Definition
transfer of electrons from one object to another by rubbing
simplest and most fundamental electrification |
|
|
Term

Definition
| occurs when two objects touch, permitting electrons to move |

1. repulsion attraction
2. inverse square law/ Coloumbs law
3. distribution
4. movement
5. concentration |

Term
|
Definition
charges reside on the external surfaces of conductors
the result of the effects of repulsion attraction law as electrons attempt to repel eachother as much as possible |
|

Term
|
Definition
only negative charges move along solid conductors
the protons are tightly bound inside the atomic nuclei which dont drift in solid conductors |

Term
|
Definition
greatest concentration of charge is on the surface where curvature is greatest
electric charges tend to concentrate in region of sharpest curvature |
|

Term
|
Definition
when two oppositely charged objects are in close proximity, electrons often jump the gap
occurs as soon as difference in charges becomes sufficiently great and the intervening distance sufficiently small
releases energy in form of light photons and audible sound |
