Electric Charge and Static Electricity

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 is static electricity?

Back

Static electricity is the accumulation of electric charge on the surface of an object, which can occur when two materials come into contact and then separate.

Front

What happens when two objects with the same charge come close to each other?

Back

They repel each other.

Front

What happens when two objects with opposite charges come close to each other?

Back

They attract each other.

Front

What is the unit of electric charge?

Back

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

Front

What is a proton?

Back

A proton is a positively charged subatomic particle found in the nucleus of an atom.

Front

What is an electron?

Back

An electron is a negatively charged subatomic particle that orbits the nucleus of an atom.

Front

What is the charge of a neutron?

Back

A neutron has no charge; it is neutral.

Front

What is conduction in terms of electric charge?

Back

Conduction is the transfer of electric charge through a material, typically through direct contact.

Front

What is friction in the context of static electricity?

Back

Friction is the force that occurs when two surfaces rub against each other, causing a transfer of electrons and resulting in static charge.
