U7L2 Electrical Forces

Front

What is Coulomb's Law?

Back

Coulomb's Law describes the force between two charged objects, stating that the force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

Front

What happens to the electric force as the distance between two charges increases?

Back

The electric force decreases as the distance between two charges increases.

Front

What is an electric charge?

Back

An electric charge is a property of subatomic particles that causes them to experience a force when placed in an electromagnetic field.

Front

What are the two types of electric charges?

Back

The two types of electric charges are positive and negative.

Front

What is static electricity?

Back

Static electricity is the accumulation of electric charge on the surface of objects, which can cause them to attract or repel each other.

Front

What is the process of charging by friction?

Back

Charging by friction occurs when two objects are rubbed together, causing electrons to be transferred from one object to another.

Front

What is induction in terms of electric charge?

Back

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

Front

What is the definition of 'attract' in terms of electric forces?

Back

To attract means to pull toward something, as in the case of opposite charges.

Front

What is lightning?

Back

Lightning is a sudden discharge of electricity in the atmosphere, typically occurring during a storm when negative charges in a cloud are attracted to positive charges on the ground.

Front

What is the definition of 'repel' in terms of electric forces?

Back

To repel means to push away from something, as in the case of like charges.
