S8P5 Test Gravity, Electricity, Magnetism, EM Review

Front

What is the orientation of a bar magnet in a magnetic field?

Back

A bar magnet will align itself with the magnetic field lines, with the North pole pointing towards the South pole of the magnetic field.

Front

What factors affect the strength of gravity?

Back

The strength of gravity is affected by mass and distance.

Front

Which material is not a good electrical conductor?

Back

Plastic is not a good electrical conductor.

Front

What happens when two South poles of magnets are placed near each other?

Back

They repel each other.

Front

How does an electric generator work?

Back

An electric generator transforms mechanical energy into electrical energy by spinning a coil of wire near a large magnet.

Front

What are the two poles of a magnet?

Back

A magnet has a North pole and a South pole.

Front

What is the relationship between mass and gravity?

Back

The greater the mass of an object, the stronger the gravitational pull it exerts.

Front

What is the effect of distance on gravitational force?

Back

As the distance between two objects increases, the gravitational force between them decreases.

Front

What is an example of a good electrical conductor?

Back

Copper is a good electrical conductor.

Front

What is the principle behind electromagnetism?

Back

Electromagnetism is the interaction between electric currents and magnetic fields.
