Electric Fields Flashcards
what is an electric field created around
an electrically charged object
what happens the closer you get to an object that has an electric field
the stronger the field you feel
what do you use to show the electric field around an object when drawing
field lines
what do the electric field lines go from
positive to negative
how must field lines always be drawn in relation to the object
they must be at a right angle to the surface
what do field lines that are closer together indicate
a stronger field
regarding a spherical shape, how do the field lines represent its electric field well
because the further away from the object you go, the further apart the field lines are from each other which correctly indicates a weaker field
what does a charged object that is placed in the electric field of another object feel
a force
what does the force result in
an attraction or repulsion
why do charged objects attract or repel
because their electric fields are interacting with each other
what is the force of an object linked to
the strength of the electric field it is in
what happens when you increase the distance between the charged objects
the strength of the field decreases and the force between them gets smaller
explain how two oppositely charged particles react
- electric field of one interacts with the electric field of the other
- causes forces to act on both of them
- these forces move them closer together
when is a spark caused
when there is high enough potential difference between a charged object and the earth
what does a high potential difference cause, in terms of electric fields
a strong electric field between the charged object and the earthed object
