WebMay 12, 2024 · The moon is moving approximately 3.8cm away from our planet every year. The origin of the name is from the Anglo-Saxon word “Mona” for the moon. Diameter: 3476 km. The average distance from the moon to Earth is 360,000 km. Moon’s gravity is about 0.17 of Earth’s gravity. Moon’s orbit speed is 3600 km per hour. WebMost physics books will tell you that the acceleration due to gravity near the surface of the Earth is 9.81 meters per second squared. And this is an approximation. And what I want to do in this video is figure out if this is the value we get when we actually use Newton's law of universal gravitation.
