The formula for universal gravitation is F = G * (m1 * m2)/r^2, where F is the force of gravity, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between the two objects.
The force of gravity is inversely proportional to the square of the distance between two objects. This means that as the radius increases, the force of gravity decreases. In other words, the farther apart two objects are, the weaker the force of gravity between them.
The radius has a direct relationship with the gravitational pull. As the radius increases, the gravitational pull decreases. This is because the farther apart two objects are, the weaker the force of attraction between them.
The radius has an inverse relationship with the orbital speed of an object. As the radius increases, the orbital speed decreases. This is because the farther an object is from the center of mass, the slower it moves due to the weaker gravitational pull.
Yes, the radius of an object can affect its gravitational field. The larger the radius, the larger the gravitational field. This is because a larger radius means a larger surface area for the force of gravity to act upon, resulting in a stronger gravitational field.
