Q(1) What is gravity and how does it work?
Gravity is a force that attracts objects towards the center of a star or planet. A magnet has a force of gravity and metal is attracted to the magnet hense gravity pulls.

Definition: a force that attracts a body towards any physical body having mass.

Q(2)

1. What is gravity and how does it work?
Gravity is a force that produce by the things that have mass in the Universe. It pulls everything that has mass to itself, for example the relation between moon and earth. But depending on the distance and the mass of the object.

2. How does gravity control the motions in our solar system?

Gravity of the sun control the distance and the orbit of the planets.

Gravity of sun make sure that all planet won't go out from the track of the planet.

The gravity of sun attraction with other planets and pulled them (From less mass to great mass) to it's track

3. What role did gravity play in the creation of our solar system?
The sun's great gravity pulled on the planet near by in orbit of distance and mass, and create the Solar System.

Q1 What is gravity and how does it “work”?
- Gravity is a force of attraction that exists between any  two masses, any two bodies, and any two particles. Gravity is not just the attraction between objects and the Earth. It is an attraction that exists between all objects, everywhere in the universe.

-If it wasn’t for gravity you would be floating around on earth. For example, with gravity, when you jump you will automatically be pulled down towards the center of Earth, without gravity you would just stay up in the air.

Q1. What is gravity and how does it work?

A force that pulls an object towards each other.

Gravity also makes planet to stay in their own orbit and routes.

Also every object in the universe attracts every other object. The strength of the force of gravity depends on the masses of the objects and the distance between them.

The strength of gravity depends in part on the masses of the each objects.

The force of gravity on an object is known as its weight. Unlike mass, which doesn't change, an object's weight can change depending on its location.

The strength of gravity is also affected by the distance of an object, further the distance less the force of gravity. For example, if the distance between two objects were doubled, the force of gravity between them would decrease to one forth of its original value.

1.What is gravity and how does it "work"?
- The force of gravity is measured in units called newtons. The strength of the force of gravity is between two object depends on the factors.
-Definition of gravity: the force that pulls an object to the ground, for instance the moon towards the Earth of its orbit.
- Relationship between mass/distance/gravity
The strength of gravity affects by the distance between two objects as well as of their mass.
- Relationship between weight/mass/denisty
Mass is the amount of what matter is an object. Weight is the force of gravity or an object as its weights.

Definition of gravity: its the force that pulls every body to its center.

How does it work?:

The gravitational force pulls masses together.

How does gravity control the motions in our solar system?: '

Gravity makes Stars Galaxies and Planets move, also, the planets are spherical because of the gravity

Gravity makes the Solar System move around the galaxy.

The planets in the Solar System, have a different orbit, and that orbit it's kept still by the Gravity, that allows the planets to orbit around the Sun

Everything that has mass in the Solar System, has gravity as well.

Definition of gravity: A force that attracts energy and mass together

How does gravity attract?:
By pulling masses together

mass/distance/gravity:  Gravity is a fundamental underlying force in the universe. The amount of gravity that something possesses is proportional to its mass and distance between it and another object. F = G(mass1*mass2)/D squared.

What is gravity and how does it "work"?
-Gravity attracts all object toward each other

Type of force that gravity is: pull
*relationship between mass/distance/gravity:
The strength of gravity is affected by the distance between two objects as well as their masses.
---> If distance increases, gravity decreases, gravity attracts all objects towards one another, if mass increases, force also decreases, if distance increases, force decreases

*relationship between weight/mass/gravity
---> gravity can't be felt because the strength of gravity depends in part on the masses of each of the objects.
(Unlike mass, which remains the same, the weight of an object can change depending on its location.)

Inertia: The tendency of an object to resist a change in motion.
ex) When you are riding in a car and it stops suddenly, you keep moving forward
---> When an object mass increases, inertia increases
This can relate to Newton's first law of motion
"an object at rest will stay at rest and an object in motion will stay in motion with a constant speed and direction unless acted on by a force."

