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 them

When we throw a ball upward it returns back to the Earth due to....

• electricity and mass.

• gravity only.

• magnetism only.

• magnetism and electricity.

The ......of objects and the..... between them affect the gravity force.

• mass color

• distance - mass

• mass - distance

• volume distance

..............is a magnetic material that is attracted to the magnet.

• Copper

• Iron

• Gold

• Wood

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.

When we put a piece of aluminum foil close to a magnet, it will

• be attracted to the magnet.

• be a magnet.

• not attract to the magnet.

• repel with the magnet.

All the following materials are called magnetic materials, except

• iron.

• plastic.

• nickel.

• steel.

Magnet affects certain objects like... when they locate in its magnetic field.

• wood and steel

• nickel and plastic

• iron and copper

• cobalt and steel

Electric insulators like.....and.......do not allow electricity flow through them

• copper and plastic

• rubber and plastic

• rubber and iron

• copper and iron

When electric current flows through your body it

• causes an electric shock.

• increasing your mass.

• decreasing the water level in your body.

• does not affect your body.
