i’m having to relearn all of physics before my AP test since my teacher didn’t actually teach us half of the content right, you’re a lifesaver oml thanks so much
The way you explain is very straightforward. Thanks for clearing up some hard-to-grasp concepts the day before the exam. I wish you did AP chemistry as well.
Just a small suggestion, perhaps explain why KE is not conserved in inelastic collisions because v is decreased and in the KE equation, v is squared so there's a bigger difference. (at least I think that's why) But besides that, everything is great! :)
Any chance you could help me out by doing what I ask people to do in the following video? bit.ly/2y4tOCA It would be a great way to show your appreciation!
Hey flipping my physics test went really well today! It covered stuff like conventional circuits , electrostatics, oscillations and of course older concepts intermingled within the free response questions like kinematics and energy with a problem invoking a spring
back at it again, might fail the test but you REALLY help, i swear. i didn’t fail my last energy test as badly as i thought i would, so truly thank you.
I think you need to add a very important note to the start of this nice video. Momentum is only conserved if the sum of all external impulses acting on the system is zero. Otherwise, it is not conserved. In the end of your video you use the second law to derive a relationship of change in momentum to impulse which clearly contradicts essentially your claim of conservation of momentum always being the case.
You are welcome! I am working to get review videos of every topic covered on the AP Physics 1 exam. Considering the short timeline until the AP Test in May, I don't think I will be able to do example problem videos. I do have all of my in-class lectures at flippingphysics.com/algebra.html They aren't quite as exciting as these videos, however, there are many example problems worked out.
@@FlippingPhysics AHH thank you sm, also can you make a video on 2 dimensional collisions if you havent already? I have a test soon and your videos are super helpful

Hey! I have a question concerning force-time graphs. How do you describe the motion of an object from the force-time graph? Let's say if force is constant, then lets say if force is decreasing, and last if fore is increasing, how do you determine how the object is moving? (speeding up, slowing down, constant,etc).
Net force equals mass times acceleration. Assuming the force in the force-time graph is net force, if you divide that net force by the mass of the object, the graph will be of acceleration as a function of time.
Thank you so much for the videos. My only problem is that the plural of momentum is momenta but that is greatly overshadowed by your excellent explanations. Thank you so much, I will probably do better on the exam because of your videos!
I have failed all my quizzes and tests and I’m really trying to flip the switch with momentum but the homework he gives is nothing like the test. It makes me cry.
Your comments make me sad. I am glad I am here to help and you are supplementing your learning with my videos. Can you talk to your teacher about this?
@@FlippingPhysics Ahh yes but no matter how much i study day and night and I almost always get a F on the quizes and tests. My physics teacher is really amazing! but whenever i think i grasp the concepts I do horrible. However, I recently took a test on momentum and finally managed to get a B on a test which is the second best grade Ive gotten on anything since september(Your video really helped with the test btw!) Its more so the conceptual questions that leave me stumped beacuse class is only 45 minutes and i originally came from a school where the classes were around an hour and a half giving me more time to think and grasp things as im not exactly the brightest crayon in the box. I rarely have time to get extra studying in because my lab partners practically do nothing and i have to do majority of the lab work which leaves me more stressed because i really do try with the class and ask the teacher questions but I get zilch out of it and still fail. The class makes me severely depressed 89% of the time.
Any chance you could help me out by doing what I ask people to do in the following video? bit.ly/2y4tOCA It would be a great way to show your appreciation!
An elastic collision is not possible on a macro scale. Non-atomic objects will always have some energy converted to heat during collision because they deform. That is one end of the "ideal extreme". The other end is a perfectly inelastic collision. This type of collision does occur on a macro scale and is not actually all that unusual.
4:41 Wow, the dedication you have is unmatched. Thank you for that.
Thank you so much for posting these!!! You're saving lives! (The lives of the juniors who are going to take the AP Physics exam)
catgoesmeow07 You are welcome. I thought I was only teaching physics, however, now I know I am saving lives! That's cool. :)
Flipping Physics this is true! Wish us luck tomorrow.
so how has ur life been since the AP Physics exam
And sophomores :(
The fourth in my set of AP Physics 1 review videos. Enjoy! #PhysicsED #flipclass #APPhysics1
You are an awesome teacher. My AP Exam is tomorrow and you taught me more in 5 min that I've learned in 4 months! Thank you! Keep making vids!!
you a real one for carrying me through this exam

