100 subs after 103 videos Mad respect for you brother!!!
hoorayyyy!!
i love u don’t die
congratsss
Congrats person who has the same name as me
love from North Korea (the northern part of north Korea where freedom exists)
Congrats dude
congrats!!!
🥳🥳
do calc bc content
Have my kids krishnna roa
Yo
W video bro congrats
yo why is this dude better at teaching than my professor 💀
love from Independent and Sovereign Republic of Kiribati
my thoughts exactly
nice
Love from india bro❤ keep it up
@@jitendradarji6214 thanks dude
Pretty cool
It's over for bro 💀💀
Good job
type shi
Good video 😊
Can u do a parallel version of this please
just landed in brooklyn
like ur videos bro, where u from? These lectures are for self-teaching or what?
@@l3vyl77 I’m from the united states, and I make these videos for my AP physics 2 class. I appreciate the kind words!! 👊
@@krishlikesscience your videos are really good, I literally watch'em just for fun. The content flows so clean, and give that student-to-student vibe, although you're a teacher. I'm Brazilian.
I think you may want to turn the gain up in post, i can barely hear the video.
@@dehiscence good suggestion, i think ill ask get a microphone too
first
Super splendid
I like this dude's way of teaching❤❤
Appreciate it!
@@krishlikesscience Can you please use a mic next video?
ur so cute I want u
I did not understand anything but the rap was good
Thanks Bro!!
GREAT!
Going back to the beginning I see.
Bro at 10:00 , this is a case of short circuit . Current after passing through first resistance wont pass through 2nd resistance as it got a new path which has no resistance ( a "shortcut" path to bypass the 2nd resistance) . This will create abnormally high current to flow through the circuit which will burst or catch fire . Ultimately making the circuit open Keep going bro .
Thank you for the explanation! I wasn’t entirely sure what was going on because that “loop” didn’t seem to obey Kirchhoff’s law. This explanation makes a lot of sense. I’m not an expert at this stuff, and I try to make these explanation videos to enrich my learning. So whenever I’m able to learn something new from it, it’s always a win
Maybe teach in a place with more light?
@@timaasdhom9703 Thank you for the feedback, I have to improve my lighting😓
@@krishlikesscience I have a couple of panel light things from covid, maybe those can help?
@@andyfitz2183 Haha it’s up to you! I would love to borrow and try those out. Thank you!!
Love these videos dude
good stuff nigga 👍
Sorry if i forgot to mention, but gravitational forces can be neglected in this problem!
Great video! I love a good kinematics problem
OMG KING POSTED
Cool video bro!!
Awesome video. Happy to see you sticking to it!
Keep going brother
@@Alessandro-mg9oh thanks bro
🤯🤯🤯
Very good job! This is not a trivial calculation, and most students make the mistake that it is simply -GMm/r.
Thanks!
if i’m lucky i can get a 3…
Don’t worry, you can still get a lot of points even if you don’t have the “right” answer! Also, multiple choice will help your score a lot too
@@krishlikesscience thank you, i hope so!
Was getting a little nervous watching this. I drew both the normal force and gravitational force for question 1, I just made the gravity larger than the normal force, which I didn't derive for to see the relationship, I just kinda drew it like that.
Usually those problems would say “draw each force with relative sizes” to indicate that you should draw the correct size for each force. Since the problem didn’t specifically say that, I doubt they were actually looking for that. As long as you drew both forces downward, you should be good!
@@krishlikesscience nice! Means I got 7/7 for this FRQ!
Momentum isn’t just conserved before and after the collision, it’s conserved during as well. Consider two systems A, B, with no external net force, F_A = - F_B dp_A/dt = -dp_B/dt dp_A/dt + dp_B/dt = 0 d(p_A + p_B)/dt = 0 p_A + p_B = const Also, when you are considering the bouncing ball, the wall does indeed have a change in momentum, momentum must be conserved! The issue is that the wall is connected to the ground, which is connected to the Earth, so, when the ball collides with the wall, the momentum of the entire earth changes, but the corresponding change in velocity is so infinitesimally small it is undetectable.
Thank you for your comment! You’re absolutely right, momentum is conserved throughout the entirety of the collision. In Physics 1, it’s useful to determine the momentum before and and momentum after a collision to figure out an unknown variable, which is why I emphasized that. But yes, momentum is conserved throughout the entire collision and your math supports that. Also yes, you are right, the Earth will experience a change in momentum when a ball bounces back. I wanted the system to be just the wall and ball in order to demonstrate that external forces will not allow the momentum of the wall-ball system to be conserved. For the whole wall-ball-Earth system, once again you are absolutely right that momentum will and should be conserved.
