## Why does the earth have a stronger gravitational pull than the moon?

The greater an object’s mass, the more gravitational force it exerts. So, to begin answering your question, Earth has a greater gravitational pull than the moon simply because the Earth is more massive. That’s why the moon isn’t pulled out of Earth’s orbit by the gravity of larger planets or by the sun.

## Which is stronger the Earth’s pull on the moon or the moon’s pull on the Earth?

Earth exerts a gravitational pull on the moon 80 times stronger than the moon’s pull on the Earth.

## Is Moon moving away from the Earth?

Right now, the Moon is moving away from the Earth at a rate of about four centimeters per year, due to the tidal interaction between the Earth and the Moon. At a basic level, the Moon’s gravity exerts a drag on the Earth that slows its rotation, and the Earth’s gravity exerts a pull on the Moon that expands its orbit.

## What would happen if the moon was farther away?

If the satellite were slightly closer, the tidal bulge would grow. Low tides would be lower and high tides would be higher and any low lying coastline would be flooded. If the Moon got much closer, say 20 times closer, it would exert a gravitational force 400 times greater than what we are used to.

## How fast must the Earth rotate to neutralize gravity?

If we put our value of omega (angular velocity) into the equation we find that T = 5074.99 seconds or 1.409 hours. This means that the Earth would need to rotate with a period of 1 hour 24 minutes.

## What would happen if Earth’s axis was straight up and down?

If the earth weren’t tilted, it would rotate like that as it revolved around the sun, and we wouldn’t have seasonsâ€”only areas that were colder (near the poles) and warmer (near the Equator). But the earth is tilted, and that’s why the seasons happen.

## Why is the earth not vertical or straight?

The Earth itself spins on an axis. The Earth’s axis is vertical, meaning it runs up and down. This movement is called a revolution, which is different from rotation. Objects rotate around an axis, but revolve around other objects.
