Do you know what is the first paper or book derived the final velocities in terms of initial velocities in one dimension? Elastic Collision in Two Dimension A particle of mass m1 moving with velocity v1 along x-direction makes an elastic collision with another stationary particle of mass m2. For a perfectly elastic collision, e = 1 For a perfectly inelastic collision, e = 0 For all other collisions, 0 < e < 1 One-Dimensional or Head-on Collision If the initial and final velocities of colliding bodies lie along the same line, then or An elastic collision is an encounter between two bodies in which the total kinetic energy of the two bodies remains the same.

Oblique collisions i.e. - [Instructor] So if you powered through the last video, you saw that these elastic collision problems can get pretty nasty, the algebra gets pretty ugly. Collision in 1-D If the initial velocities and final velocities of both the bodies are along the same straight line, then it is called a one-dimensional collision, or head-on collision. Compression and rarefaction waves in an elastic bar, whose dynamics is governed by (21.1). I am researching in the relativistic collisions. One dimensional sudden interaction of masses is that collision in which both the initial and final velocities of the masses lie in one line. 2.
