Moon’s Gravity

 

 

Find your weight on the moon  

 

 

Gravity is Earth’s gravity – Objects weigh much less on the moon

 

Your Earth weight divided by 6

= Moon weight

 

*Our weight on Earth is 6 x more than on the moon

 Mirror on the Moon                

 

 

 

Sept., April, June and November

 

   February


Scientists left a mirror on the Moon to help them calculate the distance from Earth to the Moon. They knew how fast light travels, they bounced a beam of light from Earth to the Moon and timed how long it took to get back.

never touched the moon’s surface – orbited the moon in the Columbia

Size of Moon

 

 

 

 

 

Diameter is ¼ Earth’s size

 

 

Lunar Month

 

 

 

 

The time that it takes from one full moon to another 29. 5 days

 

 

 

Largest crater on the moon?

 

 

 

 

the largest crater on the moon is called Copernicus

 

 

What causes the phases of the Moon?

 

 

 

The revolution of the Moon around the Earth and its relation to the Sun causes it to appear to change shape

The moon goes through all 8 phases in 29.5 days (its period of revolution)

The moon does not have light, it just reflects the sun’s light

 

 

Compare the period of rotation of the moon

to the period of rotation to the Earth.

**Three theories of how the moon was formed. IN DETAIL!!!!

 

 

 

               

 

 

Moon’s Period of Rotation-

27. 3 Days

Moon revolves around the Earth

 

Earth’s Period of Rotation- 24 hrs

 

 

 


 for Moon

 

 

 

 

1) The moon formed millions or billions of kilometers away and was later captured by Earth’s gravity.

2) The moon formed from the same cloud of gas and dust that the Sun, Earth and the rest of our solar system formed from. The moon rocks lend support to this theory.  Big Bang Theory

*3) A giant asteroid (the size of Mars) hit the Earth and tore a chunk out of Earth’s surface. The Chunk is now our moon (stayed in orbit due to Earth’s Gravity.) The hole that was left on Earth is now the Pacific Ocean. This is also supported by moon rocks.

Near side of the Moon

 

 

 

We never see the Far Side of the Moon

We view the Near Side
