The following statements are true about gravitational force:
-
It is directed inward from the center of an object. - Gravitational force acts as an attraction between masses, pulling them toward each other.
-
It gets stronger as two objects are brought closer together. - According to Newton's Law of Universal Gravitation, the gravitational force increases as the distance between two masses decreases.
-
It gets weaker as the mass of an object decreases. - The gravitational force is directly proportional to the masses involved; if an object's mass decreases, the gravitational force it exerts diminishes.
-
It exists between any pair of objects. - Gravitational force exists between any two masses, regardless of whether they are touching or not.
Thus, the false statements are:
- It is directed outward from the center of an object. (False)
- It exists only between objects that are touching one another. (False)
So the true statements are the ones that indicate an inward direction, that gravitational force increases with proximity, decreases with mass, and that it exists between any pair of objects.
