What is universal about Newton's law of universal gravitation?

Answer 1

Newton's law of universal gravitation is about the universality of gravity. He discovered that gravitation is universal. All objects attract each other with a force of gravitational attraction. Gravity is universal. This force of gravitational attraction is directly dependent upon the masses of both objects and inversely proportional to the square of the distance that separates their centers.

Newton's law of universal gravitation is about the universality of gravity. He discovered that gravitation is universal. All objects attract each other with a force of gravitational attraction. Gravity is universal. This force of gravitational attraction is directly dependent upon the masses of both objects and inversely proportional to the square of the distance that separates their centers.

Answer 3

It is universal because Newton's law of universal gravitation is a law of nature, which means anywhere in the universe the same law of gravity would apply. Universal means it's the same equation anywhere in the universe. This is not to say that gravity is the same everywhere, as it's not. This is to say though that the gravitational constant, or G, is the same constant everywhere. Sort of like the speed of light is the same everywhere.

Answer 4

It is "universal" in the sense that the law of gravity at the surface of our Earth is the same law that applies to planets going around a Sun or a moon going around a planet. Prior to Newton, people just assumed that there was one set of laws to be used on Earth and another set of laws to be used outside of Earth. Although Newton wasn't the first to suggest that there was, indeed, only one set of laws for both situations, he was the first to show what those laws were, and how using this one set of laws could result in what we see, both on Earth and in the heavens.

Answer 5

Well gravity itself is not a force. Gravity is a disturbance in the fabric of space time. Take the three dimensions of space which as you know are movements along the x,y and z axes. In vectorial form, the unit vectors of these three axes are the i, j and k. Keeping in mind i,j and k are vectors. However, the magnitude of every unit vector is one. This becomes more important later in your college career studying physics. Now as far as the force due to gravity known as the gravitational force is certainly universal. This is because between any two objects of mass there is an attractive force. This force is the gravitational force. It is equal to F=GMm/r^2. G is the Gravitational constant, M is the mass of the first object, m is the mass of the second object and r is the distance between them. Notice, the distance between them is squared. Which means as the distance increases the gravitational force decreases. Gravitational force is universal because it doesn't matter how far apart the objects are or how small or large the masses are there is an attractive force between the two objects. However, note that two objects that are an infinite distance away from another there is a gravitational force acting on them. But the force is so small that it is thought of being zero because it's value is so close to zero.

Answer 6

It is considered a universal force because gravity is all around us and can never disappear.

Answer 7

That simply means that EVERY object attracts EVERY OTHER object.
