A circle
Every object is 3 dimensional, no matter how flat they are!
A square is a two-dimensional shape with four equal sides and right angles, while a circle is a two-dimensional shape defined by a constant distance (radius) from a center point. A sphere is a three-dimensional object where every point on its surface is equidistant from its center, whereas a cube is a three-dimensional shape with six equal square faces. Essentially, squares and circles are flat shapes, while spheres and cubes are solid shapes with volume.
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.
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.
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.
A sphere is a perfectly symmetrical three-dimensional geometric shape where every point on its surface is equidistant from its center. This distance is known as the radius. Spheres have no edges or corners, making them unique among other three-dimensional shapes. Common examples of spheres include balls and bubbles.
... center of the circle.
The figure you are describing is a sphere. In a sphere, every point on its surface is equidistant from a central point, known as the center of the sphere. This constant distance from the center is referred to as the radius. Spheres are three-dimensional shapes and can be found in various contexts, such as in geometric studies and in nature.
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.
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.
