Because charged objects can attract other charged objects upward, away from Earth, the upward acceleration due to the electrical charge must be ___ the acceleration downward due to gravity

electrons are transferred from atoms in one object to atoms in the other object

Rubbing two objects such as plastic and wool together creates a static charge because

electrical charge

Bits of paper stick to a plastic comb that has been rubbed because of

separated

When electrons are transferred from one object to another, positive and negative charges are

electrons are free to move around
Electrons can carry electric charges
Electrons can be removed from atoms easily

An important difference between insulators and conductors is that in conductors

like charges repel
charges exert force on other charges over a distance

When an electroscope is charged, its leaves spread apart because

charging by conduction

Touching an electroscope with a negatively-charged rod is an example of

a charged object can be used to charge a neutral object without touching it

In charging by induction

equal to
