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 UA-cam TV with the Organic Chemistry Tutor.
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?
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?
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.
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
Work done is zero doesn't mean that you didn't work, It may mean that what you did actually increased it's potential or kinetic energy in such a way that in order to attain equilibrium, that body again reversed the work or appended it's energy somehow.
how about thermal energy? I read on halliday page 217 it says Wnet = ΔEmec + ΔEth I am wondering that ΔEth = |Wnc| so does it mean Wnet = ΔEmec + Wnc thus ΔEmec = Wnc, Wnet = Wnc + Wnc Im confused
as you probably know the friction slows down the object. so the object would lose its energy which means that the work done on the object must be negative. kinetic energy tells the work that can be done by an object. he just wrote random numbers since he didnt calculate anything.

Thank you so much! Without a doupt, you're the best teacher I've ever had. you're the reason I passed all my exams
May GOD continue to bless you. You are just what we need.
You explain theories so well. I am visual learner, so your videos help a lot. I love your channel.

Nice to meet you! I'm an Indian (living in Mumbai) and we also study these topics in grade/class 11...

Tryna study a whole module in one night😭
This made me appreciate physics a little more. Thank you !
This is so good thank you. You make so it easy to learn
You made it simple to understand, thank you very much
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!
where would I be without this man?
I'M AN INDIAN STUDYING IN CLASS 9TH AND I'M SO MUCH GRATEFUL FOR YOUR VIDEO LECTURES..
A BIG THANK TO YOU!! ❤
we, students, are so thankful to have you!!! you explain so well!!!
Greatest explanation ever!!!! On this topic.
Really, I was so surprised to get this way of explanations thanks🤗😍
I was hoping you would take it one step further and show example with non conservative force. But good summary though.
I'm sure that you've read it alot of time, but, you are a life saver
You always make everything easy for me
yo are such a life saver, you make everything easy.... stay blessed
wow thanks from spain!!!
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.
gotta love when your physics teacher essentially completely ignores this topic
thank you. no one ever says applied is nonconservative, they just say friction which misleads me to think applied would be conservative without it.
sir why did we take negative sign for Wc
YOU. ARE. THE .BEST🥺🙏
This guy is a lifesaver
Thank you for making Physics easier 💕
You are literally godsent.
very helpful..thanks!

Marvelous Job sir!
can nonconservative force be used interchangeably with external force?

Pls do a video on a conservative systems in classical mechanics with solved examples

why is the gravity (9,8) not negative here?
Thanks a lot mann!!❤
hey nice video tHAnk u!
Thank you 😊
Bhai sahab...thanks bhai
100th comment! you are so awesome! thank you!
hi ; is there a video when there is multiple forces acting on the system?
oh my god so helpful
watching this before my test
my dad should be paying you for my education not my very useless profs THANK YOU SO MUCH
thanks
If a body move in parallel path what it's dirction
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
Thanks a lot. You remain the best
what is formular for potential energy its mg(hi-hf) or mg(hf-hi)????
mbulelo phakathi second one
Final - initial
Aighr so conservative force = class room to restroom
Non conservative force =restroom to class room
Bro you rly be saving my ass, my teachers < you
you are the one and only wallahy
absolute right
why the gravity at the end was positive?
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
Nice☺
But I have a question if F=(1/x)i is a conservative force then why work done in this case=0
Did I do here wrong calculation? pls reply...
Your question was not clear, but work done can be zero.
Work done is zero doesn't mean that you didn't work,
It may mean that what you did actually increased it's potential or kinetic energy in such a way that in order to attain equilibrium, that body again reversed the work or appended it's energy somehow.
@@GodGurdjieff congrats I have understood better
THANK YOUUU
lovely.
Hey you r great
Is normal contact force conservative??
yes
u must teach universities how to teach
I wish questions were harder because my course work is four times of this , not joking
But w = fs.. y r u considering distance instead of disp for friction?
How is the force applied in SHM conservative?
Where are you from sir ji
You teaches good us
You doesn't Indian because you language speed is other country
how about thermal energy? I read on halliday page 217 it says
Wnet = ΔEmec + ΔEth
I am wondering that ΔEth = |Wnc| so does it mean
Wnet = ΔEmec + Wnc
thus ΔEmec = Wnc,
Wnet = Wnc + Wnc
Im confused
Legend
The explanation is good but
Voice is low 😇👍
where r u getting all these equations ? are they given or some
Ryt
Can anyone please tell me how the workdone by friction is _300?
as you probably know the friction slows down the object. so the object would lose its energy which means that the work done on the object must be negative. kinetic energy tells the work that can be done by an object. he just wrote random numbers since he didnt calculate anything.
