Question

Scientists need to know how gravity acts on space shuttles so they can put the space shuttle in orbit. They use an equation that describes how gravity relates to the mass of two objects and the distance between two objects. Which term describes this equation?

Answer 1

The equation is a scientific law, Newton's Law of Gravity,

$F =\dfrac{GMm}{r^2}$

This is a pretty bad question. Newton's Law of Gravity is a mathematical model of gravitation, originally a theory, verified by observation, and now superseded by the General Theory of Relativity.

C is probably the best answer to this poor question.
