Electric Charge and Forces Flashcard

Front

What is lightning?

Back

Lightning is a natural electrical discharge of very short duration and high voltage between a cloud and the ground or within a cloud.

Front

How do materials resist current?

Back

Materials resist current by opposing the flow of electrons.

Front

What is charging by induction?

Back

Charging by induction is the process of charging an object without direct contact, typically by influencing the distribution of charges in another object.

Front

What is an electroscope used for?

Back

An electroscope is used to detect electric charge.

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.

Front

What are the two types of electric charge?

Back

The two types of electric charge are positive and negative.

Front

What is Coulomb's Law?

Back

Coulomb's Law describes the force between two charged objects, stating that the force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

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 static electricity?

Back

Static electricity is the accumulation of electric charge on the surface of objects, which can result in a discharge when the charge is released.

Front

What is the difference between conductors and insulators?

Back

Conductors allow the flow of electric charge (e.g., metals), while insulators resist the flow of electric charge (e.g., rubber, glass).
