Homework Help: Physics

Posted by Adam on Thursday, September 22, 2011 at 12:01am.

In mathematical language, Newton's Law of Gravity expresses the force of gravity, F, between two objects in the following way:

F= (GMm)/r^2

where M is the mass of one object, m is the mass of the other object, r is the distance between the two objects, and G is the gravitational constant. Which of the following statements best describes what this formula says?

a)The force of gravity between two objects depends on the product of their masses and the distance between them.

b)The force of gravity between two objects depends on the sum of their masses and the distance between them.

c)The force of gravity between two objects depends on the product of their masses and the inverse square of the distance between them.

I would say c. Is this right? Thanks
