What is the formula for calculating the gravitational force between two masses?.
- A.F = G(m1 * m2) / r^2
- B.F = m1 * m2 * r
- C.F = G(m1 + m2) / r
- D.F = G(m1 * m2) * r^2
Model answer
What a good answer should say
- F = G(m1 * m2) / r^2
Explanation
Why this works
This formula represents Newton's law of gravitation, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses, and r is the distance between the centers of the two masses.
