Atoms contain charged particles called

• protons, neutrons, and electrons.

• protons and electrons.

• protons and neutrons.

• electrons and neutrons.

A region around a charged object where the object's electric force is exerted on other charged objects is an electric

• field.

• outlet.

• socket.

• power plant.

In static electricity, charges

• flow continuously.

• flow intermittently.

• build up in an atom.

• build up on an object.

Charges can redistribute themselves by friction, conduction, polarization, or

• reduction

• production

• induction

• superconduction

Charges that are different repel each other.

• true

• false

An electric field gets stronger the closer it is to the charge.

• true

• false

Charges do not transfer between objects in polarization or conduction.

• true

• false

Lightning is an example of static discharge.

• true

• false

Electric current is the buildup of charges on an object.

• true

• false

Most objects have some overall charge.

• true
