Question

2 which two measurements are needed to calculate the strength (magnitude) of the gravitational force between objects?the distance between the objectsthe speed of each objectthe size of each objectthe mass of each object

Explanation:

Newton's law of universal gravitation defines the gravitational force between two objects with the formula $F=G\frac{m_1m_2}{r^2}$, where $m_1$ and $m_2$ are the masses of the two objects, $r$ is the distance between their centers, and $G$ is the gravitational constant. This shows the force depends only on the masses of the objects and the distance between them; speed and size are not factors in calculating gravitational force magnitude.

Answer:

The distance between the objects
The mass of each object
