What is the charge on a proton?
The charge on a proton is positive.
What is the charge on a neutron?
The charge on a neutron is neutral.
What is the charge on an electron?
The charge on an electron is negative.
What is a substance that allows the flow of an electrical current called?
A conductor allows the flow of electrical current.
Electric forces are ______________ between protons and electrons.
Electric forces are attractive between particles like protons and electrons.
When objects are further apart, the electric force _____________. (Increases or decreases?)
When objects are further apart, the electric force decreases.
What makes the difference between Conductors & Insulators ?
In conductors the charges move freely, and in the Insulators the charges cannot move freely.
Electric forces are _____________ between two like charges, for example protons and protons.
repellent
A proton's electric field is directed _____________ and an electrons electric field is directed _____________.
A proton's electric field is directed outward and an electrons electric field is directed inward.
What are the building blocks of matter that make up everything?
Atoms are the building blocks of matter.
Electric forces can occur over a distance (non-contact) due to what?
The space between electric forces is called electric field.
Why do insulators stop the flow of an electric current?
Insulators stop the flow of an electric current because their electrons are bound tightly to their atoms, not letting the charge through.
The energy of an object due to its position relative to another object.
Potential energy is the energy of an object due to its position relative to another object.
A circuit must be a _________ ___________ for the electric current to flow.
A circuit must be a closed loop for the electric current to flow.
As opposite charges get further apart, does potential energy increase or decrease?
As opposite charges get further apart, potential energy increases.
