We use Newton's gravitational constant (G) in finding the acceleration due to gravity of the earth (g). The average value of g is 9.8 m/s2 (it is s square). g is basically the acceleration produced in a freely falling body. For example, if you jump from an airplane in the sky, in 1 second your speed will be 9.8 m/s, in 2 seconds your speed will be 19.6 m/s (9.8 x 2) and so on.
We also use the gravitational constant G to find the gravitational force between 2 bodies. Every object in this universe attracts the objects around it with a force. Even I must be attracting you right now at this moment. But our masses are so less that we do not feel this force of attraction. However, for heavier bodies like planets and stars, we feel this force and call it gravity. The more the mass of a body, the more gravity it has.

What is gravity's number?
42...actually its G=newtons gravitational constant =6.674*10^-11 m^3 kg^-1 s^-2 and is concerned with gravitational attraction calculations.
What is the gravitational force of 7 kg mass exerts on 4 kg mass?
The gravitational force between masses depends on the distance between them. > The force (and reaction) can be calculated from: : f (newtons) = (G * 7 * 4) / d2 where: G = newtons gravitational constant ( 6.672 * 10 -11) d = distance between centres of gravity in metres > Example: a distance of 0.1 metres between the masses would exert a force of on each mass of 1.868 * 10 -7 newtons
Who measured the gravitational constant G?
Cavendish measured the gravitational constant "G".
Why did Einstein have to find a gravitational constant?
The gravitational constant was found by Newton, not Einstein.
When was g the earth's gravitational constant calculated?
g, the force of the Earth's gravitational attraction, is not a constant.
What will the weight of a ball in water be if its weight in air is 2 newtons?
Weight in a constant gravitational field is also constant, regardless of any surroundings. The weight will be two newtons underwater as well.
What does not describe weight a changes as gravitational force changes b is constant c is a mesaure of gravitational force d can be meaured in newtons?
B

What is the force between the earth and a body on earth?
The force between the Earth and a body on Earth is the gravitational force, which is determined by the mass of the Earth, the mass of the body, and the distance between them. This force causes objects to be pulled towards the center of the Earth.
What is Isaac Newtons theory called?
Well he fundamentally proposed a few theories. But he is eminently known for introducing the 'Mathematical Principles of Natural Philosophy'. These principles include Newtons 3 laws of motion and his Gravitational Constant. If you want to know what they are, google, Newtons 3 laws. He was quite smart!
What is the measure of the gravitational force on objects?
Newtons
What is Newtons famous accomplishment?
Gravitational pull
What was the value of gravity in newtons 1 billion years ago?
Gravity is not measured in Newtons. The Gravitational Constant, as its name implies, was the same a billion years ago as it is today, which is: 6.67 × 10-11 m3 kg-1 s-2
Gravitational force is measured in?
It's a force, so newtons, N.
