# What is meant by universal gravitational constant?

**universal constant**relating force to mass and distance in Newton's law of

**gravitation**. Synonyms: G,

**constant**of

**gravitation**,

**gravitational constant**Type of:

**constant**. a number representing a quantity assumed to have a fixed value in a specified mathematical context.

Simply so, what is the value of G?

9.8 m/s^{2}

Additionally, how do you find the universal gravitational constant? According to Newton's law of **gravitation**, F = G M 1 M 2 d 2 , where F is the **gravitational** force between two point masses, M_{1} and M_{2}; d is the distance between M_{1} and M_{2}; G is the **universal gravitational constant**, usually taken as 6.670 × 10^{11} m^{3}/(kg)(s^{2}) or 6.670 × 10^{−}^{8} in centimeter–gram–second units.

Also to know is, what does 9.81 mean?

It **means**, for acceleration of **9.81** (m/s^2), the velocity will increase by **9.81** meter/sec. It **means**, if you let a body fall freely (on earth), then this is the rate at which it will gain in speed towards the ground. It's called the acceleration due to gravity.

What is the SI unit of G?

**g** =Gravity of Earth. **S.I Unit of g** is m/sec -Metre per second. If in newton it is N/Kg -newton per kilogrammes..
