Static electricity

Static Electricity

The build up of electric charge due to the accumulation of electrons on an object.

Friction

The force that causes the transfer of electrons, leading to static electricity.

Negative Charge

An object with more electrons than protons.

Positive Charge

An object with fewer electrons than protons.

Neutral Charge

An object that has an equal number of electrons and protons.

Polarization

The displacement of electrons in a neutral object caused by the presence of a charged object, leading to attraction.

Electrons

Subatomic particles with a negative charge that can move and flow through conductors.

Protons

Subatomic particles with a positive charge that do not move freely like electrons.

Conductors

Materials that allow electrons to flow easily, such as metals.

Insulators

Materials that do not allow electrons to flow easily, such as air.

Winter Static Electricity

Static electricity is more common in winter due to lower humidity, which prevents electrons from escaping.

Attraction of Charged Objects

A negatively charged object attracts a neutral object due to polarization of electrons.

Example of Static Electricity

When a balloon is rubbed against a sweater and then brought near paper, the balloon can attract the paper due to polarization.