Orbital Motion: Newton concluded that two factors-inertia and gravity- combine to keep Earth in orbit around the sun and the moon in orbit around Earth.
---> Earth's gravity keeps pulling the moon toward it, preventing the moon from moving in a straight line. At the same time, the moon keeps moving ahead because of its inertia. If not Earth's gravity, inertia would cause the moon to move off through space in a straight line.

-Definition of Gravity: A force that attracts all objects toward each other

-Type of force that gravity is: Pulling

-Mass: amount of matter in an object

-Weight can change depending on its location like on different planets

-Strength of force of gravity between 2 objects depends on 2 factors=masses of objects/distance between them

-Distance: Strength of gravity is affected by the distance between 2 objects/masses

How does gravity control the motions in our solar system?
-Sun/Earth=constantly pulling on one another because of gravity

-Earth doesn’t fall in sun/Moon doesn’t fall in Earth—Factor-Inertia

-Inertia-Tendency of an object to resist change in motion

-More mass object of has=greater inertia

-Newton’s first law of motions-object at rest will stay at rest/object in motion will stay in motion without being stopped

-Earth/moon remain their orbits—Inertia/Gravity

What role did gravity play in the creation of our solar system?

-Solar nebula-giant cloud of gas/dust formed our solar system maybe by an explosion of a star-supernova

--Planets created by Gravity of rock and minerals

-Then Gravity pulled most gas in center of disk== Sun creating

-Planetesimals-Gas/dust formed small asteroid-like bodies/formed building blocks of planets/eventually becoming planets

-Inner planets-When solar system formed temp=high/gases escaped gravity forming inner planets/terrestrial

-Outer planets-As planets grew gravity increased/capture hydrogen/helium h=gas in surrounding space

Q1) What is gravity and how does it work?
Ans) Every object in space has a gravitational pull on every other object,
and so gravity affects the routes taken by everything traveling through space.
It’s like the glue that holds together galaxies.
It keeps planets in orbit.
It makes it possible to use human-made satellites and to go to and return from the Moon.
the force of gravity is measured in neutrons
the force of gravity depends on two things: masses of the objects and the distance between them
the more the distance, the less the force of the gravity
the force of gravity on an object is its weight

Q2) How does gravity control the motions in our solar system?
Ans)
•Gravity affects the routes taken by everything traveling through space. It’s like the glue that holds together galaxies.
•It keeps planets in orbit.
•It makes it possible to use human-made satellites and to go to and return from the Moon.

Q3)what role did gravity play in the creation of the solar system when the nebula started
to spread, gravity started to pull in stardust and to pull in debris and rocks to start creating
planet earth. but earth would not have been created unless the sun had started to form, and as it formed it let a big blast
of solar energy lose, blasting meteors and debris to the edge of the solar system.

1-1) What is gravity and how does it work?
- Gravity is a force by which planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit all around the sun
- Attracts all objects to each other.

1-2) Mass/ gravity/ distance
- Gravity attracts all objects toward one another.
- If the mass increases, the force also increases.
- If distance increases, force decreases.
- The strength of gravity is affected by the distance between two objects as well as their mass.

1-3) Gravity/ mass/ weight
- Mass is the amount of matter on an object.
- The force of gravity on an object is weight.

2-1) How does gravity control the motions in our solar system?
- Gravity is very important to force. Every object in space exerts a gravitational pull on every other, and so gravity influences the path taken by everything traveling through space.
- It is a glue that holds entire galaxies.

2-2) Sun, moon, planets, asteroids, other orbits
(How do they work?)
- The factor is called inertia.
- interia: The tendency of an object to resist a change in motion.
- Orbital Motion: Newton concluded that two factors-inertia and gravity- combine to keep Earth in orbit around the sun and the moon in orbit around Earth. Earth's gravity keeps pulling the moon toward it, preventing the moon from moving in a straight line. At the same time, the moon keeps moving ahead because of its inertia. If not Earth's gravity, inertia would cause the moon to move off through space in a straight line.

3-1) How stars are born?
- When atoms of light elements are squeezed under enough pressure for their nuclei to undergo fusion.
- Force of gravity compresses atom interstellar gas until the fusion reacts begin.
