Electric Charge, Force and Fields

Front

What is electric charge?

Back

Electric charge is a property of subatomic particles that causes them to experience a force when placed in an electromagnetic field. It can be positive or negative.

Front

What are like charges?

Back

Like charges are charges that are the same (both positive or both negative) and they repel each other.

Front

What are opposite charges?

Back

Opposite charges are charges that are different (one positive and one negative) and they attract each other.

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 you represent electric field lines?

Back

Electric field lines are drawn from positive charges to negative charges, showing the direction of the force that a positive test charge would experience.

Front

What happens to the electric field strength as you move away from a charge?

Back

The electric field strength decreases as you move further away from a charge.

Front

What is the unit of electric charge?

Back

The unit of electric charge is the coulomb (C).

Front

What are protons?

Back

Protons are positively charged subatomic particles found in the nucleus of an atom.

Front

What are electrons?

Back

Electrons are negatively charged subatomic particles that orbit the nucleus of an atom.

Front

What happens when an object gains electrons?

Back

When an object gains electrons, it becomes negatively charged.
