Gravity

Gravity is a force that attracts all objects towards each other. People are attracted towards

the Earth and the Earth towards people, the Moon and the Earth are attracted towards each

other, and the Sun and the Earth are attracted towards each other. All of these attractions

are caused by gravity. Gravitational attraction is greater for more massive objects. Gravity

decreases as distance between the objects increases.

Gravity attracts all things towards each other

Every object in the Universe is being attracted towards every other object by the force of gravity. This means that there is nowhere you can go in the Universe where gravity is not acting. Examples of gravity in action:
  • Gravity holds the atmosphere in place around the Earth.
  • Gravity keeps people on the Earth’s surface.
  • Gravity keeps the International Space Station in orbit around the Earth.
  • kkkk
  • Gravity keeps the Earth orbiting around the Sun.
Isaac Newton was the first to come up with the idea that all objects are attracted towards each other by gravity. Even people are attracted towards each other by gravity, but this force is so small that it is not noticeable. Gravity only becomes noticeable if one (or both) of the objects has a lot of mass, such as the Earth.

There is gravity in space


Earth-Moon system and gravity
Any two masses are attracted towards each other by gravity. This force of gravity causes the Moon to change direction to make it orbit around the Earth.

Gravity doesn’t disappear just because you are above the atmosphere. Even if an object is high above the Earth’s atmosphere, there will still be a strong force of gravity pulling it towards the centre of the Earth. At an altitude of 30 km, you would be above 99% of the Earth’s atmosphere. At 100 km, you would officially be in space, yet the weight force of gravity would still be nearly the same. You and the Earth would still be pulled together.

Isaac Newton worked out that, if the distance from the centre of the Earth doubles, gravity becomes a quarter as much as it was on the surface. A satellite with a mass of 1000 kg has a weight force of 9800 N at the Earth’s surface. The radius of the Earth is about 6366 km, so at 6366 km above the Earth’s surface, the distance from the centre of the Earth will have doubled. The weight force pulling it towards the centre of the Earth will now only be a quarter as much but will still be 2450 N.

So why doesn’t a 1000 kg satellite just fall back to Earth?

Sideways speed keeps satellites in orbit.

As a satellite moves around the Earth in a circular orbit, the direction of the force of gravity is always towards the centre of the Earth.
At an altitude of 100 km, you would be so high that you would see black sky and stars if you looked upwards. If you took a satellite to this height and released it, it would still fall towards the Earth because the force of gravity is nearly the same as it is at the Earth’s surface.

However, if the satellite is given speed in any direction horizontal to the surface of the Earth, it will travel further before it hits the Earth. If it is given enough speed, it will travel so far that, as it curves towards the Earth, it will miss the Earth altogether. At just the right speed, it will move around the Earth in a circular motion. This type of motion and the path that a satellite moves in is called an orbit.

Close to the Earth at an altitude of 100 km, a satellite needs to be moving at 8 kilometres per second (28 000 km/h) to stay in orbit. At higher altitudes, satellites do not need to be travelling as fast. Television communication satellites are at a higher altitude of 36 000 km and only need to travel at 3 km/s (11,000 km/h).

The Moon is 360,000 km from the Earth and only needs to be travelling at 1 km/s to stay in orbit around the Earth.

If there is gravity in space, why do astronauts appear weightless?
Astronauts appear to be weightless for the same reason that a person on a trampoline feels weightless when in the air. There is still the same amount of gravity acting, but there is no floor pushing upwards on the astronaut, so the weight force cannot be felt.

If a person was in an elevator and the cables broke and the brakes failed (we are assured this cannot happen), the person and the elevator would fall towards the Earth at the same rate. The floor would not be holding the person upwards, so the person could enjoy the sensation of weightlessness (for a brief while).

This is the same for astronauts high above the atmosphere on the International Space Station (ISS) at an altitude of about 400 km. Gravity is still strong, but the astronaut and the ISS fall towards the ground at the same rate. They are also both travelling horizontally at 28,000 km/h. As they fall towards the ground, they travel so fast horizontally that they miss the Earth altogether and orbit the Earth once every 90 minutes.

Nature of science

Science ideas change over time. Isaac Newton’s gravity-based world view has since been superseded by Albert Einstein’s ideas that all masses distort space and time. This highlights the fact that science is not a fixed body of knowledge. Although Einstein’s theory is widely accepted, Newton’s law of universal gravitation is still used for practical situations such as satellite motion. Gravity is a force that attracts all objects towards each other.Gravitational attraction is greater for more massive objects.   there is nowhere you can go in the Universe where gravity is not acting.Any two masses are attracted towards each other by gravity. This force of gravity causes the Moon to change direction to make it orbit around the Earth.Gravity doesn’t disappear just because you are above the atmosphere.here will still be a strong force of gravity pulling it towards thecentre of the Earth. At an altitude of 30 km, you would be above 99% of the Earth’s atmosphere. At 100 km, you would officially be in space, yet the weight force of gravity would still be nearly the same.   At higher altitudes

Neighbofil is a bright deserted town with mysterious holes in the  ground and funny people that have weird clothes. I think that the town looks a bit  like the town in simpsons
The plot starts of with a bang with humor  and lots of exciting action and weird and quirky  stuff randomly comes out

Recommendation I recommend this book for anyone you like Zombies,games,laughter.  My opinion I think that this book is awesome because I really liked how There were good detail in the artwork.

