How much does your weight decrease in space?

How much does your weight decrease in space?

Results: We confirmed that spaceflight is associated with weight change (-2.1 +/- 0.1%, N = 514).

What would happen to your weight if the Earth’s radius doubled?

Doubling the mass of the Earth would double your weight, since gravitational force is directly proportional to mass, but doubling the radius (which doubles if the diameter doubles) would decrease your weight by a factor of 1/4, since gravitational force is inversely proportional to the square of the radius.

How does Earth’s radius affect weight?

At the surface of the Earth, M equals the mass of the Earth, and r equals the Earth’s radius. If you are above the surface of the Earth, then r is greater than the Earth’s radius, so the gravitational force (and your weight) would be less. Therefore, below the surface, M would be less and so your weight would be less.

What would happen if the Earth’s radius was doubled?

If we assume that the density of the Earth stays the same, then doubling the radius increases the planet’s mass eight-fold. Surface gravity is now doubled, so most plants and trees promptly fall over.

How much would I weigh in space?

This force of attraction between you and the Earth (or any other planet) is called your weight. If you are in a spaceship far between the stars and you put a scale underneath you, the scale would read zero. Your weight is zero. You are weightless.

How does space affect weight?

In space without gravity pulling down on them, Astronauts are essentially weightless. It is important to explore the difference between mass and weight. While Astronauts may not weigh anything in space and can float around freely, their body shape and size does not change.

How much would a persons weight change if the Earth’s radius increased by 8 times?

With eight times the volume, Earth’s radius would double. This means the gravitational force at the surface would reduce by a factor of (1/2)2 = 1/4, so a person would weigh only one-fourth as much.

What is F GMM R 2?

Description. Sir Isaac Newton’s universal law of gravitation (F=Gmm/r2) is an equation representing the attractive force (F) of two masses (m) separated at distance (r). Force is proportional to mass and distance, related by a proportionality symbol known as the gravitational constant (G).

How do I get 9.8 ms?

In the first equation above, g is referred to as the acceleration of gravity. Its value is 9.8 m/s2 on Earth….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

What if Earth was 2 times bigger?

If Earth’s diameter were doubled to about 16,000 miles, the planet’s mass would increase eight times, and the force of gravity on the planet would be twice as strong. Life would be: Built and proportioned differently. RECOMMENDED VIDEOS FOR YOU…

What happens to your weight as you get closer to the Earth?

Weight and gravitational pull continue to decrease as you get closer to the centre of the Earth. “Imagine you’re standing on a series of balls getting smaller and smaller and smaller. With each one less gravitational force applies,” she says.

What happens if you doubled the mass of the Earth?

Change the way you think and the answer becomes very simple. The earth is attracted to you, if you double its mass, it becomes twice as heavy, it will exert twice the force on you. Just as if you doubled your own mass you would also excert twice the force on the earth.

Is it possible to be weightless in space?

“If you’re right in the centre, if that were possible, and you’ve got the Earth surrounding you, then you’re being pulled equally in all directions and the net effect is that they cancel out. There’s no gravitational pull and you’d be weightless”. But your mass never changes.

What happens if the radius of the Earth increases?

However, if the radius increased along with the mass, with no change to density, then there would be a significant increase in gravity. The radius of the Earth is roughly 3,959 miles so if you were to double that the radius of the Earth would be 7,918 miles.
