Which sentence from paragraph 4 most precisely explains the factors that determine the force of
gravity?
01. "Newton went much further than this
qualitative description and wrote down
equations that quantitatively describe the
strength of the gravitational force between
two objects."
O2. "In words, these equations state that the
gravitational force between two bodies is
proportional to the product of their masses
and inversely proportional to the square of
the distance between them."
3. "This 'law of gravity can be used to predict the
motion of planets and comets around the sun,
the moon about the earth, and rockets
heading off for planetary explorations, as well
as more earthbound applications such as
baseballs flying through the air and divers
spiraling poolward from springboards."
4. "The agreement between the predictions and lo
