1. why is the moon’s gravity weaker than earth’s gravity?

2. what two factors affect the force of gravity between two objects?

3. if the distance of two objects decreases, would the force of gravity increase or decrease?

4. consider the law of gravitational attraction. two spheres with a mass, m, are attracted to each other by a force, f. if the distance between the two spheres doubles while the masses remain constant, will the force between the two spheres change? if yes, how?

1 The Earth's Moon has considerably less mass than the Earth itself. Not only is the Moon smaller than the Earth but it is only about 60 percent as dense as Earth. Thus the gravitational attraction on the Moon is much less than it is here on Earth and a person weighs less on the Moon

2 The strength of the gravitational force between two objects depends on two factors mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled the force of gravity between the objects is doubled increases, the force of gravity decreases.

3 If the mass of one of the objects is doubled, then the force of gravity between them is doubled.  If the separation distance between any two objects is tripled (increased by a factor of 3), then the force of gravitational attraction is decreased by a factor of 9 (3 raised to the second power).

4 idk about this one

blah

explanation:

bc blah

this is a good question! i'll do some research and come back when i have the answer!
