|
Definition
| like charges repel and opposites charges attract |
|
|
Term
|
Definition
| the force between charged objects is |
|
|
Term
| electrical forces determined by |
|
Definition
| the size of the charges and the distance between charges |
|
|
Term
|
Definition
| a region around a charged particle |
|
|
Term
| although an atom contains charged particals |
|
Definition
| the atom it self doesn't have a charge |
|
|
Term
|
Definition
| equal number of protrons and electrons |
|
|
Term
| the positive and negative charges |
|
Definition
| cancel each other out and the atom has no overall charge |
|
|
Term
| the 3 comman ways for an object to become charged |
|
Definition
| frictian, conduction, and induction |
|
|
Term
| atoms don't stay charged they can |
|
Definition
| change their charge when they form an objects |
|

Definition
|
|
Term
| friction-2 objects rubbing together can cause |
|
Definition
| the electrons from 1 object to be on another. |
|
|
Term
|
Definition
| when electrons are transferred from one objects to another by direct contact. |
|
|
Term
|
Definition
| occurs when charges in an uncharged object are rearranged without direct contact |
|
|
Term
|
Definition
| when you charge objects by any method, no charges are created or destroyed |
|
|
Term
|
Definition
|
|
Term
| because electrons can move from atom to another the objects |
|
Definition
| objects have different charges |
|
|
Term
| if you were to count all electrons and protons after before and after charging |
|
Definition
| the number would be the same |
