- If you compare the gravitational force on the earth due to the sun to that dueto the moon, you would find that the Sun’s pull is greater than the moon’s pull However, the tidal effect of the moon’s pull is greater than the tidal effect of sun. Why ?Calculate the difference between the acceleration due to Earth's gravity at Moon's center and the acceleration on Moon's surface at the point closest to the planet.Why our mass reduces on moon?