I do AP Physics C: Mechanics....
i watched half of your ap physics 1 videos yesterday and the rest today and i remember so much stuff that i forgot about for the exam today
I really like physics but im so trash at it. If i get a 3+ on the test ill owe it all to you
I'll take it. Good luck!
AkZeNT same dude. I feel like the course really isn't an indicator of aptitude in physics. Also good luck tomorrow lol
howd you end up doing?
about to go fail ap physics 1!!!! woot!
Katie Cao omg me too
Blasphemy this was me last year before the ap and i passed the ap!! do not fear~
Katie Cao cool i have my sem 1 final tommoroe wish me luck!
Blasphemy good luck!!! :)
yus i passed my final with a 82

Thank you very much, I appreciate how concisely you teach as well as the humour you add to the lesson.
+Theforzarama You are welcome. Glad to know someone things there is some humor; I try.
+Flipping Physics Haha I just wish I would have found it with more than a day before the exam XD
+Theforzarama Share with your friends so they don't have to find it so late in the year, eh.
+Flipping Physics yes I shared it with my class, super great resource!
I FREAKING MANAGED TO PASS THE CLASS WITH AN 88.4CLOAS TO AN A YOURE VIDEOS HAVD HELPED ME SO MUCH
Congratulations!

Literally taking my AP Physics exam in 3 minutes, your videos help a LOT. Wish me luck lol.
+Lindsay Coleman Good luck! I know I missed getting it to you before you started. But know it's there!
back at it again, might fail the test but you REALLY help, i swear. i didn’t fail my last energy test as badly as i thought i would, so truly thank you.
You are certainly welcome. I hope you do not fail your next test
at 5:23 how is N*s = kg*m/s? Isn't N = kg*m/s^2? So wouldn't N*s = kg*m/s^3?
+WerewolfXD13 N*s = (kg*m/s^2) * s = kg*m*s/s^2 = kg*m/s

+Rachel Young You are absolutely welcome. Glad they are helpful in college too!
I have a question, at 3:12 if you multiply the top (vf-vi) by M shouldnt you do the same to the bottom (Time) ?
No, mass is only in the numerator. Mass is not in both the numerator and denominator.
For example:
2(x + 2) = 2x + 4
2(x + 2) ≠ (2x + 4)/2

I know I'm not perfect, however, I am glad I am helpful.
do u have examples of one dimensional collision problems using the law of conservation of momentum sir?
Yes, I do. Please check here: www.flippingphysics.com/algebra.html#momentum
thank you sir for all of your videos
You're boosting the national average of AP scores with these videos! Thank you so much! :)
Al3Industries That is my intent. I hope it works!

+Owen Young Interesting. When should I have said momenta?
Flipping Physics around the 52 second mark I believe
+Owen Young Yep. I say momentums don't I. I'll work on saying momenta instead. Never been so good with that English stuff. Physics good though.
Flipping Physics 100%! This video helped a lot for the exam!
Why is Bo always the last guy to show up? Is the door on his side?
Love these videos, they are really help, thank you very much!
+Ella Wan You are welcome. Thanks for the love!
You are great.Thanks again
Keep up the good work
Sir, what does momentum really mean? I don't want it to be explained as p=m•v.
Please help me!
Amazing helpful video
Can we talk about the fact that this man rode his bike off a dock in the name of teaching people physics. We stan.

Doesn't rho mean resistivity also?
Yes, rho also means resistivity.
4:40 is my favorite part, really helped me on the AP test. Actually love this guy tho
I loved doing it!
can you explain it , I don't exactly understand it
THIS IS FLIPPIN WICKED! ABSOLUTELY BONKERS MATE!
My physics teacher is very British, (Hi Dr. Hess!)
Lovely comment. Thanks!

what do you mean by they are the ideal extremes?

The other end is a perfectly inelastic collision. This type of collision does occur on a macro scale and is not actually all that unusual.

So
p=mv
Change in p = impulse = F times change in time
