Newton's Law of Universal Gravitation

Back

States that every particle attracts every other particle in the universe with a force proportional to the product of their masses and inversely proportional to the square of the distance between them.

Back

The region around a massive object where other objects experience a gravitational force.

Back

Means two variables have a constant relative ratio or relationship.

Front

Gravity is a force of attraction between all objects with mass.

Back

This force pulls objects toward each other.

Front

What two variables does the strength of gravity depend on?

Back

Mass and Distance. More mass means stronger gravity; greater distance means weaker gravity.
