(17 cards)
What two types of charge can a material have
Positive and negative
What does neural mean when referring to charge
Having no charge
What happens to identical charges when they are close to each other
They repel
What happens to opposite charges when they are close to each other
They attract
What subatomic particle moves between materials to create static electricity
Electrons
What is the charge of an electron
-1
What force moves electrons between two materials
Friction
If a substance has become positively charged, what has happened to the number of electrons it has
It has lost electrons
If a substance has become negatively charged, what has happened to the number of electrons it has
It has gained electrons
What objects have an electric field
Objects with charge
What is the name of a force between charged objects
Electrostatic force
Is electrostatic force a contact of non- contact force
Non-contact force
What is the relationship between the strength of the electrostatic force and the distance from the charged object
As the distance increases, the electrostatic force decreases
Do we use to show the direction of an electric field in a diagram
Field lines
In which direction do the electric field lines point
From positive to negative
How is the distance between the electric field lines linked to the strength of the electric field
The closer the lines, the stronger the electric field
How is the force felt by a charged object related to the strength of the electric field
The stronger the electric field, the greater the force felt
