Isaac Newton’s law of universal gravitation describes how the force of gravity works. Which of these statements accurately describes Newton’s law of universal gravitation?
A
As a planet moves around its orbit, the planet sweeps out equal areas in equal amounts of time
B
The orbit of a planet, or other body, around the Sun is an ellipse, with the Sun at one focus of the ellipse.
C
The square of a planet’s orbital period is proportional to the cube of the planet’s mean distance from the Sun
D
Gravitational force increases as the mass of an object increases or as the distance between two objects decreases.
Explanation: 

Detailed explanation-1: -What is Newton’s universal law of gravitation? Newton’s Law of Universal Gravitation states that every particle attracts every other particle in the universe with force directly proportional to the product of the masses and inversely proportional to the square of the distance between them.

Detailed explanation-2: -When the distance between two objects increases, the force of gravity decreases.

Detailed explanation-3: -Legend has it that Isaac Newton formulated gravitational theory in 1665 or 1666 after watching an apple fall and asking why the apple fell straight down, rather than sideways or even upward.

Detailed explanation-4: -Which statement describes Newton’s law of universal gravitation? Every object in the universe attracts every other object.
