Force is a push or pull. Force tends to produce motion. Force tends to stop a moving object. For example, when you throw a ball, motion produces in the ball. So exert force. Energy is the ability of an object/person to do some sort of work. For example, when you throw a ball you exert force due to which ball covers some distance. So you have energy to throw a ball. Force is a vector quantity. Energy is a scalar quantity. Thanks!!! 😊😊😊😊 Force is a vector quantity.
how work done is scalar quantity, while work done is product of force and displacement and they both have direction and both are vector quantities. so then why work done is scalar quantity. Please solve this confusion.
If we can recall the lesson about vector. Work is the dot product of two vector quantities force and displacement. The dot product always gives a scalar quantity. Therefore work is also a scalar quantity.
@@NAJAMACADEMYAsslam o alaikum sir 😢but now I am on right channel Thank you so much sir your Vedios are wonderful full of concept now I have applied for forces and your Vedios are very for my academic test😊 I hope I Will clear my test with good percentage
If we push any object and there is no movement, which means displacement is zero, in that case work done is zero. But what will be transfer of energy in this case?
Outstanding Question! 👏👏👏 Well, brother work is always equal to energy. OR. You can say that work and enrgy are the two sides of same coins. Now, when you exert force on an object and it doesn't move. So work done is zero. What about energy? The answer is simple... Transfer of energy is also zero. But this is purely an ideal case. (In real life, when you exert some sort of force on a body, you tranafer some sort of energy to that object. For example, Heat Energy. But it is so small amount that you can't detect it or you can say that it is negligible.) I hope it will clear the concept... Thanks
Bhaii apki energy transfer nahi hoo Rahi h ,apki energy tab transfer hoti ,tab vo object movement karta ,uss time p apki energy kinetic energy m transfer hoo jati
Yes Mam/Sir... According to Physics, we all are matters (Objects occupy some space and has mass) and energy ( having ability to do some sort of work)... Really sorry if you are not agree. (Just for fun) Thanks!!!😊😊😊😊
6:16 sir when force and displacement are in different direction work done need not be equal to zero When force and displacement are perpendicular to each other then work done is zero But your teaching is amazing keep it up
During walking the negative work done by external frictional forces is small, the negative external work done by the muscular force during each step practically equals the external positive work done.
ا لسلام عليكم
You clear my concepts Shukran my brother
السلام عليكم ✅

walaikumasalam bro
Sir I'm 8th class student this is amazing video for me
Thank you so much!!!
I have one doubt sir,without force we can't do work. So,how force is getting different from energy.
Force is a push or pull.
Force tends to produce motion.
Force tends to stop a moving object.
For example, when you throw a ball, motion produces in the ball. So exert force.
Energy is the ability of an object/person to do some sort of work.
For example, when you throw a ball you exert force due to which ball covers some distance.
So you have energy to throw a ball.
Force is a vector quantity.
Energy is a scalar quantity.
Thanks!!!

I wish if I could go back to FCS again 😐 because in FSC I wasn't having a MBL and I couldn't understand these things like this 😐
Same is my case...

Thank you sir i understand i have exams soon and im grade 8
Thanks sir u cleared my doubts I am student of class 9th thanks soo much ..😊😊
U r from which place
I am in 11 sci .Its really good explaintion
But displacement symbol is s

Work done = Energy
I didn't understand the example 5:51 minutes
how is work done=0
As cos 90° is = 0 , the whole term I mean 50N.30m (0) = 0
work is 0

Thank you very much sir 🙏💕
Are we (humans) objects?
Yes Mam/Sir...

Sir you are the best
Very great explanation
wowwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww awsomeeeeeeee
👌👌👌👌👌
Sir your explanation is over standing.
Plz upload videos related to numericals of work.class-11th.
Great explenation
Nice explanation sir Thank you
Because of forces are push or pull

Is walking affected by work?
During walking the negative work done by external frictional forces is small, the negative external work done by the muscular force during each step practically equals the external positive work done.
Nice
Very

Werden?? What the hell is that? I cant understand what you’re saying.
