Back

+ (positive) and - (negative)

Front

What subatomic particles are found in the nucleus of an atom?

Back

Protons and Neutrons

Front

What happens to the electric force between two charges when they are close together?

Back

The electric force is strongest when the charges are close together.

Front

What is an electric field?

Back

An electric field is a region around a charged object where other charged objects experience a force.

Front

What do electric field lines represent?

Back

Electric field lines represent the direction and strength of the electric field.

Front

What charge does object A have if it repels object B?

Back

Object A has a positive charge if it repels another positive charge.

Front

What charge does object B have if it attracts object A?

Back

Object B has a negative charge if it attracts a positive charge.

Front

What is the effect of distance on the strength of the electric force?

Back

The electric force decreases as the distance between charges increases.

Front

What is the unit of electric charge?

Back

Coulomb (C)

Front

What is the principle of conservation of charge?

Back

The total electric charge in an isolated system remains constant.
