AP Physics 1mediummcq1 pt
The gravitational force between two objects is F. If the distance between them is doubled, the new force is:
A.4F
B.F/4
C.F/2
D.2F
Explanation
Core Concept
Newton's law of gravitation: F = Gm₁m₂/r². If r → 2r, then F_new = Gm₁m₂/(2r)² = Gm₁m₂/4r² = F/4. The force follows an inverse square law.
Correct Answer
BF/4
