Transformasies: nie in caps

In hierdie afdeling gaan jy leer oor die verandering wat die koördinate van ʼn punt ondergaan wanneer die punt horisontaal of vertikaal op die Cartesiese vlak skuif. Jy gaan ook leer wat met die koördinate van ʼn punt gebeur wanneer dit reflekteer word in die x -as, y -as en die lyn y = x .

Translasie van ʼn punt

Waneer ʼn voorwerp langs ʼn reguitlyn beweeg word, sê ons dit word getransleer . Wat gebeur met die koördinate van ʼn punt wat horisontaal of vertikaal getransleer word?

Bespreking : vertikale translasie van ʼn punt

Voltooi die tabel deur die koördinate van die punte soos op die figuur in te vul.

Punt x -koördinaat y -koördinaat
A
B
C
D
E
F
G

Wat let jy op omtrent die x -koördinate? Wat let jy op omtrent die y -koördinate? Wat sal gebeur met die koördinate van punt A indien dit verskuif word na die posisie van punt G?

Wanneer ʼn punt vertikaal op- of afgeskuif word op die Cartesiese vlak, bly die x -koördinaat van die punt dieselfde, maar die y -koördinaat verander met die aantal eenhede wat die punt op- of afgeskuif is.

Byvoorbeeld: in [link] word punt A 4 eenhede opwaarts geskuif na die posisie gemerk deur G. Die nuwe x -koördinaat van punt A is dieselfde ( x =1), maar die nuwe y -koördinaat het 4 eenhede geskuif in die positiewe y -rigting en word y =-2 +4 =2. Die nuwe koördinate van punt A is gevolglik G(1;2). Soortgelyk, vir punt B wat 5 eenhede afgeskuif word, bly die x -koördinaat dieselfde ( x = - 2 , 5 ), maar die y -koördinaat het 5 eenhede in die negatiewe y -rigting geskuif. Die nuwe y -koördinaat is dus y =2,5 -5 =-2,5.

Punt A het 4 eenhede opgeskuif tot by G. Punt B het 5 eenhede afgeskuif tot by H.
Wanneer ʼn punt opgeskuif word, word die nuwe y -koördinaat verkry deur die translasie eenhede by die ou y -koördinaat by te tel. Wanneer ʼn punt afgeskuif word, word die nuwe y -koördinaat verkry deur die translasie eenhede van die ou y -koördinaat af te trek.

Bespreking: horisontale translasie van ʼn punt

Voltooi die tabel deur al die koördinate wat in die figuur aangedui word, in te vul.

Punt x -koördinaat y --koördinaat

G

Wat let jy op omtrent die x -koördinate? Wat let jy op omtrent die y -koördinate?

Wat sal gebeur met die koördinate van punt A, as dit geskuif word na posisie G?

Wanneer ʼn punt horisontaal links of regs op die Cartesiese vlak verskuif word, bly die y -koördinaat van die punt dieselfde, maar die x -koördinaat verander met die aantal eenhede wat die punt links of regs geskuif word.

Byvoorbeeld, in [link] word punt A 4 eenhede regs geskuif na G. Die nuwe y -koördinaat van punt A is dieselfde ( y =1), maar die nuwe x -koördinaat is 4 eenhede in die positiewe x -rigting geskuif en word x =-2 +4 =2. Die nuwe koördinaat van punt A by G is dus (2;1). Soortgelyk, vir punt B wat 5 eenhede links geskuif word, bly die y -koördinaat dieselfde ( y = - 2 , 5 ), maar die x -koördinaat word 5 eenhede in die negatiewe x -rigting geskuif. Die nuwe x -koördinaat is dus x =2,5 -5 =-2,5. Die nuwe koördinate van punt B by H is dus (-2,5;1).

Punt A skuif 4 eenhede regs na posisie G. Punt B skuif 5 eenhede links na posisie H.
Wanneer ʼn punt regs geskuif word, word die nuwe x -koördinaat verkry deur die translasie-eenhede by die oorspronklike x -koördinaat by te tel. Wanneer ʼn punt na links geskuif word, word die nuwe x -koördinaat verkry deur die translasie-eenhede van die oorspronklike x -koördinaat af te trek.

Three charges q_{1}=+3\mu C, q_{2}=+6\mu C and q_{3}=+8\mu C are located at (2,0)m (0,0)m and (0,3) coordinates respectively. Find the magnitude and direction acted upon q_{2} by the two other charges.Draw the correct graphical illustration of the problem above showing the direction of all forces.
Kate Reply
To solve this problem, we need to first find the net force acting on charge q_{2}. The magnitude of the force exerted by q_{1} on q_{2} is given by F=\frac{kq_{1}q_{2}}{r^{2}} where k is the Coulomb constant, q_{1} and q_{2} are the charges of the particles, and r is the distance between them.

what is a capacitor?
Raymond Reply
Capacitor is a separation of opposite charges using an insulator of very small dimension between them. Capacitor is used for allowing an AC (alternating current) to pass while a DC (direct current) is blocked.

which has a higher temperature, 1cup of boiling water or 1teapot of boiling water which can transfer more heat 1cup of boiling water or 1 teapot of boiling water explain your . answer
Ramon Reply
I believe temperature being an intensive property does not change for any amount of boiling water whereas heat being an extensive property changes with amount/size of the system.
Someone
Scratch that
Someone
temperature for any amount of water to boil at ntp is 100⁰C (it is a state function and and intensive property) and it depends both will give same amount of heat because the surface available for heat transfer is greater in case of the kettle as well as the heat stored in it but if you talk.....
Someone
about the amount of heat stored in the system then in that case since the mass of water in the kettle is greater so more energy is required to raise the temperature b/c more molecules of water are present in the kettle
Someone

Two bodies attract each other electrically. Do they both have to be charged? Answer the same question if the bodies repel one another.
JALLAH Reply
No. According to Isac Newtons law. this two bodies maybe you and the wall beside you. Attracting depends on the mass och each body and distance between them.

Are you really asking if two bodies have to be charged to be influenced by Coulombs Law?
