Identify the true statements about the force that occurs between our planet and the moon that keeps the moon in orbit.

• Gravity is an attractive only force that pulls objects towards other objects

• Magnetism between Earth and the moon is possible due to the composition of metals in the Earth's core

• Friction is a contact or non contact force that increases in strength as distance decreases

• The greater the mass of an object, the greater the force of its gravity on other objects

According to NASA, our moon moves approximately one inch away from Earth each year. If this pattern continues, how could the increased distance affect the strength of the force between Earth and the moon?

• As distance increases, the strength of the force would increase

• As distance increases, the strength of the force would weaken

• The strength of the force would increase and decrease due to other factors

• The strength of the force would not change, because it is not dependent on distance
