Questions

Gravitational Force Calculator FAQ

How do I enter very large or very small mass values?
Use scientific notation by entering values as 3*10^24 or 3e24 for masses like planetary bodies.
What units does the calculator use for the result?
The gravitational force is calculated and displayed in newtons (N), which can be converted to other units using the site's force converter.
Can this calculator show if two objects will actually attract each other?
Yes, the tool applies Newton's law of universal gravitation, which states that any two objects with nonzero mass will always attract each other, though the force may be too small to notice in everyday situations.
Is the gravitational force always positive?
Yes, the calculator outputs a positive value for force, indicating that the two objects always attract one another rather than repel.
