Answer:
A. It is applicable throughout the universe.
Explanation:
Gravity is one of four fundamental forces in nature. The other fundamental quantities are the electromagnetic interaction force, the weak force and the strong force. Simply put, gravity is the magnitude responsible for defining a body's weight, vertical and downward force that holds us together with the planet. Any object that moves in free fall is under the influence of gravity acceleration, which on Earth equals approximately 9.8 m / s2.
From the point of view of mechanics, gravity is the force of attraction that arises between two bodies simply by their presence at a point in space. Newton's law of universal gravitation states that the force of gravitational attraction is directly proportional to the product of masses and inversely proportional to the square of the distance separating the two bodies.
