Understanding Gravity and Magnetism

Choose the correct answer: Gravity and magnetism are similar in that ……..

• they are repulsion forces only.

• they are attraction forces only.

• they are forces that attract all objects.

• we cannot see both of them.

When we throw a ball upward, it comes back to the ground due to.....

• gravity only.

• electricity and mass.

• mass-colour.

• magnetism and electricity.

Gravity and magnetism are ……..

• are two pushing forces only.

• are two pulling forces only.

• have some similarities and some differences.

• both of them attract all types of objects.

Magnets can be made of

• copper.

• glass.

• iron.

• wood.

A magnet attracts certain objects like

• wood and steel.

• iron and copper.

• plastic.

• nickel.

Some materials cannot be attracted to the magnet, because they are

• magnetic materials.

• made of nickel, iron and cobalt.

• non-magnetic materials.

• located at the magnetic field of the magnet.

If we put a piece of aluminum foil and a piece of wood close to a magnet, the magnet

• will attract aluminum foil only.

• will attract wood only.

• will attract both of them.

• will not attract both of them.

All the following materials are called magnetic materials, except

• iron.

• plastic.

• nickel.

• steel.

The area around the magnet in which magnetism can be observed is known

• as a magnetic material.

• as a non-magnetic material.

• as a magnetic field.

• as a magnetic force.

The force of gravity between an object and the Earth increases, when the distance between them increases.
