During a solar eclipse, the moon, earth and sun all lie on the same line, with the moon between the earth and sun. Define your coordinates so that the earth and moon lie at greater x values than the sun. For each force, give the correct sign as well as the magnitude. (a) What force is exerted on the moon by the sun? (b) On the moon by the earth? (c) On the earth by the sun? (d) What total force is exerted on the sun? (e) On the moon? (f) On the earth?

Observing the solar system model of concentric circles with center being the sun. The Earth is 1 AU from the sun. 1 AU is equal to about 150 million kilometers (93 million miles). Using a scale factor of 1010​ meters per astronomical unit (AU); let say that the Earth is 15 meters away from the sun. And let say, Earth takes on an average 365 days to complete a full cycle around the sun. How far Earth travels in its...

During the Apollo missions, astronauts traveled from the Earth to the Moon and back. When they were close to Earth, gravity accelerated them toward Earth, but when they were close to the Moon, gravity accelerated them toward the Moon. However, there is a point somewhere between the Earth and the Moon where they experienced no acceleration due to gravity. The Earth is 6.0×1024 kg, the Moon is 7.3×1022 kg in mass, and the two are 3.8×108 m apart. How far...
