Yes, the moon's orbit is slightly eccentric as with all orbits so at times it is closer to earth.
of course you can
the distance
The only way to change anythings gravity is to change its' mass. (apex) Increase the mass of the object Decrease the distance of the object from Earth
Because Earth's gravity is becoming less and less with the larger amount of distance between it and the object.
The exact distance changes, as the moon revolves around the earth in its orbit and as the earth rotates. A reasonable figure for the average distance between the United States and the moon is 238,000 miles.
The moon's distance from Earth increases over time due to a phenomenon called tidal acceleration. This is caused by the gravitational forces between the Earth and the moon, which gradually push the moon into a higher orbit.
The change in its distance from the earth. The distance changes by about 43,000 km which equates to about 4.8 minutes of arc.
You can increase the gravitational potential energy between yourself and the Earth by increasing your height above the Earth's surface. This is because gravitational potential energy depends on the distance between two objects. By moving to a higher position, you are increasing the distance between yourself and the Earth, thus increasing the gravitational potential energy.
An object gains gravitational potential energy when it is raised above the Earth's surface. The increase in distance from the center of the Earth leads to an increase in potential energy due to the gravitational force between the object and the Earth.
As you move away from the Earth by distance squared, the force of gravity (weight) decreases. This is because gravity follows an inverse square law, where the force of gravity weakens as the distance between two objects increases.
distance earth from the sun
Varying from the the distance from the Earth to the Moon + the distance from the sun to the earth + the distance from mercury to the sun, to the distance from the earth to the sun - the distance from mercury to the sun - the distance from the earth to the moon
