QuestionAnswer
An area surrounding a charged object where another charged object experiences an electric forceElectric Field
What is an electric field?An electric field is a region around a charged object where another charged object placed in the field experiences an electric force.
Objects that have an excess or deficit of electrons, resulting in a net positive or negative charge.Charged Objects
What creates electric fields?Charged objects create electric fields around themselves.
The force exerted between two charged objects due to their electric charges.Electric Force
What does an electric charge experience in an electric field?In an electric field, an electric charge experiences an electric force.
The intensity or magnitude of an electric field at a specific point.Field Strength
How does field strength vary in an electric field?Field strength is strongest near the charged object and decreases as one moves further away.
Forces that can act on objects without physical contact between them.Non-Contact Forces
How does the concept of electric fields explain non-contact forces?Electric fields help explain non-contact forces by illustrating how charged objects can exert forces on each other without direct physical interaction.
The degree of force experienced by a charged object in an electric field.Electric Field Intensity
What determines the strength of the force experienced by a charged object in an electric field?The electric field intensity, or strength, determines the force experienced by a charged object.
The mutual influence or effect that charged objects have on each other.Interaction of Charges
How do charged objects interact with each other in an electric field?Charged objects interact by exerting forces on each other within the electric field.
The visual depiction of an electric field using arrows to indicate the direction and strength of the field.Electric Field Representation
How are electric field patterns represented?Electric field patterns are represented using arrows.
The effect a charged object has on the space surrounding it, creating an electric field.Charged Object Influence
What creates an electric field around a charged object?A charged object creates an electric field around itself.
The direction in which arrows in an electric field point, indicating the path of the electric force.Arrow Direction in Electric Fields
In an electric field, which way do arrows point in relation to charged objects?Arrows point away from positively charged objects and towards negatively charged objects in an electric field.
The direction in which the force acts on a positively charged object in an electric field.Force Direction on Positive Charge
How does the direction of arrows in an electric field relate to the force on a positive charge?Arrows in an electric field show the direction of the force that would act on a positively charged object.
The intensity or magnitude of an electric field at a particular point.Electric Field Strength
What do closely spaced arrows in an electric field pattern indicate?Closely spaced arrows indicate a stronger electric field at that point.
The skill of representing electric field configurations using arrows on a diagram.Drawing Electric Field Patterns
How can electric field patterns be drawn?Electric field patterns can be drawn by placing arrows to indicate the direction and strength of the electric field.
The electric field formed between two flat, charged plates.Electric Field Between Parallel Plates
How are electric field lines between parallel plates oriented?Electric field lines between parallel plates are parallel to each other, forming a uniform field.
The production of sparks, visible discharges of electricity, between a charged object and a conductor due to a high potential difference.Sparking
What causes sparking between a charged object and a conductor?Sparks are produced when there is a high potential difference between a charged object and a conductor.
The voltage or electrical potential difference between two points, indicating the energy per unit charge.Potential Difference
What is the role of potential difference in sparking?Sparks occur when there is a high enough potential difference between a charged object and a conductor.
The intensity or magnitude of the electric field at a particular point.Electric Field Strength
What produces a strong electric field between a charged object and a conductor?A high potential difference between a charged object and a conductor produces a strong electric field.
Removing electrons from atoms or molecules, leading to the ionization of air particles.Stripping Electrons
How does a strong electric field affect air particles?A strong electric field can strip electrons from air particles.
The ability of air to conduct electricity, influenced by the presence of free electrons.Conductivity of Air
Why does air become more conductive in the presence of a strong electric field?Air becomes more conductive when it loses electrons in the presence of a strong electric field.
The movement of electric charge (electrons) through air, resulting in a visible spark.Current Flow Through Air
What is the visible effect of current flowing through air in the presence of a spark?The visible effect is the occurrence of a spark, indicating the flow of current through the air.
Air normally acts as an insulator, resisting the flow of electric current.Air as an Insulator
What is the usual role of air in terms of electrical conductivity?Air is usually an insulator, resisting the flow of electric current.

What is an electric field?An electric field is a region surrounding a charged object where another charged object experiences a force.
An object that possesses an imbalance of positive or negative electric charge.Charged Object
What defines a charged object?A charged object possesses an imbalance of positive or negative electric charge.
Physical phenomena resulting from stationary electric charges and their interactions.Electrostatic Phenomena
What are electrostatic phenomena?Electrostatic phenomena are physical phenomena resulting from stationary electric charges and their interactions.
