At what height would you not fall back to Earth?
So, in answer to the original question, the lowest you could orbit around Earth without falling back to the ground is 160 kilometers.
How far up does gravity stop?
The Earth’s gravitational field extends well into space it does not stop. However, it does weaken as one gets further from the center of the Earth. The Shuttle orbits about 125 mi above the surface, roughly the distance between Jackson and Nashville!
At what height above the earth’s surface is the free fall acceleration of a mass equal to G 2?
Its value is 9.8 m/s2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2….The Value of g Depends on Location.
| Location | Distance from Earth’s center (m) | Value of g (m/s2) |
|---|---|---|
| 50000 km above surface | 5.64 x 107 m | 0.13 |
At what altitude above Earth would your weight be one half your weight on the surface?
h is the altitude. Now for you to feel half of your weight, g` should be half of g. This means h should be ~2639 KM (Assuming earth’s mean radius = 6371 KM). So if you reach at a height of about 2700 KM above the sea level, you body will weigh around 30 N.
How far is it from earth to space?
about 62 miles
There’s also fuel problem too. The shortest distance between Earth and space is about 62 miles (100 kilometers) straight up, which by general accord is where the planet’s boundary ends and suborbital space begins.
What is the height above Earth’s surface called?
The term elevation is mainly used when referring to points on the Earth’s surface, while altitude or geopotential height is used for points above the surface, such as an aircraft in flight or a spacecraft in orbit, and depth is used for points below the surface.
At what height above the Earth’s surface would the value of acceleration due to gravity be half of what it is on the surface?
2649.6 km
∴ At a height of 2649.6 km from the Earth’s surface, the acceleration due to gravity will be half its value on the surface.
At what height will a mans weight?
| Adults Weight to Height Ratio Chart | ||
|---|---|---|
| Height | Female | Male |
| 5′ 5″ (165 cm) | 113/138 lb (51.2/62.6 kg) | 122/150 lb (55.3/68 kg) |
| 5′ 6″ (168 cm) | 117/143 lb (53/64.8 kg) | 128/156 lb (58/70.7 kg) |
| 5′ 7″ (170 cm) | 122/149 lb (55.3/67.6 kg) | 133/163 lb (60.3/73.9 kg) |
At what height will a man’s weight be half his weight on the surface of Earth r is the radius of Earth?
Thus, at the height of 2650.96 km the weight of the body becomes half the weight at the surface of the earth.
Why do objects fall toward the center of the Earth?
In order to lose energy and become stable it tries to reach its original position and falls down or tries to reach the surface of the heavy mass and an illusion is created of the object being pulled towards the mass. Gravity is an illusion!!! “Why do objects fall toward the center of the Earth?” Because of gravity.
What is the cut-off distance from Earth’s gravity?
Although gravity gets weaker as you go further out, there is no cut-off distance. In theory, gravity extends forever. However, if you went towards the sun, eventually the sun’s gravity would be stronger than the Earth’s, and then you wouldn’t fall back to Earth any more, even lacking the speed to orbit.
What actually pulls us towards the surface of the Earth?
Nothing actually pulls us. We (objects) do not actually get pulled towards the surface of the earth. Objects (or systems) have a tendency to lower their energy levels and try to achieve a more stable state (less energy =more stability). So if we raise an object or simply move it away from a heavy mass, the energy of the object increases.
How close to the sun can you be pulled by gravity?
That would happen if you went about .1\% of the distance to the sun, or about 250,000 km, or 40 Earth radii. (This is actually less than the distance to the moon, but the moon doesn’t fall into the Sun because it’s orbiting the sun, just like the Earth itself is.) How close does an object have to be to Earth to be pulled by gravity?
