16
Q

Mass? (4)

A

1) Measurement= kg.
2) Always stays the same even in space.
3) Not a force.
4) How much ‘stuff’ is inside a thing.

17
Q

Weight? (4)

A

1) Measurement= N
2) Force of gravity on mass.
3) Force
4) Changes depending on gravity

18
Q

Why does only weight change but not mass?

A

-Because when you are in space, the gravity changes but mass stays the same.
-Gravity changes on different planets.

19
Q

Why do some countries not have night?

A

The earth rotates at a tilted axis relative to the sun, and during the summer months, the North Pole is angled towards the sun.

20
Q

Why does the moon appear to change shape?

A

When the moon orbits the earth, the sun lights up different parts of it.

21
Q

Characteristics of planets near and far from the sun

A

Planets near the sun are rocky and hot
Planets far away from the sun are cold and gases.

22
Q

What is the moon?

A

An object that orbits the earth (natural satellite)
