What is Hooke's Law?
The force applied to the spring is proportional to its extension.
The fore applied to the spring is equal to its extension.

Why does day and night occur?
I need a recap
Because the Earth rotates on it's axis, meaning that when the part of the Earth that we live on is facing the sun, it is day time and when the part of the earth that we live on faces away from the sun, it is night time.
Because the Earth orbits the sun and therefore the Earth isn't always in the same place.
Because the distance between the Earth and the Sun changes. When it's further away, it's night time and when it's closer, it's day time.
How many phases of the moon are there?
8
10
9
7
Which of these are phases of the moon?
Gibbous
Crescent
Full Moon
New Moon
All of these are phases of the moon
Why is it not the same time as the UK in a different country such as Australia?
Because the moon lights up the Earth, which means that day time occurs at different times for many countries. If a country is facing the moon, it is night time because there is no light.
I'm not too sure
Because the Earth orbits the Sun, which means that day time occurs at different times for many countries. If a country is close to the the sun, it is night time because there is no light.
Because Earth rotates on it's axis, which means that day time occurs at different times for many countries. If a country is facing away from the sun, it is night time because there is no light.
Why does the moon appear to change shape on different days?
The moon doesn't emit (give off) any light at all. As the Moon orbits the Earth, the Sun lights up different parts of it, making it seem as if the Moon is changing shape.
Some days, the moon emits more light than others and therefore it appears to change shape.
When it is day time, the moon emits less light than at night time, when it is dark on Earth.
