The motion of the Moon orbiting the Earth, and the Earth and the Moon both orbiting the Sun, constantly alters the appearance of the sunlight striking the Moon's surface, as viewed from Earth. This changes in light and shadow gives the different phrases of the Moon.
The solar eclipse occurs when the moon is in between the sun and earth . So because the sun is the center of the solar system and is not supposed to move in it the earth and moon's movement causes the eclipse
The moon changes phases because different portions of the moon are illuminated by the sun, as seen by observers on Earth. The angle formed by the sun, the Earth, and the moon, is constantly changing as the Earth orbits the sun and the moon orbits the Earth.

The moon is let by the sun, with parts of it being obscured when it is in Earths shadow. The part in Earths shadow changed daily, leading to the visible phases of the moon. The entire cycle takes approximately 29 days.
The moon does not change shapes. The shadow of the earth on the moon changes how much of it you can see.Another viewpoint: I think this question is about the "phases" of the Moon.The Moon only appears to change shape during its different phases.Exactly one half of the Moon is in sunlight at any time. The phases occur because the Moon orbits Earth. That causes us to see different amounts of the sunlit Moon, and so its shape seems to change.
the rotation of the moon causes the pattern of the moon phase.
Force
The moon spins
the orbit cause it.
mass and acceleraiton
It changes continually in time with its orbital motion.
lack of atmosphere
The lunar orbit, or maybe more precisely, the mutual earth-moon orbit.Orbit
If your mass has 40 kg on earth what is your mass on moon
F=ma.Or force causes acceleration,which is another way of saying that the motion changes.
The variations in how much reflected sunlight we see as the Moon orbits Earth.
The Earth's and Moon's rotation.
