The gravitational force between Earth and the Moon is 1.982×1020 N. To find this result: Identify the mass of Earth: ME = 5.972×1024 kg. Find the mass of the Moon: MM = 7.348×1022 kg. Calculate ME· MM· G = 5.972×1024 kg · 7.348 ×1022 kg · 6.6743×10-11 m3/(kg·s2)...
Under the influence of gravitational force, the Earth has been orbiting the sun for a few billion years. The moon has been orbiting the Earth for almost as long. As they orbit, every now and then the sun, moon and Earth all line up. The positioning of the moon exactly between the sun...
