Two objects that have opposite charges will...
attract
repel
remain stationary
accelerate away from each other
Two objects that have the same charges will...
attract
repel
remain stationary

Induction
Convection
If you rub a glass rod with a piece of silk, the rod becomes positively charged. This means that
Friction destroyed electrons in the rod.
The silk has accepted electrons from the glass and is now negatively charged
Protons have moved to the rod.
The glass rod has accepted positive charges from the silk and is now positively charged
What charge does a proton have?
negative (-)
positive (+)
neutral
no charge
What charge does an electron have?
negative (-)
positive (+)
neutral
no charge
An electric field is
an open area of land where lightning strikes
the region around an electric charge where a point positive charge experiences a force
the region around a black hole where objects are sucked in
the region around an electric charge where a point positive charge experiences a force
Which diagram shows attraction?
Electric Fields are represented by
arrows
lines
dots
empty circles
PICK TWO ANSWERS: The number of neutrons in the atom can affect the
charge of the atom
the mass of the atom
the type of element
the stability of the atom
Conductors
inhibit the flow of electrons
impede the flow of electrons
allow the flow of electrons
resist the flow of electrons
Insulators
inhibit the flow of electrons
encourage the flow of electrons
limit the flow of a few electrons
allow electrons to flow only when a battery is connected
The diagram above shows the steps involved in order to
Positively charge a conductor by friction
Positively charge a conductor by contact
Positively charge a conductor by conduction
Positively charge a conductor by induction
Step (c) demonstrates
Electrons travelling up the ground connection
Electrons travelling down the ground connection due to repulsion
Electrons being attracted to the positive charges in the sphere and moving up from ground to pair up
Induced negative static charge on the wire
