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.

What is the law of universal gravitation?

• The more mass an object has, the more gravitational attraction it has. The greater the distance between two objects, the less their gravitational attraction.

• Gravity pulled together a cloud of interstellar gas and dust (called a nebula). As the nebula spun, gravity condensed the gases into the center to form the Sun. Eventually, the gravity of smaller pieces of matter drew objects to them to form the planets.

• It states that any two masses attract each other more when they are more massive (greater mass) and closer together (less distance).
