The Value of g Depends on Location
| Location | Distance from Earth’s center (m) | Value of g (m/s2) |
|---|---|---|
| Earth’s surface | 6.38 x 106 m | 9.8 |
| 1000 km above surface | 7.38 x 106 m | 7.33 |
| 2000 km above surface | 8.38 x 106 m | 5.68 |
| 3000 km above surface | 9.38 x 106 m | 4.53 |
Also, at which point of Earth gravity is zero?
The correct answer is At the centre of the Earth.
Beside this, does zero gravity exist?
The sensation of weightlessness, or zero gravity, happens when the effects of gravity are not felt. Technically speaking, gravity does exist everywhere in the universe because it is defined as the force that attracts two bodies to each other. But astronauts in space usually do not feel its effects.
How much weight does gravity impose on our bodies?
Because of earth’s gravity, this mass pushes down on the square meter with a force of about twenty thousand pounds, which is the same as the weight of an empty school bus.
How strong is Earth’s gravitational pull?
The force of Earth’s gravity is the result of the planets mass and density – 5.97237 × 1024 kg (1.31668×1025 lbs) and 5.514 g/cm3, respectively. This results in Earth having a gravitational strength of 9.8 m/s² close to the surface (also known as 1 g), which naturally decreases the farther away one is from the surface.
Is gravity on Earth 1g?
The acceleration of an object toward the ground caused by gravity alone, near the surface of Earth, is called “normal gravity,” or 1g. This acceleration is equal to 32.2 ft/sec2 (9.8 m/sec2). If you drop an apple on Earth, it falls at 1g. If an astronaut on the space station drops an apple, it falls too.
Is there weight in gravity?
That is, the weight of an object is determined by the pull of gravity on it. Thus, an object’s physical weight may change from place to place: if a body weighs 54 kg on Earth, its weight will be just over 9 kg on the Moon, since the Earth’s gravitational force is six times stronger than the Moon’s.
What if gravity was 10x stronger?
So, if Earth’s own gravity suddenly increased tenfold, everything would change and not for the better. Assuming that the force sky-rocketed without any alterations to Earth’s general composition, a ten G scenario would see everybody and thing within Earth’s sphere of gravitational influence weigh ten times as much.
What is difference between gravity and weight?
The weight of an object depends on that object and the gravitational field. Weight is a force, therefore, it is a vector, while gravity is a concept. However, the gravitational field intensity at a certain field is a vector, while the gravitational field intensity over the space is a vector field.
