A) Identify the gravitational force as one of the fundamental forces in nature. B) Describe, qualitatively and quantitatively, Newton’s law of universal gravitation. C) Explain, qualitatively, the principles pertinent to the Cavendish experiment used to determine the universal gravitational constant, G. D) Define the term “field” as a concept that replaces “action at a distance” and apply the concept to describe gravitational effects. E) Relate, qualitatively and quantitatively, using Newton’s law of universal gravitation, the gravitational constant to the value of the acceleration due to gravity. F) Predict, quantitatively, differences in the weight of objects on different planets. ||
