1.) In what way(s) is Einstein's general theory of relativity superior to Newton's theory of universal gravitation? For each way, give an example of a case where Einstein's theory provides a more accurate description of physical phenomena than does Newton's. (Select all that apply.) A.) Newton's theory originally held that the orbit of a spherical object about another will be an open curve for which the point of closest approach slowly precesses. Einstein's theory correctly predicts that gravitational forces lead to orbits of closed ellipses. B.) Einstein's theory correctly predicts the deflection of light passing near a massive object, while Newton's theory predicts a deflection that is one-half the observed deflection. C.) Einstein's theory correctly predicts that the orbit of a spherical object about another will be an open curve for which the point of closest approach slowly precesses. Newton's theory originally held that gravitational forces lead to orbits of closed…

You may have an image of Sir Isaac Newton sitting under a tree and after being hit on the head by an apple he suddenly "discovered" the Law of Universal Gravitation. In fact, the theory was a result of years’ worth of research, which in turn was based on centuries of accumulated knowledge. He is credited with determining that the following relationship is universal. The gravitational attraction between two objects varies jointly with their masses (m1 and m2) and inversely with the square of the distance (d) between them. By what percent does the force of gravitational attraction change if one mass is increased by 20%, the other mass decreased by 20%, and the separation is reduced by 25%?

1. Compare the gravitational attraction between objects on earth and interaction of celestial bodies in space. Which gravitational force is almost negliable? Why? 2. Discuss why the study of a gravitational field is important.
