Q2 Interim Review

Front

What happens to the total charge of a system of two blocks before and after a charging process?

Back

The total charge remains the same before and after the charging process.

Front

Can electrons move between two blocks if they are not in contact?

Back

No, electrons cannot move between the blocks without touching.

Front

When an object gains electrons, what charge does it acquire?

Back

Negatively charged.

Front

What is the term for the attraction between two massive objects that are not in contact?

Back

Gravitational Force.

Front

What happens to a magnetic needle placed in the Earth’s magnetic field?

Back

It aligns with the Earth’s magnetic field.

Front

Define electric charge.

Back

A property of matter that causes it to experience a force when placed in an electromagnetic field.

Front

What is the unit of electric charge?

Back

Coulomb (C).

Front

What is the principle of conservation of charge?

Back

The total electric charge in an isolated system remains constant.

Front

What is the difference between conductors and insulators?

Back

Conductors allow the flow of electric charge, while insulators do not.

Front

What is static electricity?

Back

Electric charge at rest, typically produced by friction.
