Gravity Quiz

What is gravity described as in the text?

• A force that pushes every object away from each other

• A force that pulls every object toward every other object

• A force that only acts on certain materials like iron

• A force that can be felt equally between all objects

Why do you not float away into space, according to the text?

• Because the Earth is spinning very fast

• Because gravity is pulling you towards Earth

• Because the air pressure keeps you on the ground

• Because you are too heavy to float

What determines the strength of the gravitational pull between two objects?

• The color and material of the objects

• The distance and mass of the objects

• The temperature of the objects

• The surface area of the objects

According to the text, what is always true about gravity?

• It only acts on objects made of certain materials

• It is a force that can push and pull

• It is a force that only pulls and never pushes

• It can be felt equally between all objects

What is magnetism primarily described as in the text?

• A type of energy

• A force between certain objects

• A scientific theory

• A chemical reaction

According to the text, what can magnets be made of?

• Plastic

• Wood

• Iron

• Glass

What happens when the north pole of one magnet is near the south pole of another magnet?

• They repel each other

• They do not interact

• They attract each other

• They become demagnetized

What is formed by the magnetic force of a magnet?

• A magnetic field

• A gravitational pull

• An electric current

• A light spectrum

How can the shape of a magnetic field be visualized according to the text?

• By heating the magnet

• By placing it in water

• By using a compass

• By sprinkling iron bits on paper placed over the magnet

Why does a compass needle always point north?

• A) Because it is attracted to the Earth's core.

• B) Because the magnetic needle aligns with Earth's magnetic field.

• C) Because it is programmed to point north.

• D) Because it aligns with the Sun.
