hello everybody Welcome to vant telu channel this is your master teacher for physics k m are you all ready for vectors vectors lesson kumama are you all ready have we started hello everybody yes every live session attend very good girl Hello everybody FF gaming good evening FF gaming gaming student of C hello hello everybody Jessica love you dear yes Jessica happy e evening everybody Vector chapter weightage m one question it is not a separate chapter vect Vector vect basics sorry FF gaming okay so vectors Motion in a plane lesson sep vect Motion in first of all basics of vectors and types of vectors angle between vectors V so let us start with basics of vectors vector and Vector is this useful for it is useful for J also okay scalar okay total particles of the body mass into acceleration due to gravity so weight the gravitational force weight nothing but gravitational force force the vector quantity so speed mass time volume for example hour okay M please keep notes units and dimensions handwritten notes okay so scal of allal it has only magude no dire vectors both magnitude Direction a Madam for example a man is walking with a speed a man is walking with a speed with spe with a velocity velocity 5 m/ Second in East Direction East Direction 5 m per [Music] second East dire represent so magnitude and number only so magnitude number magit negative magnitude is always positive magnitude it is always positive magnitude always positive it can be positive or negative vect for example force is equal to 2 Newton force is equal to - 2on F1 F2 2us 2 magnitude same opposite direction magnitude same negative symb opposite direction SOI XIs so12 2 Newton 2 Newton magnitude same but Direction negative opposite direction represent so is that clear basics of scal vectors vect let us start with representation representation of vectors and magnitude length of Arrow length of Arrow magnitude represent head arent magnitude and the length of arrow for example let us take an example force is equal to F1 bar is equal to uh 2 Newtons IAP IAP meaning East Direction South in okay 2 Newtons in East Direction F2 bar is equal to 4 Newton same ection F3 baral 10 new in East Direction northest so e so1 direction arrow Mark length 4 Newton 2 Newton 4 Newton double length of the arrow 10 okay so so F1 bar F2 bar f one of the V bar s force Vector velocity Vector displacement Vector so vect f v magnitude only modulus of F Bar modulus of V bar modulus of SAR only magnitude only magnitude represent right South should be opposite of North oh sorry yes yes yes yes South North East okay Frankly Speaking anyways so Bas vect Vector representation next Vector types of vectors types of vectors first equal vectors oh equal vectors equal vectors magude and Direction vectors vectors with same same magnitude with the same magnitude and same direction same magnitude same direction and same physical quantities same physical quantities physical quantities anything that can be measured is called a physical quantity length mass time work volume density anything is called a physical quantity so so let us take if I take and equal vectors because magude Direction same and Q equ vitude equal vect because magnitude same and Direction same a bar and B Bar not equal vectors same direction but magnitude same next in P bar Q Bar magnitude same but Direction so equal vectors equal vectors vectors parall vectors vectors with same direction same dire Direction however however and however no need of same magnitude is difference same magnitude difference example example A Bar B Bar yes they are parall vectors A Bar B Bar parall vectors P bar Q Bar yes parall vectors P bar Q Bar parall vectors okay okay ma' magnitude and Direction yes vector quantity area is a vector quantity area is a vector quantity outward vect indic IND indicates area Vector direction is a vector quantity okay sry vect equ vect vect vect vectors anti parall vectors and same definition like parall vector parall vector vectors M the angle the angle between between the angle between two anti parallel vectors Uncle parallel vectors anti parallel vectors the angle between two anti- parallel vectors is 180° vectors parall vectors mle zero yes correct vectors yes Jessica vectal vect 18 B Bar anti parall vectors correct P bar Q Bar anti parall vectors magnitude technique problems when a vector when a vector is rotated when a vector is rotated through when a vector is rotated through 180° we get anti parallel Vector we get anti parallel Vector of that given vector vector 180 vector okay time is a scalar quantity asgar Al maths Academy time is a scalar quantity Academy hours so time is a scalar quantity anything till now if I start studying from now can I I get 450 Plus in IP ma'am ah crazy gamer IP no problem 450 so first of all a minus a a an Vector problem problems 7 or 7:30 regular time 7 or 7:30 vect delete anti Vector minus okay 18 vect anys zero Vector deleted clear zero vector and a vector with zero magnitude a vector with zero magnitude and any arbitrary Direction arbitrary any arbitrary Direction undefined simple English undefined English undefined Direction okay [Music] arbitrary undefined pleas please please 