|
Which of these choices states Newton’s law of universal gravitation?
|
|
As a planet moves around its orbit, the planet sweeps out equal areas in equal amounts of time.
|
|
|
The orbit of a planet, or other body, around the sun is an ellipse, with the sun at one focus of the ellipse.
|
|
|
The square of a planet’s orbital period is proportional to the cube of the planet’s mean distance from the sun.
|
|
|
Gravitational force increases as the mass of an object increases or as the distance between two objects decreases.
|
Explanation:
Detailed explanation-1: -All objects attract each other with a force that is directly proportional to the product of their masses and inversely proportional to their distance of separation.
Detailed explanation-2: -Answer: The mass of either object increases, the force of gravitational attraction between them also increases.
Detailed explanation-3: -Newton proved that the force that causes, for example, an apple to fall toward the ground is the same force that causes the moon to fall around, or orbit, the Earth. This universal force also acts between the Earth and the Sun, or any other star and its satellites. Each attracts the other.
