Displacement in a plane (given initial and final positions)
Formula
s
displacement
x1
x coordinate of initial position
y1
y coordinate of initial position
x2
x coordinate of final position
y2
y coordinate of final position
Formula description
A displacement is the shortest distance from the initial to the final position of a point P. Thus, it is the length of an imaginary straight path, typically distinct from the path actually traveled by P.
