GR9 NW OPSOMMINGS
KWARTAAL 4 2022


‘n Krag is ‘n trek of stoot.
 Uitwerking van ‘n krag:
-Beweging
-Vervorming
-Rotering
-Verander van rigting
-Bring voorwerp tot stilstand
 Voorwerpe oefen kragte op mekaar uit in pare.
Die kragte:
-is ewe groot,
-werk in teenoorgestelde rigtings,
-werk gelyktydig op twee verskillende voorwerpe in
 Kragte tree altyd in pare op.
 Soorte kragte:
KRAGTE
Nie-kontakkragte of veldkragte: Kontakkragte:
Werk oor ‘n afstand Voorwerp raak aan ander
voorwerp
Voorbeelde: Voorbeelde:
1. Gravitasie- 1. Meganiese kragte
aantrekkingskrag 2. Drukkrag
2. Magnetise kragte 3. Wrywingskrag
3. Elektrostatiese kragte 4. Normaalkrag
5. Veerkrag

 Krag word in newton (N) gemeet.
 Verskil tussen massa en gewig:

konstant.
EENHEID kg Newton(N)

,  Om gewig te bereken:




 Stowwe wat deur ‘n magnet aangetrek word, word
ferromagnetiese stowwe genome.
 Daar is twee soorte elektriese ladings:
-Positiewe lading
-Negatiewe lading




 Weerlig:
-Deeltjies en druppels in wolke skuur en stamp teen mekaar en
word gelaai.
-Groot hoeveelhede positiewe en negatiewe ladings word geskei.
-Negatiewe ladings hoop in laer helfte van wolk op; positiewe
ladings in boonste helfte.
-Geskeide ladings veroorsaak potensiële energie.
 Weerlig ontlaai ‘n grooy hoeveelheid lading aan die aarde wat ‘n
groot oordrag van energie vanaf die wolk na die aarde
veroorsaak.


 ‘n Sel is ‘n bron van energie.
 ‘n Sel bestaan uit:
-‘n Elektroliet (positiewe en negatiewe lone)
-Metaalstafie wat as pole/elektrodes dien
 Elektroliet: Oplossing wat elektrisiteit gelei.
 Energie in elektroliet: chemiese energie -> elektriese energie
 ‘n Battery is twee of meer selle wat in serie geskakel is.
