The constant of universal gravitation is A) ~9.81 m/s². B) ~6.67 *10^-11 N • m²/kg². C) ~the gravitational attraction between the masses of any two bodies. D) ~the ratio of the forces of attraction between any two masses. E) dependent on the nearest mass.

Question

Quizplus · Accepted Answer

The constant of universal gravitation is a physical constant that determines the strength of the gravitational force between two objects with masses. Its value is approximately 6.67 x 10^-11 N • m^2/kg^2. Choice A is incorrect as it refers to the acceleration due to gravity on Earth. Choice C is incorrect as it describes the concept of gravitational attraction itself, not the constant that determines its strength. Choice D is incorrect as it describes a concept, not the constant itself. Choice E is incorrect as the constant of universal gravitation is not dependent on the nearest mass.
