Why is gravity on earth stronger than gravity on the moon?

Answer 1

Because earth is more massive than the moon. Mass and gravity are positively correlated; the more mass a body has, the stronger its gravity.

1. the earth is larger then the moon and it has electic forces that allow the gravity to be much stronger on the earth then on the moon.

2. the more mass the object has the stronger force of gravity is has

3. if the earth had no gravity there would be no human existence, the moon wouldn't exist and even our plant would exist, the formation of the earth occurred due to the gravitation pull of the magnetic polls on the earth.

Answer 2

Gravity has two rules that affect how it works.

The first is how 'big' something is. Scientists and engineers call this the mass of an object. It describes how much 'stuff' there is.

The second thing that affects gravity is how far away it is from something. There is a mathematical rule here called the inverse square law. That means if you double the distance then you halve the effect. If you triple the distance the effect is one third.

Another funny thing about gravity is that it seems to come from the center of a body. So the gravity of the earth seems to be coming from the center of the earth.

The same is true of the moon.

So we take these things together and use a formula to calculate the gravity on a rock on the moon. When we do the sums it shows that though the earth has a stronger gravitational field than the moon overall, because of the distance the strength is much less than that of the moon. Remember the gravity seems to come from the center, and the center of the moon is much closer to the rock than the center of the earth.

Answer 3

The earth's mass is about 80 times as much as the moon's mass.

Answer 4

There is gravity on the moon. The moons gravity is about one sixth what it is on Earth. The weaker gravity is due to the moon's lower mass.

Answer 5

Because the Earth is more massive.
