sir i have a question how direction of acceleration is in the direction of velocity when a body is decelerating then its acceleration direction is opposite to velocity so how it have same direction
@@ubaid1996 lol... Ball is moving in circle because you are applying two sets of forces.... One is in the direction of the motion and other perpendicular to motion... The force that is in in the direction of motion cause the ball to move forward and the other that Is perpendicular to the motion is keeping the ball in a circular motion by pulling it inward
Speed depends on distance and velocity depends on displacement. Distance and displacement are scalar and vector respectively. So we can say velocity has direction involved in it but speed does not depend on direction. Secondly , Precision means how close some values are from each other. While accuracy means how close these values are from mean.

Thank you so much ❤❤❤🤲
Mashallah Allah AP ko mazeed kamyabi day
Aameen
sir aap ka parhane ka method boht acha hai sab clear ho gaya masha ALLAH
My chapt 5 clear due to your lectures Thanku sir.keep working
Sir yai video aj daikhee mai ny ap ki last mai smile mashallah.❤❤❤
Just bcz of u
I solved this equation for the first time thank u sir ❤️
Kamal hu sir ap👏👏👏👏
Superb way of teaching ❤
Your teaching method is so much better
You are really great 🥰😝your teaching method is amazing🥰🥰🥰🥰🥰🥰🥰🥰🥰
Well explained 👏👏
Sir ap boht acha prhaty he bht bht bht... Allah tala apko jzay khyr dy ameen
Thank you🙏💕
Sir ap kamal hain itna acha samjhaya hai!
Excellent explaintion👌👌 sir ji
sr ap ka lecture boht informative ha
God bless u sir💜
Thanks for the vid
Thanks 😊 sir you are really very good teacher my concepts are really clear
sir good work
Sir you are a splendid teacher!
kamal sir
❤❤❤ legend of physics
nice sir thanks sir
Amazing sir. Thank u🤗
Sir Weldon very Weldon god bless you
Amazing lecture thnk u so much sir
Impressive method,,
Sir plz upload more videos of first year physics
weldone sir your teaching method so nice 👌
Excellent sir... Mazaa aaagya
Thanks a lot sir🤗🤗
bahot acha samjhaya ap ne ye topic. thank u
Nice method of teaching
Thanks so much sir☺️💕
Great👍
Jazakallah Sir!!!
❤
Very good sir it is help full . thanks 😊
Great!
Allah ap ka mukam-o-mrtba bulnd kry ameen
Sir hm papers mn agr sirf methametically form likh dyn or theory km likhyn to marks mil jayn gy???
Chas agii lecture dii mza agya
Amazing lecture
Great sir
great. keep it up
So good
Thank you sir g
Well done
Good 👍
Very good explanation
good work sir
this channel become useful for me
Sir plz make video on vectorial and unit form of angular displacement ,velocity and acc
Informative lecture
Thank you ❣️
Share our videos with your friends
Love you sir you a great
Only one thing ask
Why the perpendicular force does not change speed
Mashullah zbr10
Great sir.🙌
I like your lectures
Love u sir you inspired me from physics i hate always physics but now i found u so i love it tnx sir
sir i have a question how direction of acceleration is in the direction of velocity when a body is decelerating then its acceleration direction is opposite to velocity so how it have same direction
I have the same question if the velocity is decreasing then acceleration will have opposite direction to the direction of velocity
in this scenario it's not decelerating.. It's accelerating
@@mewying5184 no it's decelerating bcoz force is applied in direction opposite to the direction of motion
@@ubaid1996 lol... Ball is moving in circle because you are applying two sets of forces.... One is in the direction of the motion and other perpendicular to motion... The force that is in in the direction of motion cause the ball to move forward and the other that Is perpendicular to the motion is keeping the ball in a circular motion by pulling it inward
@@mewying5184 I m not asking about the rotation of stone in circle I m asking about the motion of car
Nice sir👍
Thank you ❤️

Thanks sir for this video i get a great information from it
Thank you share our videos with your fellows ❤️
Nice
Fantastic☺
JazakAllah
Sir in topic 5.11 why apperant weight is less than actual weight
Thanks 😊💕👍
Thanks sir
Great
Very nice 👍
Thank you 👍
Thank you so much sir
Sir if i solve it according to how you've done it in this video, will i get full marks for it
In your THUMNAIL there was a mistake
Sir jazakallah ❤️.. For this video 💜
Thank you for watching ❤️
Really nice lecture
Thank you share our videos with your fellows ❤️
Nice Sir👌😙
Excellent

Velocity change concept clear
Kmall
Nice lecture
Amazing sir
sir give us guess of physics for 1st year according to smart syllabus
Sooooooooooo sooooooooooo Good lecture
Sir amazing lecture
Ama dear sr,sr F=mv/r me force and radius are inversly proportional but in F=mrw force and radius directly proportional to each other.why
Thanks sir g
Nice sir
very nice teacher
Thank you very much
Sir what is the differene between precision and accuracy and differene of speed and velocity
Speed depends on distance and velocity depends on displacement.
Distance and displacement are scalar and vector respectively.
So we can say velocity has direction involved in it but speed does not depend on direction.
Secondly , Precision means how close some values are from each other. While accuracy means how close these values are from mean.
Sir you awsommmmmmmmm
Centrepetal force kitny time velocity k equal hoti h?? Mean k angular velocity kitny time increase hoti h?? Three time or two time??
sir ye vectors tho head to head parhe hai😕..tho head to tail rule kaise apply huwa?
sir from which country
Nice 🥰🥰
God bless u sirrrr
Superrb
So nice
👍👍👍
