How do two objects become charged through friction

One gains electrons and the other loses electrons

When objects are charged with friction one object loses electrons and becomes___ while the other gains electrons and becomes ___

Positively charged, Negatively Charged

Because objects charged through friction are opposite charges the two objects will___

attract

An object that charges another object through direct contact and the movement of electrons is known as _____

Conduction

An object that charges another object without contact, where no electrons are moved but charges are moved within the object, is known as______

Induction

How do two objects become charged through conduction.

A charged object touches a neutral object.

How do Objects become charged through induction.

a charged object is a neutral object.

what does it mean for an object to be polarized

the + and - charges move away from each other

Because a polarized object has not gained or lost electrons, but just has them moved around, the charge of a polarized object is____

Neutral

How can a charged object attract a neutral (polarized) object?

the charge is attracted to the opposite charge within the polarized object.

What is an example of a conductor

Metal

What is an example of an insulator

plastic

what does an electroscope do?

shows whether an object has a charge.

how does an electroscope show if an object has a static charge

the gold foil leaves more.

what would happen to the electric force (Fe) between the two charged objects if the distance between the objects were to triple?

1/9

What would happen to the gravitation force (Fe) between the two objects if the charge were to double

4x bigger

what would happen to the gravitational force (Fe) between the two charged objects if the mass of both objects were to double?

4x bigger
