What is Gravity?

• A force that pushes objects together.

• A force that pulls objects towards each other.

• A force that affects objects on Earth only.

Which statement best describes gravitational force?

• Gravitational force only exerts forces on large objects close to them.

• Gravitational force repels masses from each other.

What happens to the forces of gravity between two objects as the distance between them increases? (moves farther apart)

• The gravitational force decreases as the distance increases.
• It stays the same.

• The gravitational force only acts when objects are touching.
