According to Newton's law of gravitation, the Earth and the Moon are gravitationally attracted to each other. The more massive Earth attracts the Moon with...

• a stronger force than the Moon attracts the Earth.

• a weaker force than the Moon attracts the Earth.

• the same force as the Moon attracts the Earth.

• a force that is sometimes stronger and other times weaker than the Moon attracts the Earth.
