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 KZread TV with the Organic Chemistry Tutor.

I'm sure that you've read it alot of time, but, you are a life saver

we, students, are so thankful to have you!!! you explain so well!!!

I was hoping you would take it one step further and show example with non conservative force. But good summary though.

sir why did we take negative sign for Wc

Amazing video keep it up.

thank you. no one ever says applied is nonconservative, they just say friction which misleads me to think applied would be conservative without it.

Thank you so much .

very helpful..thanks!

Thank you!Sir!

hey nice video tHAnk u!

gotta love when your physics teacher essentially completely ignores this topic

My LIFE SAVER

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 are literally godsent.

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

hi ; is there a video when there is multiple forces acting on the system?

can nonconservative force be used interchangeably with external force?

Nice video 😃

Bhai sahab...thanks bhai

thanks

Thank you 😊

love your videos man, i live in south africa

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?

oh my god so helpful

How is the force applied in SHM conservative?

Thanks a lot. You remain the best

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.

11:00 why is the gravity (9,8) not negative here?

100th comment! you are so awesome! thank you!

But w = fs.. y r u considering distance instead of disp for friction?

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?

@rishikadhikari6326

2 жыл бұрын

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.

Hey you r great

Bro you rly be saving my ass, my teachers < you

I wish questions were harder because my course work is four times of this , not joking

you are the one and only wallahy

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

The explanation is good but Voice is low 😇👍

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

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?

@jedemmaludjecu2229

2 жыл бұрын

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.

@GodGurdjieff

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.
