Static Electricity

Front

What causes lightning?

Back

Lightning occurs because the negative charges at the bottom of clouds are attracted to the positive charges on the ground, the positive charges at the bottom of clouds are attracted to the negative charges on the ground, and the positive and negative charges inside clouds are attracted to each other.

Front

What is conduction in static electricity?

Back

Conduction is the charging of an object by the contact of a charged object to a neutral object, such as touching a door knob.

Front

What type of charge does a substance have if it has more electrons than protons?

Back

A substance with a higher number of electrons than protons has a negative charge.

Front

What does the term 'static' mean?

Back

The term 'static' comes from the Greek word meaning 'stay'.

Front

What happens when a negatively charged balloon is brought near two cans?

Back

The negative charges in Can A move away from the balloon.

Front

What is static electricity?

Back

Static electricity is the accumulation of electric charge on the surface of objects.

Front

What is the principle of charge conservation?

Back

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

Front

What is induction in static electricity?

Back

Induction is the process of charging an object without direct contact, typically by bringing a charged object close to a neutral object.

Front

What is the difference between conductors and insulators?

Back

Conductors allow electric charges to flow freely, while insulators do not allow charges to flow easily.

Front

What is an example of a conductor?

Back

An example of a conductor is copper.
