The larger the mass of an object...

• The smaller the force of gravity.

• The larger the force of gravity.

• Mass has no effect on the amount of gravity an object experiences.

As the distance between objects increases...

• The smaller the force of gravity.

• The larger the force of gravity.

• Mass has no effect on the amount of gravity an object experiences.
