Gravity
One of the four fundamental interactions, gravity is responsible for the fact that any objects with mass attract one another. According to general relativity, it is a space time curvature, but according to quantum mechanics it is the result of exchanges of virtual gravitons.

Why is the satellite affected by the earths gravity?
Both have masses; therefore they attract one another.
Why does gravity hold planets together?
No one really knows how gravity works but what we've observed is that anything that has mass has gravity. So every single piece of matter that makes up a planet is gravitationally attracted to every other piece and they stick together as a unified whole.
Is the gravity on earth strong or weak?
Compared to the moon, it's pretty strong. Compared to Jupiter, it's pretty weak.
What effects does gravity have on planets orbit?
Gravity, together with the planet's total kinetic and potential energy,
completely determines the size and shape of the orbit.
What role does gravity play in the tides cycle?
Gravity is what causes the tides in the first place. The tides are caused by the fact that the Moon attracts the Earth stronger on one side (the side that is closer to the Moon) than on the other side. To a lesser degree, the Sun's gravitation causes the same effect.
How does gravity effect stellar evolution?
Gravity effects stellar evolution by pulling down force on the stars while they are forming. Mass will determine how long the star stays alive and burning.
How can you do away with gravity?
There is not the least shred of evidence anywhere in science that you can.
You can overpower it, as you do every time you walk up a flight of stairs or
lift a book from the table, but gravity is always still there.
Why does gravity pulls objects to earth?
Gravity is the cause of a pair of forces that attract any two specks of mass toward
each other. The forces act along the line between the centers of the objects.
As long as you're anywhere near Earth, the forces of gravity pull the Earth toward
the center of you, and pull you toward the center of the Earth (and they're equal).
Is the force of gravity biggest between Jupiter and calisto or between Jupiter and ganymede?
Look up their respective masses, and their respective distances from Jupiter. Then use the standard formula for gravitational attraction.
Does Uranus have a weak or strong gravity?
If you could do the measurements at the same distance from both planets,
you'd find that the gravitational forces between you and Uranus would be
about 14.5 times as strong as the forces between you and the Earth.
Does Jupiter has a stronger or weaker gravity than earth?
If you could do the measurements at the same distance from both planets,
you'd find that the gravitational forces between you and Jupiter would be
about 318 times as strong as the forces between you and the Earth.
What planet has enough gravity to hold on to most grass?
All of the planets have. Sadly though, Earth is
the only one with any grass to hold on to.
Is mars gravity bigger or lower than earth?
If you could do the measurements at the same distance from both planets,
you'd find that the gravitational forces between you and Mars would only
be about 11 percent as strong as the forces between you and the Earth.
How does gravity effect the velocityof a falling object?
In response to the force of gravity, the downward speed of a falling object would
increase smoothly, constantly, and continuously, at the rate of 9.8 meters per
second faster every second, if it were not for the resistance of the air that a
falling object must plow through. This number is called the "acceleration of gravity"
on Earth ... it's a different number on the moon and on every different planet.
How can gravity be changed by distance?
Force = G(m1m2)/r2
As you see the force of gravity is inversely proportional to the distance between two objects. So, make the distance between the two objects measured for their gravitational force greater and the force of gravity will become weaker.
How do astronauts cope with low gravity?
They wear extra warm suits since the atmosphere is thinner and they have weights in their boots so they don't float away!
What is the acceleration due to gravity on Earth in meters per sec?
[ 9.807 meters per second squared ] is.
Why is gravity the force that causes all types of mass movement?
Gravity is a universal force that attracts all objects with mass towards each other. Due to this force, mass movement occurs when objects are pulled or fall towards the Earth's surface. The strength of gravity depends on the mass of the objects and the distance between them.
What does the force of gravity always have?
The force of gravity always has an attractive nature, meaning that it pulls objects with mass toward each other. This force is dependent on the masses of the objects and the distance between them, according to Newton's law of universal gravitation.
What is the potential energy of hydrogen balloon?
The potential energy of a hydrogen balloon is proportional to its height above the ground. The potential energy is directly related to the altitude at which the balloon is located; the higher it is, the greater the potential energy. The potential energy is determined by the mass of the balloon and the height it has achieved.
