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.
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.
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
When was g the earth's gravitational constant calculated?
g, the force of the Earth's gravitational attraction, is not a constant.
What is the force between the earth and a body on earth?
The gravitational constant on Earth is 10 Newtons per kg (well exactly about 9.81 Newtons)
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
Which law states The greater the mass the stronger the gravitational force The greater the distance the weaker the gravitational force?
Thats f (newtons) = (G * m1 * m2) / d2 where: G = newtons gravitational constant m1 = mass, object 1 m2 = mass, object 2 d = distance between
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.
How much force would it take to lift a 20kg object on earth?
20x G(gravitational constant 9.81ish) 20x9.81=196.2 Newtons
What is the number of newtons is the gravitational force minus the number of newtons for the drag in water?
That depends how fast the object moves. However, once it falls in the water at a constant velocity, you know that the net force - which is just what the question is after - is zero.
What is Newtons famous accomplishment?
Gravitational pull
What is the measure of the gravitational force on objects?
Newtons
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!
Gravitational force is measured in?
It's a force, so newtons, N.
Who measured the gravitational constant G?
Cavendish measured the gravitational constant "G".
