Physics Vocabulary
| Term | Definition |
|---|---|
| Electric Field Lines | Lines that indicate the path that a charged particle moves in when it is placed in an electric field. |
| Electric Potential | The electric potential at any point in an electric field is the work required to bring one coulomb of positive charge from infinity to that point: V = W/q. |
| Electric Charge | The positive or negative charge on an object |
| Induction | The process of redistributing charges on another body by attracting or repelling electrons. |
| Conservation Of Charge | If several conductors meet at a junction point, the algebraic sum of all the currents entering is equal to the sum of the currents leaving the junction (Kirchoff’s Law). |
| Electron | A small, negatively charged particle found outside the nucleus of an atom. |
| Volt (V) | The SI unit of electric potential or potential difference. |
| Static Electricity | Refers to electrical charges at rest; that is, when the net flow of charge in any given direction is zero. |
| Elementary Charge | Any charge is made up of integral multiples of a minimum charge called the elementary charge. |
| Static Charge | The “electrical” charge on an object due to the loss or gain of electrons. |
| Electroscope | A simple device in which a metal electrode is attached to two hanging pieces of metal foil and placed inside a glass container with the top of the electrode exposed at the top of the container. |
| Coulomb (C) | The SI unit of charge, approximately 6.3 × 1018 elementary charges (from the List of Physical Constants in the reference information). |
| Grounding | The addition or removal of electrons to or from an object in order to neutralize its charge. |
| Net Charge | The algebraic sum of the positive and negative charges in a system. |
| Electric Field | An electric field is said to exist in any region of space in which an electric force acts on a charge. |
| Electric Charge | The positive or negative charge on an object |
| Electron | A small, negatively charged particle found outside the nucleus of an atom. |
| Coulomb's Law | The electrical force between two point charges is directly proportional to the product of the charges, and inversely proportional to the square of the distance between them. |
