graphing calculator do you recommend for ap physics c mechanics. I’m really lost i dont know what to get
Ti-83 or higher. Ti-84+ CE seems to be the most popular.
BEST PHYSICS TEACHER. Wayyyyyyyy better than flipping physics. Really helpful. Can't thank you enough.
Wow, that's high praise. Thanks!
Where did a 100 come from? Cause I was taught that you have to multiply 10kg x Gravity. So 10kg x 9.8 = 98N
These videos are made with the AP Physics test in mind. That test allows students to use g=10 m/s^2 so they can solve problems a bit faster.
You are too good sir
Thanks!
God, I am such an idiot, thank you so much for helping me practice. I am such a visual learner, the graphics help out so much. God bless you
No problem!
I'm taking a summer class in physics and this cleared up soo many things for me. Thanks for the help, I'm subscribing!
Glad I could help!
dude thank you so mush
Glad this helped!
While making video first swallow your saliva and speak
i've literally been trying to understand this the whole day.. i watched soo many videos but this is the one that really explained it in a way i can grasp... thank you so much
Glad it helped!
This was so clear and easy to follow, thank-you so much!
Glad it was helpful!
Yo I had to come here and relearn this part of physics to settle an argument. Ahaha. If you were wondering, the argument was whether a pistol slide (that uses a spring) exherts the same amount of force from full compression as opposed to when it is partially locked. It sounds dumb but a manufacturer of a very very very expensive 1911 is trying to say that dropping the slide into battery while it is empty is bad for the components and the other side is laughing at them because a weapon is designed to take 20k+ psi of force when firing a round. My argument was that a spring's force is a factor of how much energy is used to compress it fully vs where it is when compressed partially. The argument is wild. It's actually turned into a biiiiiiig debate in the UA-cam gun community. If you were to chime in with the math you could settle the debate once and for all and maybe get you some traffic lolol. 😂😂😂
“O baby it hertz so good”😂
thanks for the video
been struggling so hard with mechanics problems involving stacked blocks, this was very well done bro, thanks alot. 🙏
Glad it helped!
Great help 🎉
Glad to help!
Love your videos---by any chance do you have any videos on maybe another channel for AP Physics C Electricity and Magnetism content?
I do not have other videos on another channel unfortunately. I am working on E&M content currently however! Probably won't have any new videos until next year, sorry!
@@HowToPhysics all good. I suppose I won’t need it anymore but I’ll make sure to recommend it to my friends who will. Thanks for all the help on mechanics!
That last problem was surprisingly simple
* Eric Wareheim mind blown gif here* I UNDERSTAND NOW
Wooo!!!!
if the acceleration is not constant, how we assumed that acceleration is constant? if we think like acceleration is varies by time what will change? thkns for video
you know it’s gonna be a good day when there’s a new how to physics video 💪
Ha, thanks!!!
You said T1 is equal to T2cosθ, but what if T1 has a given angle? How do we solve that
divide t1 by cos theta ig so
Haven't been getting this chapter for a while. Glad I checked this video out!!
Glad it helped!
Haha I'm just now trying to go over this lesson more in-depth. This video was good timing for me
Glad to help!
i'm so glad you're back! please continue posting, your videos are really helpful!
This comment means a lot to me, thank you and I'm glad the videos are helping you!
Your teaching style is very helpful, it makes these topics seem less complicated. Thanks! Also: Why does the point mass have initial angular momentum in the second problem but not the first one? Is it because it started with a velocity?
Thank you! And yes, you can think of it as linear momentum turning into angular momentum too if that helps. I agree that it's a little weird to say that an object moving in a straight line has angular velocity :)
Awesome video, just would like you to confirm if you are gay because my gaydar siren was blaring when you described the features of the car and my new dog. Thank you for the video!
Correct me if I am mistaken, but if Ma=Mb is the angel after collision always 90 degrees?
At 14:10 why didn’t you write H+r instead of r? Instead r just radius of planet, so we have to add H to r?
Hello, why does the law, linear quantity = angular quantity x r not apply for toruqe as then it would be F=TorquexR when it is really Torque=ForcexR? Thank you
may I ask where did you get the Value of -4.9t²?
Thank you for the explanation c:
May i ask why use negatice sign on gravity?
Gravity is always pulling us towards the center of the earth and that is the negative direction
Thank you thank you so much. I'm in a testing company and for so many years I was the grunt. This video course has helped me learn more about vectors using the calculator.
Glad this helped!
Thanks
6:55 how is 30 degree coming?
Nice video.
Super helpful and i love ur humor 💪
Ya
Since when is g=10
This video is for my AP Physics students and g=10 for problems on AP tests. It's a simplification that makes solving most problems a lot faster and your answer is generally very close to what you would get with 9.8 or 9.81. Hope this helps!
Do you know any good resources to self-study ap physics c mechanics? Or in general review for the ap exam?
Honestly the Princeton Review books are very helpful I think. They make a new one every year and are about $20 www.princetonreview.com/college-advice/ap-physics-c-exam ... They're not perfect and the questions won't be worded in the same way as actual AP test questions but the content review is very straightforward and helpful!
@@HowToPhysicsThank you! I will for sure check that out.
Hi, I noticed you didn't bring over the T after cancelling out the VoT (right before equaling everything to zero) was this in error? If intentional, can you explain the reasoning behind it? really enjoy your videos btw, you explain everything so much more clearly than my professor >_<
Great video very clear
Thank you!
Thank you so much!
Glad I could help!
Thanks!
I learn more in your videos than any of my physics lectures.😅 I’m surprised you don’t have a million subs already.
Thanks! I'm just a regular physics teacher so I don't put out much content, just what I make for my students. A million subs would be nice though!