680 okay sir okay 680 okay yes no specific Direction polar vectors polar vectors and axial vectors polar vectors and axial vectors polar vectors axial vectors these vectors polar vectors these vectors produce these vectors produce linear motion body linear motion straight line motion straight vect these vectors produce these vectors produce rotatory effect rotat effect or motion rotatory effect or rotat motion vect straight sorry vect vect course Bridge Vector important course Bridge course [Music] Bridge anyway examples Force momentum Force momentum Force body examp torque torque angular momentum rot motion St soce vectors and axial vectors next Co vectors Co initial vectors Co important unit vectors important unit vectors a vector whosee is one defition a vector whose magnitude is equal to Unity Unity One For example let us take an example let us take an example if a bar is a unit Vector if a bar is a unit vector a vect mod value mod modulus of a bar value I already solved all PQ of vectors okay yes one already representation Vector representation unit Vector separate represent vectoral treatment so vector cap cap yes cap c cap a cap B cap I cap J vect treatment AAL a by modulus of a bar a cap is equal to a bar by modulus of a bar unit Vector formula formula of unit Vector vect example problem is done if a bar is a vector unit Vector is a unit vector I + 4 Jus 2 K Vector a equal to a bar by modul of please do how to solve problems in physics please do I will do a separate video an dedicated to you easy easy physics questions any okay any out of 40 questions 18 questions easy questions M out of 40 okay 18 questions easy Jessica something root 3 squ + 4 square + - 2 whole squ so under square uh 9 + 16 + 4 29 so AAL a 3 I + 4 J - 2 K by < tk29 problems 2025 yes 2025 2024 vectors ninja gamingid fluid solid fluid within two days already flid best yes an I don't I will not forget problem solving techniques oral orthogonal unit vectors orthogonal perpendicular orthogonal perpendicular so perpendicular unit vectors perpendicular unit vectors i j cap K cap orthogonal unit vectors I cap K J cap K cap which is along positive X Direction a vector which is along positive X Direction a vector which is along negative y direction negative y direction negative y direction k Sorry positive y direction K positive Z Direction I minus J cap minus K cap negative represent negative xais negative y AIS negative Z AIS so unit vectors unit vectors and modulus of I is equal to modulus of JC is equal to modulus of K cap is equal to 1 i j k they are unit vectors unit vectors magnitude equal mod of I one mod of J mod of K one easy simple method for example for example a car a car moving due east due east due east with 5 m per second velocity simp V equal 5 i m per second east north south west X Direction y direction minus X Direction minus Z Direction minus y direction okay so M 5 but dedicate your number of hours for practice an MA next next example a bus a man uh a man exerts a man exerts uh 10 Newton Force downwards downal 10 Newtons Direction downwards downwards negative Y axis negative y AIS minus jcap Newton so minus 10 jcap Newton for example take let us take S Bar is equal to Min - 5 K cap- me Z axis Direction displacement magnitude 5 m negative Z AIS okay problem solving techniques first problem solving technique the first and foremost important when a vector when a vector is moved when a vector is moved parallel to itself parall to itself then there is no change then there is no change in that vector let us take reference XIs yis par okay so a bar magnitude because very important problem solving next important point when a vector when a vector is Multiplied multiplied by a scalar vect of all magnitude and number right scal magnitude number okay soe when when a bar is Multiplied a bar is multiplied by a scalar Lambda l l number same direction Lambda lamb if a bar is Multiplied a bar is multiplied by minus Lambda so SI Direction Lambda a us Lambda 18 okay problems next most important angle between vectors angle between vectors rules rules between vectors if you want to measure angle between two vectors first point the two vectors the two vectors must be joined must be joined tail to tail tail to tail or Head to Head attach iali first number one point number two point smaller of the angle between smaller of the angle smaller of the angle between vectors must be considered must be considered the two vectors must be joined tail to tail or head to head so ta small smaller of the Ang are youting let us take some examples okay so it P bar next Q Bar p q angle me p q angle me can I just do correct am I corre option A correct option b wrong option C none of the above correct or wrong don't know at the vantu option C very good super B yes it is wrong is wrong head toil toil arrang this is wrong so head to small the and parall Vector of Q Vector then you can find angle noer vectus Q between pus Q have you understood I had a problem in listening in the class at vantu telu meana I had a problem first of all I have a problem but any okay take some example problems and solve if if a bar makes 30° makes an angle makes angle 30° with x-axis problems