Static electricity Flashcards
What will happen if two objects with the same charge are brought together?
Repel
What will happen if two objects with the opposite charge are brought together?
Attract
What is the overall charge of atoms and why?
Atoms are neutral as they have the same number of protons and electrons
How is static electricity produced?
By rubbing two insulators together
What is static electricity?
The build up of charge
Why is it called ‘ Static’ electricity?
Because the charge cant move
What happens when charge builds up on an insulator?
A potential difference is created, which can lead to a spark (a sudden movement of charge)
Which particles are transferred between surfaces?
Electrons
Which forces must act between two surface to transfer electronss?
Friction
Is static electricity a contact or non contact force?
Non-contact
What charge will an object have if it gains electrons?
Negative
What charge will an object have if it loses electrons?
Positive
In which group of materials does static electricity occur?
Insulators
What is meant by the term “electric field”
Area around a charged particle where other charged particles experience a force.
