Electric Fields Flashcard

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

How do electric field lines behave around positive charges?

Back

Electric field lines point away from positive charges.

Front

How do electric field lines behave around negative charges?

Back

Electric field lines point toward negative charges.

Front

What does it mean when electric field lines are close together?

Back

It indicates a strong electric field and a strong force between charges.

Front

What does it mean when electric field lines are far apart?

Back

It indicates a weak electric field and a weak force between charges.

Front

Can electric field lines cross each other?

Back

No, electric field lines cannot cross each other.

Front

What do electric field lines represent?

Back

They represent the direction a positive test charge would move in the electric field.

Front

What is the direction of electric field lines around a negatively charged object?

Back

Electric field lines point inward, toward the negatively charged object.

Front

What is the relationship between electric field strength and distance from the charge?

Back

Electric field strength decreases as the distance from the charge increases.

Front

What is a test charge?

Back

A test charge is a small positive charge used to measure the electric field without disturbing it.
