How does the gravity at the altitude the space shuttle flies compare with the gravity on earth?
if you know earth surface radius and acceleration due to gravity, you can use the following equation to find acceleration at another radius (say geostationary orbit where the communication satellite's are)
.
a = k / ((d/r)^2)
.
where:
a = required acceleration at goestationary orbit ( ? (m/s)/s)
k = earth surface acceleration due to gravity (9.81 (m/s)/s)
d = geo stationary orbital radius (42 170 000 metres)
r = earth surface radius ( 6 371 000 metres)
.
so acceleration at geostationary orbit = 0.224 (m/s)/s
compared to acceleration on earth = 9.81 (m/s)/s
.
say shuttle = 25 000 kg
(weight on earth) f= m*a = 25 000 * 9.81 = 245 250 newtons
(weight at orbit ) f=m*a = 25 000 * 0.224 = 5 600 newtons
note: the force on the shuttle in orbit is balanced by the centripetal force created by its motion in a circle, its required velocity can be calculated from:
v = sq.root(a * d)
v= 3073 m/s
Yes. According to the theory of general relativity, gravity is the result of matter (and more specifically energy) bending space and time.
Concretely this means that time slows down there where gravity is stronger. This implies that time goes quicker for someone in an airplane than for someone on the ground (who is thus deeper in the gravity well of Earth), and this effect has actually been measured. The effect is very tiny because gravity isn't very strong here on Earth so we don't notice it ourselves, but using atomic clocks we can measure it, and it agrees with what Einstein predicted.
In fact the GPS satallites had to have been corrected because their clocks ticked somewhat quicker than those on Earth!
As an extreme example, at the horizon of a black hole the force of gravity is so huge that time stops completely there.
Is it true that gravity acts only on objects on the earth's surface?
No, gravity is a universal force that acts between all objects with mass, not just on objects on the Earth's surface. The strength of gravity decreases with distance from an object, following the inverse square law. This means that gravity affects objects in space as well as on the Earth's surface.
Gravity is a fundamental force of nature that exists throughout the universe and is constantly acting upon objects with mass. It does not need to be "found" as it is always present. Scientists study, understand, and quantify gravity to explain how objects are attracted to each other and how celestial bodies interact in space.
Does gravity pull objects down toward earth?
yes gravity pulls object toward the earth
Here on Earth, the force of gravity does indeed pull objects down toward the Earth. But bear in mind that gravity is a universal force. On the planet Mars, for example, gravity pulls objects toward Mars. All objects in the universe have their own gravitational force, the strength of which depends upon how massive the object is. The sun is much heavier than the Earth, and the gravitational attraction of the sun is enormously greater than that of the Earth.
What role does gravity play in forming galaxies?
Gravity is the force responsible for bringing together gas, dust, and stars within galaxies. It acts to pull these materials closer together, leading to the formation of structures like galaxy clusters and superclusters. Gravity also influences the movements of objects within galaxies, such as stars orbiting around a galactic center.
What are gravity perseus attack?
I'm not familiar with a specific "gravity perseus attack." It is possible that you may be referring to an attack in a video game or other fictional media. Could you provide more context or clarify your question further?
Zero gravity, also known as microgravity, occurs when an object is in freefall and experiences an apparent weightlessness. This is commonly observed in space environments such as the International Space Station. While true zero gravity does not exist in a gravitational field, there are environments in which the effects of gravity are minimal enough to create the sensation of weightlessness.
What substance on earth does the gravity of the moon have the greatest to pull on?
The substance on Earth that experiences the greatest gravitational pull from the moon is the oceans. The moon's gravitational pull causes the tides as it attracts the water on Earth's surface towards it.
How do you create artificial gravity in space?
Good question. currently we don't, but i would think the easiest way would be to have the space station or ship rotate at a specific speed, and then have the rooms angled so you are kind of standing on the side of the ship and the centrifugal force would push you down like gravity, and you could have it spin just right so the force is the same as gravity on earth
What is the number of gravity on Pluto?
The acceleration of gravity on the surface of Pluto is 0.583 m/s2 .
That's 5.94 percent of its value on Earth.
If you weigh 200 pounds on Earth, you would weigh 11pounds 14.2ounces on Pluto.
Is the gravitational pull stronger from Jupiter to the sun or Saturn to the sun?
The gravitational pull from Jupiter to the sun is stronger than the gravitational pull from Saturn to the sun. This is because Jupiter is more massive than Saturn, so it exerts a greater gravitational force over larger distances.
What is the use of gravity disc?
Gravity discs are used to create a gravitational field that can simulate the effects of gravity on objects within a defined area. They can be used in scientific experiments, educational demonstrations, or for entertainment purposes in virtual reality simulations. Additionally, gravity discs can be used in training simulations for astronauts and pilots to experience different gravitational conditions.
Where should the center of gravity be in a rocket?
The center of gravity in a rocket should be located slightly forward of the center of pressure to ensure stability during flight. This ensures that the rocket travels in a straight path without tumbling or veering off course. Placing the center of gravity in the correct position helps the rocket maintain control throughout its flight trajectory.
What is the gravitational theory?
Gravitational Theory is the theory that any two particles of matter attract one another with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
Why has the earth got gravity and the moon has not?
Basically the question is wrong or the concept of gravity in your brain is wrong, as gravity exists both at moon and earth, but the value of "g" varies as at earth it is 9.81m/s^2, and at moon it is some what around 1.8m/s^2.
Is the urine moved down to the ureters into the bladder by gravitational pull alone?
No, urine is moved down to the ureters into the bladder by peristaltic contractions of the smooth muscles in the walls of the ureters. The muscles contract in a wave-like motion to push the urine towards the bladder.
What was the role in gravity on shaping your universe?
Gravity played a crucial role in shaping our universe by bringing matter together to form stars, galaxies, and other structures. It continues to govern the motion of celestial bodies, shaping the evolution and dynamics of the universe on a cosmic scale. Without gravity, the universe as we know it would look vastly different.
When is gravity at the largest?
Gravity is related to Mass and distance. Thus gravity increases the nearer you get to a dense massive body.
How did gravity relate the shape and size of the universe?
Gravity plays a significant role in shaping and determining the size of the universe. The gravitational pull between matter causes regions of higher density to collapse, leading to the formation of structures like galaxies and galaxy clusters. The overall geometry and size of the universe are influenced by the balance between the expansion driven by dark energy and the gravitational pull trying to pull matter together.
How much is Sedna's gravity compared to Earth's gravity?
Sedna's gravity is significantly weaker than Earth's gravity. Sedna is a distant dwarf planet located in the outer reaches of our solar system, and its smaller size and mass result in a much weaker gravitational pull compared to Earth.
the rule of gravity is the greater mass a planet is the stronger its gravitational pull is so the suns mass is so heavy that its gravitational pull is so strong it keeps all the planets in line
I suppose it could exist; water would exert gravitation just like anything else that has mass. Just like our Earth, the planet would have to be either massive enough, or cold enough, to avoid the water vapor gradually evaporating into space.
Yes, gravity is good for us.
-Keeps us on the ground and enable to walk and stand on the earth
-Creates tides in the ocean
-Keeps the moon and the plants in their orbits
-It makes the earth habitable by trapping the necessary gasses and liquids
-Enables us to send satellites into space and retrieve them
How come you measure other planets gravity based on earth's gravity?
We always think of unknown things in terms of things that we do know. So if I tell you that a planet's gravity is 9.8 meters per second squared, is that more or less than you are accustomed to? Could you stand up?
Actually, that IS Earth's gravity, and yes, you can.