with x-axis B Bar makes an angle B Bar makes an angle 45° below xaxis c bar makes 60° below xaxis okay below xaxis question a question a find angle between a bar and B Bar question B find angle between a bar and C bar option uh question C find angle between and I have a doubt in R Optics what is the doubt you can put a message to me in inst or Whatsapp [Music] Okay Okay C X above or below but XIs right so a making an angle 30° with x axis next B Bar making an angle 45° below xais so e b bar 45° next c bar angle 60° below xaxis 45 60° color color what color I want green color green color okay very good start in the spamming confidence over confidence challenge confidence because okay so that is my answer to anyone because teaching Prof dation passion teaching [Music] expers [Music] okay last time not teaching last two years out of 25 questions 24 questions answer without a negative [Music] okay but yes thank you for your all your support guys thanks anyway so answer question 60 answer 90° B A sorry sorry sorry wait a a 30 + 45 30 + 45 75° next a 60- 45 60 minus 45 okay so 60- 45 6us 45 if a bar B Bar C bar represent a bar B Bar C bar represents sides of an equilateral triangle equilateral triangle sides of question same find the angle between a bar B Bar B Bar C Bar C bar a bar question question find angle between find angle between a bar and B Bar M next question B bar and C bar next question a bar and C bar a b c answer 60° between all of them between vectors head to head to head tail to tail to tail Arrangement B Bar head c bar tail c bar head a bar tail attach B tail C tail a bar tail C tail tail to tail attach between vectors 120° 120 120 so answer 120° not 60° it is 120° not 60° 2 months 50% you can crack otherwise I cannot give Assurance okay next problem different next problem a man walks along x-axis a man walks along x-axis with XIs East XIs East with 10 m second velocity 10 me second velocity a car goes with a car goes with 20 m/ second 20 m/ second and 30° 30° west of North sentence bestest of North next a bus goes with a bus goes with 60 m/ second by making an angle 60° with uh 60° with 60° sentence 60° west of South 60° west of south of all first of all East West directions draw East North West South ection X AIS so velocity of man 10 m second okay the velocity of man next 30° west of North West of North because 9:00 math class joined in Telugu batch but still it's totally my mistake ma'am reply please why do you feel like that Ravid why do you feel like that just because one subject teacher you don't like the entire physics coaching is waste I mean entire Dua coaching is waste vedantu.com ticket but you cannot say the entire vantu team is waste just because for example that is why I gave an answer but otherwise I can understand that otherwise my message to me in what way you are feeling it is waste Ravi na insta ID kapali radavi inest subject I have raised ticket you are going in a wrong track first of all R first of all you are going a wrong track prepar that is a wrong step beginning practice questions beginning practice questions April month for example Motion in a straight line motion a straight line Motion in a straight line mod okay first okay practice Ravid just message me I'll talk to you Ravid just message me in insta I'll talk to you okay now insta ID kapali RI k t t a k o t t a p a l l iali Rami confused maam please shall we do that open heart with open with so if anybody wants open heart but yes I trust you are a boy I guess user ID RAV k t p a l i kapali year second first first year second year okay shall we conduct a open class so that you can ask me doubts telam inam Cod please please please mail ID mail ID mail ID ma r m a d e v do s r gmail.com yes privacy privacy anyways question 20 me 30° West of car 30° velocity of car 20 m Dees west of South South West sou West WOC 60 I'm a girl my parents won't allow me to install install mail ID I gave ma ID ma me at least reply anyways between angle between uh man and bus velocity say man and bus velocity of man velocity of bus find out man bu 90° 0° car key angle between angle between velocity of car and velocity ofs find out problem new student you teaching is super thank you so much sumal keep following keep following AMA okay so problem thumbs up please one thumbs up Sprite thumbs up yes 9 Head to Head okay 90 super question correct very much correct but question taken in clockwise anticlockwise anticlockwise clockwise okay yes 90 + 60 150 yes but clockwise anticlockwise angle measured clockwise add subraction resolution of vectors vect multiplication of vector scalar product finish Ro doubt you can ask fast okay AMA Roa any doubt no am Al Roa you can ask your doubt I'm waiting for your doubt ganes n madam [Music] Roa doubt ask yes PDF Vector Yes pdfr Channel upload Center of mass harand work for energy of motion by everybody Publications are best for M ma'am yes best yes AMA okays l thank you sanj to Welcome to the class so shall we close the class J love you too dear holid [Music] ahead unab okay thank you lingti Shas thank you so much so R addition subtraction resolution projection of vectors happy okay so everybody celebrate safe
