Electric Forces

Front

What is an electric force?

Back

An electric force is the attraction or repulsion between charged objects.

Front

What happens to the electric force when the distance between two charged objects increases?

Back

The electric force decreases.

Front

What type of charges attract each other?

Back

Unlike signs (positive and negative charges) attract each other.

Front

What type of charges repel each other?

Back

Like signs (positive-positive or negative-negative charges) repel each other.

Front

What occurs when a neutral object is brought near a charged object?

Back

The charges in the neutral object move around due to the electric field of the charged object.

Front

What is the relationship between charge magnitude and electric force?

Back

The greater the charge magnitude, the greater the electric force.

Front

What is Coulomb's Law?

Back

Coulomb's Law states that the electric force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

Front

If two objects have equal charges, what can be said about the forces they exert on each other?

Back

The forces they exert on each other are equal in magnitude and opposite in direction (Newton's Third Law of Motion).

Front

What happens to the electric force between two charged objects if one charge is doubled?

Back

The electric force between the two objects will also double.

Front

What is the effect of rubbing two objects together on their charges?

Back

Rubbing two objects together can transfer electrons, resulting in one object becoming positively charged and the other negatively charged.
