For me, it has been "Chemistry 1 and 2", "Biology 1"(He doesn't really have anything on Biology 2 sadly), and now "Intro to Physics". I suspect he will be getting me through " Physics 1 and 2", "Precalculus", and "Calculus and Analytic Geometry" as well.
Professor Organic Chemistry Tutor, thank you for a basic Introduction/understanding of Conservative and Nonconservative Forces in Applied/Engineering Physics. The examples really test my knowledge of Conservative and Nonconservative Forces in old fashion Physics. This is an error free video/lecture on RUclips TV with the Organic Chemistry Tutor.
You ACTUALLY managed to clear my confusions! Thanks Organic Chemistry Tutor❤️ Jesus loves you!❤✝️Repent and God bless Matthew 8:20 "Foxes have dens and birds have nests, but the Son of Man has no place to lay his head"
I found the answer for the first question in a different way at pt A PE=mgh and KE=0 there fore (PE+KE)at pt A=(PE+KE)at pt B mg(100m)+o=mg(30m)+1/2mv^2 mg100m-mg30m=1/2mv^2 mg(100m-30m)=1/2mv^2 divide both sides by m g(70m)=1/2v^2 rearrange the equation square root (2g(70m))=v square root (1372)=v v=37.04 for all of u physics nerds watching this video
I was told today that a conservative force is always a radial force. That doesn't seem to be right, but I'm wondering if there is a way to classify if more than just that it's non-conservative if it pushes or pulls. Does anyone know of another way to classify conservative and non-conservative forces?
you could just say that gravity is conservative because the change in kinetical energy(speed) of the object will be the same at the end no matter where we throw it if the height is the same while with friction, the more time an object spends on the road the work will be higher. like you will step on more rocks that can interrupt your motion and slow you down if you dont go in the straight line
I like to consider a mountain climber.. if he leaves his hotel, climbs a mountain and then return to his hotel, the work he does against gravity is zero because his starting and ending height is the same. Pe = mgh - mgh = 0. His route up the mountain (hard or difficult) doesn't figure anywhere in the maths.
Isn’t the work done by the net force equals to the change of the mechanical energy, or equals to the change of kinetic energy and the weight potential energy?
I don't think we calculate the work done by net force. Work done by different forces are calculated. If they are added together they equal net work. And no matter what, net work always equals change in kinetic energy of the object. So basically, Net work = sum of work done by different forces acting on the object. But understand that Work by each force can be calculated as F*d*cos(theta) so not all forces acting on an object will do work on that object. Also, remember that when calculating work done by conservative force such as gravity, just use the height not the actual displacement because work done by conservative force is independent of the path covered. I hope this helps.
I'm just confused as to why the work done by the friction is greater in path 2 than in path 1. The work done depends on the displacement no? So even if path 2 has a longer distance it still has the same displacement from point A to B in both paths respectively. Wouldn't this cause the work done to be equal in both paths?
There is only one thing that bothers me, why change in potential energy is the negetive of work done by conservative force, and which force are we talking about here I mean the one that is doing the work or the one that is opposing it, like if I lift an object to a height h the work done by me should be positive but the work done by gravity is it the negetive of potential energy gained by object😢😢😢😢

You really dropped the mic on this one. The video ended and my jaw was hanging open, you explained this so well!
these videos singlehandedly got me through orgo 1 and now they're getting me through physics

This made me appreciate physics a little more. Thank you !
we, students, are so thankful to have you!!! you explain so well!!!
I'm sure that you've read it alot of time, but, you are a life saver
Really Good !! MAN, You deserves A Million of Hearts.
I have been confused by that topic for so many years thank you I finally understood it!
This is so good thank you. You make so it easy to learn

gotta love when your physics teacher essentially completely ignores this topic
You made it simple to understand, thank you very much
yo are such a life saver, you make everything easy.... stay blessed
Really, I was so surprised to get this way of explanations thanks🤗😍
Tryna study a whole module in one night😭
Greatest explanation ever!!!! On this topic.
You always make everything easy for me
in about 15 minutes I understood what my prof wasn't able to explain, or maybe just didn't want to, to trip us up on the exam.
I was hoping you would take it one step further and show example with non conservative force. But good summary though.
YOU. ARE. THE .BEST🥺🙏
wow thanks from spain!!!
Thank you for making Physics easier 💕
thank you so much, love from turkey...
This guy is a lifesaver
love your videos man, i live in south africa
Thank you
Marvelous Job sir!

why is the gravity (9,8) not negative here?
You are literally godsent.
Nice video 😃
my dad should be paying you for my education not my very useless profs THANK YOU SO MUCH
thank you. no one ever says applied is nonconservative, they just say friction which misleads me to think applied would be conservative without it.
Amazing video keep it up.
Thank you 😊
sir why did we take negative sign for Wc

Thank you!Sir!
thank you so much.
Pls do a video on a conservative systems in classical mechanics with solved examples
100th comment! you are so awesome! thank you!
I found the answer for the first question in a different way
at pt A PE=mgh and KE=0
there fore (PE+KE)at pt A=(PE+KE)at pt B
mg(100m)+o=mg(30m)+1/2mv^2
mg100m-mg30m=1/2mv^2
mg(100m-30m)=1/2mv^2 divide both sides by m
g(70m)=1/2v^2 rearrange the equation
square root (2g(70m))=v
square root (1372)=v
v=37.04

woah woah woah

can nonconservative force be used interchangeably with external force?

hey nice video tHAnk u!
Thanks a lot. You remain the best
hi ; is there a video when there is multiple forces acting on the system?
THANK YOUUU
issas very naiiss
Was super stressed from midterms and your comment made me laugh. Thank you!
I'm just confused as to why the work done by the friction is greater in path 2 than in path 1. The work done depends on the displacement no? So even if path 2 has a longer distance it still has the same displacement from point A to B in both paths respectively. Wouldn't this cause the work done to be equal in both paths?
But it has more friction mate. Friction is also an additive force in this case. It adds up and makes it a bit more than work done in path A
absolute right
watching this before my test
Tommorow I have one of the most important exams of my life and god knows i would have failed if not for you.
How is the force applied in SHM conservative?
oh my god so helpful
Is normal contact force conservative??
yes
Aighr so conservative force = class room to restroom
Non conservative force =restroom to class room
where r u getting all these equations ? are they given or some
The explanation is good but
Voice is low 😇👍
lovely.
If a body move in parallel path what it's dirction
Where are you from sir ji
You teaches good us
You doesn't Indian because you language speed is other country
But wouldn’t the work done by gravity in your first example be greater with the longer path? Since W=Fd, and the distance is longer?
Actually work=force(vector).distance(vector) or work=force.distance.cosx
The distance between the 2 points is the same,the road is different
Its not w=fd; its actually force × displacement, and displacement is same in both , regardless the distance covered🕊💟
the chenge of kinetical energy of the object will be the same so it doesnt matter
thanks
Hey you r great
But w = fs.. y r u considering distance instead of disp for friction?
thanks
what is formular for potential energy its mg(hi-hf) or mg(hf-hi)????
mbulelo phakathi second one
Final - initial

why the gravity at the end was positive?
it is more helpful
