What happens when two positive charges are brought close together?
They repel each other.
What happens when a positive and a negative charge are brought close together?
They attract each other.
What is electric charge?
A fundamental property of matter that can be positive or negative.
What is a Coulomb (C)?
The SI unit of electric charge.
What is an elementary charge (e)?
The magnitude of charge carried by a single proton or electron; approximately 1.6 x 10^-19 C.
Define a positive charge.
A type of electric charge carried by protons.
Define a negative charge.
A type of electric charge carried by electrons.
What are the differences between protons and electrons in terms of charge?
Protons: Positive charge (+1.6 x 10^-19 C or +1e) | Electrons: Negative charge (-1.6 x 10^-19 C or -1e)
Compare the interaction between like charges and opposite charges.
Like charges: Repel each other | Opposite charges: Attract each other
