A circle
Every object is 3 dimensional, no matter how flat they are!
The value of the acceleration due to gravity (g) depends on the mass of the Earth and the distance from its center. As an object moves away from Earth, the value of g will decrease because the gravitational force weakens with distance.
A triangle is a two dimensional shape with three straight lines and three vertices. A sphere is a three dimensional object with no straight lines and no vertices and such that every point on its surface is a constant distance from a fixed point. It is not possible to have a triangle sphere.
For gravity to act on every object, two criteria must be met: mass and distance. Every object must have mass, which is a measure of how much matter it contains. Gravity also depends on the distance between objects, with the force decreasing as distance increases.
Yes, a sphere is curved. It has a continuous, smooth surface where every point on the surface is equidistant from the center. This curvature is uniform in all directions, making a sphere a three-dimensional object with no edges or corners.
... center of the circle.
The points are all the same distance from the center of the circle. The distance between the center and any point is the radius of the circle.
Every point on the surface of a sphere is the same distance from a fixed point in 3-dimensional space.
It is always different depending on the object. For example a female humans' center of gravity is in the hip. as a male humans' center of gravity is in the chest. But once you have found the center of gravity in an object the center of gravity should be the same in every object like it.
Every object in the universe exerts a force called gravity on every other object. This force of attraction depends on the masses of the objects and the distance between them, as described by Newton's law of universal gravitation.
Yes. A gravitational force attracts every mass toward every other mass.
