100
yes
Is Static electricity an electric charge built up in one place
100
When the charged object (the body) loses its charge, the body becomes neutral once again. An electric discharge is the loss of static electricity as the electric charges move off the object.
The charge that develops may be released through a spark as the body goes near an uncharged or a positively charged object.
100
The occurrence of a natural electrical discharge of very short duration and high voltage between a cloud and the ground
What is lightning
200
"jumps"
The electrons need dry air in which to buildup and make their
200
static electricity
Positive and negative charges at rest on an object are called what?
200
a person rubs their shoes across a carpet in dry weather, the body builds up negative charges that are released from the carpet.
Normally a body is neutral since the number of electrons is almost equivalent to the number of protons
200
it can kill you
how can lightning harm you
300
Benjamin Franklin
showed that lightning is a form of static electricity
300
atom is said to have a positive charge
If there are more protons than electrons in the atom
300
It is the direct contact between two objects.
Conduction is another way that objects can become charged how
300
between 50,000 and 55,000°F
how hot is lightning
400
this caused the fibers on the string to stand on end
how the voltage differential between the clouds and the ground was sufficient to charge the string,
400
the atom has a negative charge
If there are more electrons than protons in the atom
400
When electrons are transferred between two objects that are rubbed together, the objects become charged due to friction
How can a object can become charged in several different ways
400
Wind starts to rub the surface of the ground and the buildings. Then, the molecules take electrons from them and carry them to the sky. The ground becomes positively charged and the bottom of the cloud becomes negative and upper part becomes positive
How is lightning started
500
high voltage
What is another word for static electricity
500
positively charged protons, neutral neutrons, and negatively charged electrons
Atoms are composed of what?
500
it stays in one place
If you rub only one end of a plastic comb, then only that end becomes charged does it stay in one place or move
500
The cloud has high potential than the surface of the ground. When the charges are strong enough to flow through the air (the insulator), then it takes the shortest course in the air that has a very low electric potential energy
