What is the radial direction? - Mathematics Stack Exchange
WEBThe radial direction points from the center of the sphere towards the surface. Since the sphere is radially symmetrical, any vector with its beginning at the center point of the sphere and its end point on the surface will qualify.
2.5: Coordinate Systems and Components of a Vector (Part 2)
WEBSep 12, 2022 · The first polar coordinate is the radial coordinate r, which is the distance of point P from the origin. The second polar coordinate is an angle φ that the radial vector makes with some chosen direction, usually the positive x-direction. In polar coordinates, angles are measured in radians, or rads.
Cylindrical coordinate system - Wikipedia
WEBThe ISO standard 31-11 recommends (ρ, φ, z), where ρ is the radial coordinate, φ the azimuth, and z the height. However, the radius is also often denoted r or s , the azimuth by θ or t , and the third coordinate by h or (if the cylindrical axis is considered horizontal) x , or any context-specific letter.
Spherical coordinate system - Wikipedia
WEBIn mathematics, a spherical coordinate system is a coordinate system for three-dimensional space where the position of a given point in space is specified by three numbers, (r, θ, φ): the radial distance of the radial line r connecting the point to the fixed point of origin (which is located on a fixed polar axis, or zenith direction axis, or ...
Geometric terms of location - Wikipedia
WEBAxial – along the center of a round body, or the axis of rotation of a body. Radial – along a direction pointing along a radius from the center of an object, or perpendicular to a curved path. Circumferential (or azimuthal) – following around a …

4.5: Uniform Circular Motion - Physics LibreTexts
WEBSep 12, 2022 · 4.5: Uniform Circular Motion. Page ID. OpenStax. Learning Objectives. Solve for the centripetal acceleration of an object moving on a circular path. Use the equations of circular motion to find the position, velocity, and acceleration of a particle executing circular motion.
16.1: Vector Fields - Mathematics LibreTexts
WEBSep 7, 2022 · In a radial field, all vectors either point directly toward or directly away from the origin. Furthermore, the magnitude of any vector depends only on its distance from the origin. In a radial field, the vector located at point \((x,y)\) is perpendicular to the circle centered at the origin that contains point \((x,y)\), and all other vectors ...
Radial and transverse components - Oxford Reference
WEBApr 11, 2024 · Overview. radial and transverse components. Quick Reference. When a point P has polar coordinates ( r, θ ), the vectors e r and e θ are defined by e r = i cos θ + j sin θ and e θ =− i sin θ + j cos θ, where i and j are unit vectors in the directions of the positive x - and y -axes.
4.4 Uniform Circular Motion - University Physics Volume 1
WEBThe direction of the acceleration vector is toward the center of the circle (Figure 4.19). This is a radial acceleration and is called the centripetal acceleration, which is why we give it the subscript c.
