QUESTION:
When the Moon is in its third-quarter phase, the Earth, Moon, and Sun form a right triangle, as shown in Figure 12–22. Calculate the magnitude of the force exerted on the Moon by (a) the Earth and (b) the Sun. (c) Does it make more sense to think of the Moon as orbiting the Sun, with a small effect due to the Earth, or as orbiting the Earth, with a small effect due to the Sun?
ANSWER:
Step 1 of 6
Part (a)
Consider the Sun, the Earth and the Moon are situated in the vertices of a triangle during the Moon’s third-quarter phase. We are going to find the magnitude of the force exerted on the Moon by the Earth.
The mass of the Earth
The mean distance between the Moon and Earth
The mass of the Moon
The gravitational constant
The force of attraction between the Earth and the Moon
