Gravity between Spherical Bodies

Gravity between Spherical Bodies

Newton's law of gravitation describes the gravitational force between any two point masses. However, for extended spherical objects like the Earth, the Moon, and other planets, the law holds with an assumption that masses of spherical objects are concentrated at their respective centers.
This assumption can be proved easily by showing that the expression for gravitational potential energy between a hollow sphere of mass (M) and a point mass (m) is the same as it would be for a pair of extended...

Geoid and Ellipsoid

Geoid and Ellipsoid

The Earth's shape is best described as an ellipsoid, a slightly flattened sphere created by rotating an ellipse around its minor axis. This flattening results in the polar axis being about 21 kilometers shorter than the equatorial axis. In contrast, the geoid represents the Earth's gravitational shape and aligns with the mean sea level (MSL). The geoid is an irregular equipotential surface where gravity is perpendicular at every point. Variations in Earth's mass distribution cause geoid...

Variation in Acceleration due to Gravity near the Earth's Surface

Variation in Acceleration due to Gravity near the Earth's Surface

An object's apparent weight is its weight measured by a spring balance at its location. It is different from its true weight, the force with which the Earth pulls it, because of the Earth's rotation. Mathematically, an object's apparent weight equals its true weight minus the centripetal force that keeps it in a circular motion along with the Earth's surface every 24 hours.
The difference between the true and apparent weights is proportional to the square of the Earth's...

Center of Gravity

Center of Gravity

The center of gravity (COG) of an object is the point where the object's total weight is considered to be concentrated. Knowing the location of the center of gravity is useful when predicting the behavior of a moving object or designing static structures. In a uniform gravitational field, the center of gravity is similar to the center of mass (COM); yet, these two points can be positioned differently. For example, the Moon's center of mass lies very close to its geometric center, but...

Gauss's Law: Cylindrical Symmetry

Gauss's Law: Cylindrical Symmetry

A charge distribution has cylindrical symmetry if the charge density depends only upon the distance from the axis of the cylinder and does not vary along the axis or with the direction about the axis. In other words, if a system varies if it is rotated around the axis or shifted along the axis, it does not have cylindrical symmetry. In real systems, we do not have infinite cylinders; however, if the cylindrical object is considerably longer than the radius from it that we are interested in,...

Gauss's Law: Planar Symmetry

Gauss's Law: Planar Symmetry

A planar symmetry of charge density is obtained when charges are uniformly spread over a large flat surface. In planar symmetry, all points in a plane parallel to the plane of charge are identical with respect to the charges. Suppose the plane of the charge distribution is the xy-plane, and the electric field at a space point P with coordinates (x, y, z) is to be determined. Since the charge density is the same at all (x, y) - coordinates in the z = 0 plane, by symmetry, the electric field at P...

Summary

This summary is machine-generated.

Representational gravity causes memory for target locations to shift downward, especially for the top edge. This effect varies with target size, height, and motion, impacting spatial representation.

Area of Science:

Cognitive Psychology
Visual Perception
Spatial Memory

Background:

Representational gravity describes memory displacement towards implied gravitational pull.
Previous research explored representational momentum for moving objects.

Purpose of the Study:

To investigate if representational gravity effects are uniform across a target's extent.
To examine how target characteristics (size, height, motion) influence representational gravity.

Main Methods:

Participants viewed stationary or moving targets of varying sizes and heights.
Memory for the top and bottom edges of targets was tested after viewing.
Implied gravitational attraction was directed downwards.

Main Results:

Significant anisotropies were observed: top edges displaced downward, bottom edges showed no or upward displacement.
Vertical anisotropies were unaffected by knowing which edge to remember or vertical target motion.
Horizontal target motion showed a trend towards reduced vertical anisotropies.
Larger and higher stationary targets yielded greater displacement, but motion diminished these effects.

Conclusions:

Representational gravity is anisotropic, with differential effects on target edges.
Findings align with representational momentum, suggesting shared mechanisms for spatial representation.
Anisotropies have implications for understanding spatial perception and environmental interaction.
