position

· 2 mins read
  • Position is the point or area occupied by a physical object 1.
  • Position in physics means a unique location in space with reference to an origin 2.
  • Position is defined as the translational distance from a parent frame origin to a child frame origin 3.
  • In geometry, a position or position vector, also known as location vector or radius vector, is a Euclidean vector that represents a point $P$ in space 4.
  • At a certain time $t$, the position of a particle may be specified by giving its coordinates $x(t)$, $y(t)$, and $z(t)$ in a particular Cartesian frame of reference 5.
  • Specifying the position of an object is essential in describing motion 6.
  • Position is a vector quantity that specifies the location of a point or object in space with respect to an origin 7.
  • Two quantities, distance and direction, together specify the position 8.
