Gravitational Forces:

These forces are exerted by objects with mass on each other due to gravity. They can be attractive or repulsive depending on whether the masses attract or repel each other.

Gravitational Field: A region around an object where another object experiences a gravitational force. It is created by any object with mass and extends infinitely in all directions.

Inverse Square Law: This law states that a physical quantity (in this case, gravitational force) decreases as the square of the distance from its source increases.
