PHYIC CALCULATOR
Gravitational Field Strength Calculator
A precise tool.
What is the Gravitational Field Strength Calculator & How does it work?
The gravitational field strength ( g ) at a distance from a mass is given by the formula:
[ g = G frac{M}{r^2} ]
G = gravitational constant, M = mass of the object, r = distance from the center of the mass
This formula calculates the acceleration due to gravity at a specific distance from a massive body. The gravitational constant ( G ) is approximately ( 6.67430 imes 10^{-11} , text{m}^3 , text{kg}^{-1} , text{s}^{-2} ).

Frequently Asked Questions
What is the formula for gravitational field strength?
The formula is g = G * M / r^2, where G is the gravitational constant, M is the mass of the object, and r is the distance from the center of the mass.
How do I use this calculator to find gravitational field strength?
Input the mass of the object and the distance from its center. The calculator will compute the gravitational field strength using the formula g = G * M / r^2.
What is the value of the gravitational constant G?
The gravitational constant G is approximately 6.67430 × 10^-11 m^3 kg^-1 s^-2.
Can this calculator be used for any object?
Yes, the calculator can be used for any massive body where you know its mass and the distance from a point outside of it.
What units should I use for mass and distance?
Use kilograms (kg) for mass and meters (m) for distance to get the gravitational field strength in m/s^2.
How does changing the distance affect gravitational field strength?
Gravitational field strength decreases with the square of the distance from the center of the mass, so doubling the distance reduces the strength by a factor of four.
Is this calculator applicable to planets or stars?
Yes, it can be used for planets and stars. Just input their respective masses and the distance from their centers where you want to calculate the gravitational field strength.
