Across:
1	All objects with ______________ are affected by gravity.
6	Newton's Law of Universal _____________ states that all objects with mass are attracted to all other objects with mass.
7	If you double the distance between two objects without changing the mass of either object, the force due to gravity between the objects decreases by a factor of _______________.
8	Newton did not discover gravity; he discovered that gravity is __________________.
10	The gravitational constant G is equal to 6.67 x 10^-11 N*m^2/kg^2 and so is a(n) _______________ number.
11	As the distance between two objects increases, the gravitational force between them _________________, if the masses of the objects remain constant.
12	If two objects have constant masses and remain at a constant distance apart, the gravitational force between them remains _________________.
14	The force due to gravity follows the __________________ Square Law because as the distance between two objects increases, the gravitational force between them decreases as the square of the distance between their centers.

Down:
2	The gravitational force is ALWAYS ___________________.
3	The force due to gravity between the earth and an object is referred to as the object's _______________ when the object is on the earth.
4	If we double the masses of two stationary objects, the gravitational force between the two objects will _________________.
5	If we double the mass of one object without changing the mass of another and without changing the distance between the two objects, the gravitational force between the two objects will _______________.
9	As the masses of two stationary objects increase, the gravitational force between them __________________.
13	According to Newton's _______________ Law of Motion, the gravitational forces exerted by two objects on each other must be equal in strength and opposite in direction.
