Chapter 17 Physics (static electricity)
def (process đã diễn ra)
electric charge + held | a charged insulator
example
lightning flashes
17.1 Charging and Discharging
electrostatic charge (lượng điện tích)
def (3)
-property of object + cause the repel/attract to other objects + with charge
2 types of charges
positive charge
electrical charge
17.2 : explain static electricity
Describe how it occurs (6) (nên nói detail electrons từ vật nào sang vật nào + biến charge thay đổi thành nega/posi)
-friction -> cause a force -> remove the electrons weakly held in atom -> electrons move from... -> static electricity occurs (thay đổi charge) -> results (repel/attract)
!required 2 materials to generate static electricity (1 nega + 1 posi)
Conductor vs Insulator
(electrical) Conductors
def (2)
A substance + allow flow of electrons move thru (electric current)
characteristics (metal)
delocalised electrons easy move -> can't stay charge + !only charged using Insulating handle (glove)
examples (3)
Copper, silver, gold, steel, metal
Insulator
def
Substance + inhibits the flow of electrons move thru (electric current)
examples (3)
plastic (polymer ~ perspex, polythene), glass, amber
Characteristic
electrons : tightly bound (held) + not easy move
17.3 Electric fields
def (3)
a region of space + where electric charge + experience a force
Needs to draw diagram (gg doc)
Negative -> arrow in; positive -> arrow out
