Linear motion (also called rectilinear motion) is a one-dimensional motion along a straight line, and can therefore be described mathematically using only one spatial dimension.
The linear motion can be of two types:
uniform linear motion with constant velocity or zero acceleration;
non uniform linear motion with variable velocity or non-zero acceleration.
The motion of a particle (a point-like object) along a line can be described by its position x, which varies with t (time)

watson and crick brought together data from a number of researchers (including franklin, wilkins, chargaff, and others) to assemble their celebrated model of the 3d structure of dna. in 1962, james watson, francis crick, and maurice wilkins were awarded the nobel prize in medicine.
