Two factors that affect the magnitude of the gravitational force between two objects are...
mass and distance
weight and distance
density and size
mass and weight
Where would an astronaut weigh less on, the moon or Earth?
The moon, since it has less mass, it would have less gravity
The earth, since it has a greater mass,it would have more gravity
The moon, since it has a greater mass, it would have more gravity
The earth, since it has less mass, it would have less gravity