Mind Maping

Me Jaxon and  Billy had to make a DLO about  mind  maping It was awsome

Space inquiry

This week we had to something related to space so me and jaxon did Life in space

Si fi story


The year 99345 Colony’s Of the world Have left the Well Known planet Earth. Earth  was great in  79354 It had Luxurious lushish juicy fruit And lot of exotic animals but People did not listen to the Citadel!  The Citadel was the they keep on making advanced AI’s ( known as the Artificial interlergice)


The Ai’s took over most of the earth But not the CBJJ rebellion. They gathered most of the population of Earth and They crafted The ARKOLEIGEIST V That got them off planet Earth But Sadly Some Kids  were enslaved By AI’s to make data chips and ADA pads for the Ai’s.
the leader of the  CBJJ Caleb And his Friends Billy Jaxon and josh  a were destined to Find a new Planet. They Searched for Decades they  and they had to Find a planet quickly or else The Food supply would running out They had success They found a Planet Nequilax Or for  Short Neq. “Yes Oh Yes I knew we would make it” replied Josh “oh wow” in a sarcastic way jackson replied Billy wasn't sure if it was
replied Josh  “oh wow” in a sarcastic way jackson replied  Billy wasn't sure if it was safe. Caleb was Inside
The Ark On the Geo console Caleb pressed the button  and The ark split into 10 Base for the family’s of the
CBJJ everyone
was so happy That they found a New planet and New life . We had a look for materials and take  samples of
it we test it and Had
experiments on the Material and we Used Test subject 123 the Common sheep And found out that it Make
The humans DNA Evolve But it had now changes on the test subject Josh was testing it  Out But He Found
out that The Test subject was regericating out Spores That were a strange Brown colour mixed with
Grey Josh was Curious “what
if if We could use the to make Genetically formed Metal” he wo
nder So he Called it RHODOCHROSITE C he was filled with  joy So Then he put his bio suit on
and got the spore And let it outside. The family’s got out and they

They walked back  to the rover and found  a label on it said AI DESTROYER   On 2 huge rifles. They looked at each other  “ are you thinking about what I am thinking about,” ? Caleb said.   “YEAR LET'S GO BACK TO EARTH AND DESTROY THE AI’s,” billy yield “how can we get back to  earth,’’ Caleb replied ‘’This is how,”.

Billy replied  then he walked over  and press the button and then it transformer into  a mini space voyager 2000 and in seconds they blasted into space and went to earth.




They suited up into their suits and started blasting the AI’s  threw bombs everywhere then blew up Most of The AI’s they couldn't kill anything but they could hack anything they want and so then they hack the space voyager  2000 and flew it into Caleb and Billy so but the mist they just had to kill 4 More AI’s So caleb threw the grenade into the glass dome and they KABOOOOOOOOOM the  glass dome blasted into glass shards.


had a look around to Get Water from the  Ark. But one Adult’s got Lost He Started  know what to do he
Glanced
Mysteriously spore and  Inhaled it in His Pulse started beating fast like Drums then His  Eyes Went White
then His fain’s were Bulging like a Illusion They He Went Metal and Started Attacking the Family  bases
and then It started Ripping the flesh of the Kinds ARrah And The kids got the virus and grew Quad legs
and  cannons on the backs And Started shooting Their families.


Caleb josh Jaxon and billy they Collected all  of the special Bios and armory suits and material  and Jolted onto the rover and Speeded out of the area and explored nequliax they glared with admasement  when they saw all of the Beautiful but dangerous animals.


josh was feeling awful  that he made the spore and killed thousands  of families

But he kept it a secret  and started making weapons and armor for the crew while
Caleb and Jaxon were playing far cry 4  “ha im way better than you at far cry,” yielded jaxon. While They were arguing Billy was Playing  halo 5 Josh Slowly walked to everyone “ the armor suits are done come Have a look,” josh yield josh then the team Look and the awesome armor there colors were pink and  black and black and Neon blue, Red, Green, are the colors of the suits
And the guns   were the same colour of the suits  



So they went  back to the ark and they  Glared at everything it was a huge Infected mess and Then started blasting everything In  the air and ground RRRRRRRRRRRRRRRRRRRRRRRRRRRRR SCreech The door of the Ark smashed open and then all of  the infect people Went psycho boom Pew pew pew all of us started shooting the Infected mob into mush Jaxon got ripped in half in the blink of the  eye bye A obese infected thing. And then Caleb blew it up into smithereens
“We can’t fight  this,” caleb Yield.   Out “YES WE CAN!!!!!!! ” Josh Replied
“THROW THE NUKE QUICK” Billy replied He threw  it to Caleb and then but Brutally Josh Got hammered by the  infected mob and got killed by getting Bitten to death.
“OKAY I WILL THROW THE NUKE IN  3 2 1,” Caleb yeled and then billy quickly used the drop shield BOOOOOOOOOOOOOM!!!!!!!!! SKABOOOOOOOOOM!!!!!!!!!! And sadly only Caleb and billy survived the blast “ why  what I can’t believe it we survived,” billy screamed.




They walked back  to the rover and found  a label on it said AI DESTROYER   On 2 huge rifles. They looked at each other  “ are you thinking about what I am thinking about,” ? Caleb said.   “YEAR LET'S GO BACK TO EARTH AND DESTROY THE AI’s,” billy yield “how can we get back to  earth,’’ Caleb replied ‘’This is how,”.
Billy replied  then he walked over  and press the button and then it transformer into  a mini space voyager 2000 and in seconds they blasted into space and went to earth.
They suited up into their suits and started blasting the AI’s  threw bombs everywhere then blew up
Most of The AI’s they
couldn't kill anything but they could hack anything they want and so then they hack the space voyager  2000
and flew it into Caleb and Billy so but the mist they just had to kill 4 More AI’s So caleb threw the grenade
into the glass dome and they KABOOOOOOOOOM
the  glass dome blasted into glass shards.
