The Moon revolves around the Earth primarily due to the gravitational force of attraction between the Earth and the Moon. This force is responsible for keeping the Moon in its orbit around the Earth.
Here's a breakdown of how this works:
Gravitational Force:Gravity is a fundamental force of attraction between objects with mass. The Earth and the Moon exert gravitational forces on each other due to their masses. The gravitational force between the Earth and the Moon is what causes the Moon to revolve around the Earth. This force acts as a centripetal force, continuously pulling the Moon towards the Earth.
Nature of Orbit:The Moon's orbit around the Earth is essentially a type of free-fall trajectory governed by the gravitational interaction between the two bodies. The Moon is not revolving around the Earth due to friction or any kind of surface interaction. Instead, it's the gravitational attraction between the Earth and the Moon that dictates the path of the Moon's orbit.
Role of Inertia:Inertia also plays a crucial role in the Moon's orbit. The Moon, like any object in motion, tends to move in a straight line with a constant speed (in accordance with Newton's first law of motion). However, the gravitational pull of the Earth continuously changes the direction of the Moon's motion, causing it to follow a curved path around the Earth. This curved path is the Moon's orbit.
Centripetal Force:The force that causes the Moon to revolve around the Earth is essentially the gravitational force acting as a centripetal force. This force is necessary to keep the Moon in a stable orbit around the Earth, preventing it from flying off into space or crashing into the Earth.
Tidal friction resulted in a synchronous orbit with the moon, meaning that the moon takes the exact same amount of time to rotate around the Earth as it does to rotate on its own axis. Another impact is slightly slowing down the rotation of Earth on its axis. Moon revolves around the Earth because of Earth’s gravitational pull. The moon exists in the vacuum of space, so there is essentially no force that stops it from moving in and around the earth. The reason for the moon's revolution around earth is the gravitational force that prevents the moon from floating away in space. The moon revolving round the earth in circular orbit is held by the gravitational force of the earth exerted on the moon.Gravitational force exerted by the earth on the moon provides the necessary centripetal force required for the moon to orbit the earth. The moon's velocity and distance from Earth allow it to make a perfect balance between fall and escape. In case the velocity of rotation of the moon was a little bit faster, it would have escaped the Earth's Gravity. On the other hand, if it's a little bit slower, it would have fallen on Earth.
