moving at constant velocity

The distance traveled between two successive initial contact of the right and left foot

Extent of deformation of tissue under loading

Energy due to the deformation of an object; for stretching or compressing, it is equal to half
the stiffness constant of the material times the square of change in length of the object;
expressed as units of length squared; expressed as newtons per square meter or pascals in
SI

Genus of gram-positive bacteria found in the throat, respiratory tract, and intestinal tract
