If you wanted to reach a point where Earth's gravity no longer has a hold on you, you'd have to fly out about 21 million kilometers, or 13 million miles.
If the earth were about 36,000 km in diameter with the same mass and length-of-day then the gravity at the equator would be zero. This is the altitude of geostationary orbits.
The gravitational acceleration decreases with altitude, as shown by the solid line in Figure 1 (left). g is equal to 9.5 m/s2 at 100 km altitude, which is 9% larger than 8.7 m/s2. However, at 500 km altitude, g is close to 8.45 m/s2, which is close to 3% smaller than 8.7 m/s2.
Mount Nevado Huascarán in Peru has the lowest gravitational acceleration, at 9.7639 m/s2, while the highest is at the surface of the Arctic Ocean, at 9.8337 m/s2.
g is the acceleration due to gravity at the surface of the earth. So the value of g decreases as we go to a depth from the surface of the earth. So the maximum value of g is at the surface of the earth.
Now, in a paper published on the pre-print server arXiv, three physicists, claim that the maximum gravitational field humans could survive long-term is four-and-a-half times the gravity on Earth.
Increasing gravity 100x would increase your weight by the same amount. You would suddenly weigh 150,000 lbs. It would be like having a army tank dropped on you from about 10 feet up. This is death equivalent to you stepping on an insect.
As every object will be out of balance for those 5 seconds, the earth's atmosphere will start to disappear, its core will expand with the heat of the sun, the surface of the earth will begin to crack, tidal waves will soar high and other sudden changes will start coming to life.
gravity is significantly less on high mountains or tall buildings and increases as we lose height (which is why falling objects speed up) gravity is caused by the Earth spinning. gravity affects things while they are falling but stops when they reach the ground.
The force of gravity is stronger at sea level.
The gravitational force, as explained by Newton's Law of Gravitation, is inversely proportional to the square of the separation between the two masses (or the separation between the centers of mass for the two objects).
At which height from the earth's surface does the acceleration due to gravity decrease by ? Thus, at 32km above earth surface g becomes 1% of its value on earth surface.
Note that because up is positive, the initial velocity is positive, as is the maximum height, but the acceleration due to gravity is negative.
No, definitely not. Clocks tick slower in more gravity, but the time on clocks has nothing to do with aging. The force of gravity is the cause of motion and stress that causes physical age. Time is the measurement of the duration of motion, and gravity is the cause.
Previous research has shown that spending time in space causes bone density loss, immune dysfunction, cardiovascular issues such as stiffening of arteries, and loss of skeletal muscle mass and strength in both humans and rodent models. These changes resemble aging in people age on Earth, but happen more quickly.
So depending on our position and speed, time can appear to move faster or slower to us relative to others in a different part of space-time. And for astronauts on the International Space Station, that means they get to age just a tiny bit slower than people on Earth. That's because of time-dilation effects.
World Least Gravity- Hiriwadunna, Sri Lanka
Sri Lanka and south India has least gravity level on the earth. As you say this is almost the equatorial region and this area has minimal gravity as measured by the Sri Lankan government. The point on the Earth's surface with the lowest gravity is Hiriwadunna in Sri Lanka.
Hence, acceleration due to gravity decreases with increase in depth.
Yes, weight drops as you go up in altitude (because of diminishing gravity), though your mass remains the same. However, the effect is not huge. In Mexico City, you'd only weigh 0.1% less than at sea level.
It is unlikely that a human could survive for an extended period of time on a planet with 10 times the Earth's gravity. It seems unlikely. Very few humans in a centrifuge can remain conscious for more than a few seconds at 10 g's, and that is sitting stationary in a specially molded chair.
At 11km/s you can successfully break orbit and escape the gravitational pull of the Earth. At 10km/s the Earth will eventually slow down your ascent till you begin falling back towards the ground. These values are at ground level. Once in orbit the escape velocity is lower than 11km/s.
If the hypothetical super-Earth were even bigger, say, 10 times its current mass, dramatic changes could start happening in Earth's interior. The iron core and liquid mantle would also be 10 times larger, and with more gravity acting on a larger mass, the pressure beneath Earth's surface would increase.
Our heart can barely cope with around 5 g of gravity, above which we'd start to pass out.
Normal humans can withstand no more than 9 g's, and even that for only a few seconds.
Jupiter is made up almost entirely of hydrogen and helium, with some other trace gases. There is no firm surface on Jupiter, so if you tried to stand on the planet, you sink down and be crushed by the intense pressure inside the planet.
