Question

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

Explanation:

Step1: Recall gravitational force formula

The magnitude of gravitational force is given by $$F = G\frac{m_1m_2}{r^2}$$

Step2: Identify required variables

From the formula, the needed measurements are the mass of each object ($m_1, m_2$) and the distance between the objects ($r$).

Answer:

The distance between the objects, The mass of each object
