## What is beyond outerspace?

If by outer space you mean all that surrounds the Earth and stretches into all directions as far as people can see, then you’re talking about what astrophysicists call the universe..

## How many G’s can kill you?

“The NHTSA standard for a sudden impact acceleration on a human that would cause severe injury or death is 75 g’s for a “50th percentile male”, 65 g’s for a “50th percentile female”, and 50 g’s for a “50th percentile child”.

## Is value of g same everywhere?

The value of g at all place is not the same, it varies. The value of g is more at the poles and less at the equator. Hence on the basis of altitude the value of g changes.

## What is small G in physics?

The acceleration on an object due to the gravity of any massive body is represented by g (small g). The force of attraction between any two unit masses separated by unit distance is called universal gravitational constant denoted by G (capital G).

## How was 9.81 calculated?

In SI units, G has the value 6.67 × 10-11 Newtons kg-2 m2. The acceleration g=F/m1 due to gravity on the Earth can be calculated by substituting the mass and radii of the Earth into the above equation and hence g= 9.81 m s-2. …

## Where the value of g is maximum?

The value of g is maximum at poles.

## What is the difference between G and G in physics?

g is a constant at a given location, which depends upon M and r. Answer. g is the gravitational force exerted by any planet. For earth it’s 9.8m/s2….question_answer Answers(5)Acceleration due to gravity ( g )Universal Gravitation Constant ( G )Value of g=9.8 m/s2Value of G=6.673×10-11 Nm2/kg22 more rows•Sep 20, 2013

## Why is gravity 9.81 ms 2?

Near Earth’s surface, gravitational acceleration is approximately 9.81 m/s2, which means that, ignoring the effects of air resistance, the speed of an object falling freely will increase by about 9.81 metres per second every second.

## What is G called?

G is called Universal Gravitation Constant because its value i.e. 6.67 x 10-11 Nm2kg-2 is constant thought the universe.

## Why is gravity 32?

Gravity will accelerate any object at a rate of 32 feet per second per second. … What it means is that if we fall for one second we’ll reach a speed of 32 feet per second. After two seconds we reach 64 feet per second. The speed rises as the square root of height, but in direct proportion to time.

## Is gravity a repulsive or attractive force?

Both in the Newton theory of gravitation and in the General Theory of Relativity the gravitational force is exclusively attractive one. However, the quantization of gravity shows that the gravitational forces can also be repulsive [3].

## What is difference between G and G Brainly?

Answer. Answer: G stands for Newton’s universal gravitational constant, whereas g stands for the acceleration due to gravity at a certain point. … g = 9.8 m.s-2, g is acceleration due to gravity which is a variable quantity and a vector qualtity.

## How was g calculated?

Cavendish experiment …of the value of the gravitational constant, G. In Newton’s law of universal gravitation, the attractive force between two objects (F) is equal to G times the product of their masses (m1m2) divided by the square of the distance between them (r2); that is, F = Gm1m2/r2.

## What does 9.81 mean?

It has an approximate value of 9.81 m/s2, which means that, ignoring the effects of air resistance, the speed of an object falling freely near the Earth’s surface will increase by about 9.81 metres (32.2 ft) per second every second.

## Why value of g is constant?

The gravitational constant is the proportionality constant that is used in the Newton’s Law of Gravitation. … It is also known as Newton’s Constant. The value of the gravitational constant is the same throughout the universe. The value of G is different from g, which denotes the acceleration due to gravity.

## What is the exact value of G?

standard acceleration of gravityNumerical value9.806 65 m s-2Standard uncertainty(exact)Relative standard uncertainty(exact)Concise form9.806 65 m s-29 more rows

## Does zero gravity exist?

Contrary to popular belief, there’s no such thing as zero gravity. Weightlessness and zero gravity are two different things. The earth’s gravity keeps the moon in orbit. … In other words, they’re basically in a state of constant free fall, and that’s why they’re weightless.
