What is Static charge?
Atoms become charged when the electrons move from one object to another
Explain electrostatics
The study of electric charge ( the why)
What kind of ways can you initiate a static charge? How do you lose or gain electrons?
By friction
Why are they static?
The charges are static because they remain fixed in one location on the surface of the object
T or F: An object that has more protons than electrons is positively charged
True
T or F: An object that has less protons than electrons is positively charged
False - more protons
T or F: An object that has more electrons than protons is positively charged
False - it is negatively charged
What is friction?
Transfer of electrons, gaining or losing electrons
Common ways of friction
Rubbing something together (balloons with hair, socks with carpet.)
What is the law of attraction?
When a negatively charged object is brought close to a positively charged object, the two objects attract each other. OPPOSITES ATTRACT
What is the law of repulsion?
When two objects with the same charge are brought together, they repel, SAME CHARGE = NO ATTRACTION
Positive objects have a…
Weak hold on electric charges
Negative objects have a…
Strong hold on electric charges
