Question 4 • Physical Science

Increasing which factor will cause the gravitational force between two objects to decrease?

Answer
A
acceleration of the objects
B
weights of the objects
C
masses of the objects
D
distance between the objects

Explanation

Newton’s law of gravitation is F = Gm₁m₂/r², so the force decreases when the distance r between the objects increases. Increasing either mass makes the force stronger, not weaker. Therefore, the correct choice is distance between the objects.
