Electrostatics Review

Front

What is electrostatics?

Back

The branch of physics that studies electric charges at rest and the forces and fields associated with them.

Front

What is the principle of induction in electrostatics?

Back

A method of charging an object without direct contact, where a charged object induces a charge in a neutral object.

Front

What is conduction in electrostatics?

Back

The process of charging an object by direct contact with a charged object, allowing electrons to transfer.

Front

What is the relationship between charge and force in electrostatics?

Back

The force between two charges increases as the magnitude of the charges increases and decreases as the distance between them increases.

Front

What is Coulomb's Law?

Back

A law stating that the electric force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

Front

What happens to the force between two charges if the distance is halved?

Back

The force increases by a factor of four, as it is inversely proportional to the square of the distance.

Front

What is an electric field?

Back

A region around a charged object where other charged objects experience a force.

Front

How do like and unlike charges interact?

Back

Like charges repel each other, while unlike charges attract each other.

Front

What is the unit of electric charge?

Back

Coulomb (C).

Front

What is the concept of electric potential?

Back

The amount of work needed to move a unit charge from a reference point to a specific point in an electric field.
