Question 9 • Physics

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

Newton’s theory because he suggested that the greater the distance between objects, the greater the pull of gravity

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

Newton’s theory because he suggested that the greater the distance between objects, the weaker the pull of gravity

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

Explanation

Newton’s law of universal gravitation says that gravitational force decreases as the distance between two objects increases. So Newton’s theory explains why changing the distance changes the pull of gravity, and choice C states the correct relationship. Choice A reverses it: greater distance means a weaker, not stronger, pull.
