1-2 What is gravity?
OBJECTIVE: Explain Newton’s law of gravity.
Key Term
gravity: force of attraction between all objects in the universe
Lesson Summary
• Newton’s law of gravity states that all objects in the universe are attracted to one another because of the force of gravity between them.
• The amount of gravitational force between two objects depends on the mass of each object.
• The force of gravity between two objects decreases as the distance between them increases.
