A curved surface on which all points are the same distance from the center is called a sphere.
That's a circle. The "fixed point" is the center of the circle, and the constant distance is its radius.
Motion directly either toward or away from the center is 'radial' motion. Motion where the distance from the center is constant is 'tangential' motion.
A sphere.
Downward motion is defined as the movement of one's center of gravity towards the performance surface.
The distance from the surface of the Earth to the center is approximately 6,371 kilometers.
The distance from surface to surface through the center of a planet would be that planet's "diameter".
The distance between the surface at the center of a reflective surface and its focal point is equal to half the radius of curvature of the surface.
A curved surface on which all points are the same distance from the center is called a sphere.
7,000 km
It is the average distance between the centres of the two objects.
That's a circle. The "fixed point" is the center of the circle, and the constant distance is its radius.
The locus of points where the potential due to an isolated point charge is constant is a spherical surface centered on the point charge. This is because the potential decreases with distance from the point charge, so points at the same distance will have the same potential.
No, the radius of gyration is not a constant quantity. It depends on the distribution of mass and the shape of the object. It is defined as the root-mean-square distance of the objects' parts from its center of mass.
The distance from the Earth's surface to its center is approximately 3,963 miles.
The distance between the focal point and the center of a circle is called the radius. It is a fixed distance that remains constant for a given circle.
The average distance from the surface of the Earth to the center is about 6,371 kilometers (3,959 miles).
