Electric Force

Front

What is static charge?

Back

Static charge is an electric charge that accumulates on the surface of an object, often due to friction, causing the object to attract or repel other objects.

Front

What is the principle behind charging by friction?

Back

Charging by friction occurs when two different materials are rubbed together, causing electrons to transfer from one material to another, resulting in one object becoming positively charged and the other negatively charged.

Front

What happens to the electric force between two charges as they move closer together?

Back

The electric force between two charges increases (becomes stronger) as they move closer together.

Front

What type of charge does an object have if it has more electrons than protons?

Back

An object with more electrons than protons has a negative charge.

Front

What types of charges attract each other?

Back

Opposite charges attract each other; positive and negative charges will pull towards each other.

Front

What types of charges repel each other?

Back

Like charges repel each other; positive and positive or negative and negative will push away from each other.

Front

What is an electric field?

Back

An electric field is a region around a charged object where other charged objects experience a force.

Front

How do electric field lines indicate the strength of an electric field?

Back

Electric field lines are closer together where the field is stronger and further apart where the field is weaker.

Front

What is the unit of electric charge?

Back

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

Front

What is induction in the context of electric charge?

Back

Induction is the process of charging an object without direct contact, where a charged object influences the distribution of charges in another object.
