Question

6
the diagram shows a dwarf planet with three moons, each with the same mass. which moon experiences the greatest gravitational force?
a moon 1 because gravity always acts in a downward direction
b moon 2 because it is closest to the dwarf planet
c moon 3 because it is furthest from the dwarf planet
d they all experience the same gravitational force
make an observation!
you will need strong observations to answer the guiding question later on.

Explanation:

Gravitational force between two objects depends on their masses and the distance between them, described by Newton's law of universal gravitation: $F=G\frac{m_1m_2}{r^2}$. Since all moons have the same mass, the force is strongest for the moon closest to the dwarf planet (smallest $r$).

Answer:

B. Moon 2 because it is closest to the dwarf planet
