study guide - gravity (mass and distance)
multiple choice
identify the choice that best completes the statement or answers the question.

1. spi 0807.12.5 (gravity - mass and distance)

why are mass and distance two key important concepts regarding gravity?
a. because an object with no mass has more gravity and the effect of gravity always increases when objects are farther away.
b. because an object with more mass has more gravity and the effect of gravity increases or decreases depending on the distance
c. because an object with less mass has more gravity and the effect of gravity increases or decreases depending on the distance

Explanation:

Gravity is directly proportional to mass (more mass means more gravitational force) and inversely proportional to the square of the distance between objects. So, the gravitational effect changes depending on distance and mass.

Answer:

b. Because an object with more mass has more gravity and the effect of gravity increases or decreases depending on the distance
