U2:L1 - Electric Forces Act on Charged Objects

Front

What is electric force?

Back

Electric force is the attraction or repulsion between charged objects. It is a fundamental interaction that occurs due to the presence of electric charges.

Front

What happens to charges when two like charges are brought close together?

Back

Like charges repel each other, meaning they push away from one another.

Front

What happens to charges when two opposite charges are brought close together?

Back

Opposite charges attract each other, meaning they pull towards one another.

Front

What is the unit of electric charge?

Back

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

Front

How does the distance between two charged objects affect the electric force between them?

Back

The electric force decreases as the distance between the charged objects increases, following Coulomb's law.

Front

What is a negatively charged object?

Back

A negatively charged object has an excess of electrons, giving it a net negative charge.

Front

What is a positively charged object?

Back

A positively charged object has a deficit of electrons, resulting in a net positive charge.

Front

What is the principle of conservation of charge?

Back

The principle of conservation of charge states that the total electric charge in an isolated system remains constant.

Front

What is polarization in the context of electric charges?

Back

Polarization is the process where the distribution of electric charges within an object is altered due to the influence of an external electric field.

Front

What is the effect of a charged balloon on neutral objects?

Back

A charged balloon can induce a charge in neutral objects, causing them to become attracted to the balloon.
