Awesome way of teaching. I am also a proffesor of physics at iit indore college . But when i watching you in good manner of teaching , i am hopping that you are also a proffesor of physics. Thanks , i like your teaching manner.
Mam, I have question that If in 1st case is work done = -1148 and in second case work done = 1148 Does it mean the same work done??? As work is scalar quantity.... Please answer..... Confused a lot
Good question bro . Work has only magnitude and no direction All vector quantity can be negative but it doesn't mean some quantity with negative values are possible are always vector
Mam i have a doubt, in case of positive work frictional force also exists and in case of negative work frictional force still exists, so aren't they same?? Please reply ma'am 🙏
At case 1 it is force applied to body by hand in direction of displacement to be in motion whereas 2 force friction tries to oppose the motion or displacement so both are different cases of single example
If the angle b/w friction force and displacement is 180 (example when u slide a block then friction acts opp to displacement) nd is -ve ...if it makes a zero angle to displacement then the work is positive ( example: consider a two block system if the force is applied in the bottom block ftictiom will act opp to displacement so -ve work but for the upper block frictiom and displacement is in same direction hence +ve work)
(Mam please tell me) Savita is sitting on a chair and knitting a sweater (A) she is doing positive work (B) she is doing negative work (C) work done by her is zero (D) none of the above

Awesome Mam!! You killed it❤🤘
Ooo
Perfect.... understood completely... loved it ❤
Very well explained...🙌

ok but I doubt you're a professor given your sad attempts at trying to convey a message in human language.
Why are you boasting mate, I respect your aspirations to be a professor but please don't unravell the appellation of prestigious IIT'S
Examples are really important 💯💯💟
Yes
Mam as in positive work there is friction and also in negative work aren't they same
Mam, I have question that
If in 1st case is work done = -1148
and in second case work done = 1148
Does it mean the same work done???
As work is scalar quantity....
Please answer.....
Confused a lot
Yes
Mam but in trolley case the angle between force and displacement is not 0 but making some angle between them
Thanks mam very helpful ❤
Maam haw is this possible that in same condition two works apply. ( I mean +ve & - ve work____ I don't understand - ve work.)
Woh! Amazing, it's totally clear to me now. Thanks mam!!!
thanks a lot mam you cleared my concept in very less time keep it up .
Awesome😊😊👏👏👍👍
I'm totally confirm on this video
Sir I am Elton your big fan
Ok
Madam, I have a doubt. The work done can be negative or positive. Then why it is a scalar quantity?
Good question bro . Work has only magnitude and no direction
All vector quantity can be negative but it doesn't mean some quantity with negative values are possible are always vector
@@jyothilakshmik2699 absolutely correct
Thank u mam for the video 👌👌
This video is usefull for students
Awesome Mam Thankyou very much
Your examples is very IMP
Mam thank you so much 😍😍
Good explanation mam😍
Brilliant thx mam
That was great! thank you!
Mam ur teaching 👌
thank u mam for your auspicious knowledge
Friction force ke opposite kitna work hoga .in last concept
Super ma'am 🎉🎉 👌👌🏻👌🏼👌🏽👌🏾👌🏿😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁🙂🙂🙂🙂🙂🙂🙂🙂🙂🙂🙂🙂🙂
Excellent mam
Me who watching in class 11 to clear the topic 😂😂
I didn't understand that why work is 0 only when the body moves in a direction perpendicular to the direction of force. How can we say so?
Thank ma'am
And you look beautiful 😁😁😁
Excellent explanation mam
thank you po
👍👍
work is a scalar but some time we say their is negative work or positive work but how is it possible as we know work is a scalar ?
It was very helpful
❤
Nice vedio well for under stand 8ng
1. If an object is lifted there Is work.
2. If an object is lifted and is carried there is zero work.
Is this two statements correct?.pls respond
Soo helpful mam. thank Q...
Is potential energy a work done? As it makes 0° at y axis and 90°at x axis
Mam i have a doubt, in case of positive work frictional force also exists and in case of negative work frictional force still exists, so aren't they same??
Please reply ma'am 🙏
No. Because both forces are different
how?
At case 1 it is force applied to body by hand in direction of displacement to be in motion whereas 2 force friction tries to oppose the motion or displacement so both are different cases of single example
If the angle b/w friction force and displacement is 180 (example when u slide a block then friction acts opp to displacement) nd is -ve ...if it makes a zero angle to displacement then the work is positive ( example: consider a two block system if the force is applied in the bottom block ftictiom will act opp to displacement so -ve work but for the upper block frictiom and displacement is in same direction hence +ve work)
Thank you
Keep it up
(Mam please tell me)
Savita is sitting on a chair and knitting a sweater
(A) she is doing positive work
(B) she is doing negative work
(C) work done by her is zero
(D) none of the above
Zero work as no displacement
Zero WD
Thanks mam
👩🎓👩🎓👩🎓
💯
All doubt clear
Thank u mam ...
Thanks
Nice mam but you missed the concept of w= f * cos thita * s
Cos thita = 90° and cos 90 is equal to zero. So work done will be zero
Nice
Keep doing many videos
It's works 🤣🤣🤣no really its explain very nicely I m understand that
Pls explain cos
Yes
Super up u
But I had a hard time understanding the zreo work.
she explained wrong
@@jeopardyking7187 then what's the right?
more useful than my mom thanks
Wonderful
That make's no sense at all.
What makes no sense?
Hi
*The one she stares at me, it's creepy*
Well i gotta have to study this before its too late.
Sry mam i think you need to do more hardwork....
Not very good
Not nice but keep it up try hard
Superb mam TQ so much
Thanks mam
Nice 👌👌👌
Thnku so much mam
