Universal Law of Gravitation — Unit test

Question 15 • Crowley Credit Recovery Physics A

Chris is studying the theories of Newton and Einstein.Which theory explains why gravity between two objects changes when the distance between them changes?

Answer
A
Einstein’s theory because he suggested that the more distance there is between objects, the more space-time curves and the greater the strength of gravity is
B
Einstein’s theory because he suggested that the more distance there is between objects, the more space-time curves and the weaker the strength of gravity is
C
Newton’s theory because he suggested that the greater the distance between objects, the greater the pull of gravity
D
Newton’s theory because he suggested that the greater the distance between objects, the weaker the pull of gravity

Explanation

Newton’s law of universal gravitation explains how the force between two objects depends on their separation: as the distance increases, the gravitational pull decreases. In fact, the force follows an inverse-square relationship, so doubling the distance makes the force one-fourth as strong. Therefore, the correct choice is Newton’s theory because a greater distance means a weaker pull of gravity.
