Term
|
Definition
| A geometric waveform that oscillates (moves up, down or side-to-side) periodically, and is defined by the function y = sin x. In other words, it is an s-shaped, smooth wave that oscillates above and below zero. |
|
|
Term
| A moving wave that consists of oscillations occurring perpendicular (or right angled) to the direction of energy transfer. |

|
Term
| If a positively charged glass rod is used to charge a metal bar by induction, |

Term
| What is charging by contact? |
|
Definition
When a charged object touches another object.
Electrons can be transferred through friction.
Electrons can also be transferred through contact and conduction.
You can charge a neutral object by contact with a charged object.
Charging by contact happens when electrons move from one object to a neutral object.

|
|
Term
|
Definition
Charging by induction is an alternate charging method, which does not involve physical contact between to objects. Instead, this process involves bringing an object with a net electric charge sufficiently close to, but not in contact with, a second neutral object. As the charged object approaches, it causes an electric polarity within the neutral object. The type of polarity depends on the type of charge that is dominant in the charged object. Because like charges repel and unlike charges attract, if the charged object is negative, then the side of the neutral object nearest to the negatively charged object will become positively charged.
Require something like a conductor (ex. METAL) |
|
|
Term
| What is charging by polarization? |
|
Definition
Electrically polarized objects develop electric charges. There are at least superficial charges and in some cases volumetric charges. The sum of the total charge in the body is zero so there are positive
regions and negative regions.
Can occur with an insulator (ex. Wood) |
