User:T.Randall.Scales/kinetic energy vs momentum


 * t = time
 * d = distance
 * v = velocity
 * v = d / t
 * m = mass
 * p = momentum
 * p = mv
 * k = kinetic energy
 * k = mv2 / 2
 * k = p2 / 2m
 * k = p v / 2


 * Newton's laws of motion
 * Conservation of linear momentum
 * Equations of Motion

Observations

 * In a closed system, the center of momentum frame is constant, and can not be altered sans external influence.

Collisions

 * In a perfectly elastic collision in a two body system, relative to the center of momentum frame, the absolute magnitude of momentum (and velocity) of each object is retained by that same object.


 * In an oblique collision of two spheres, relative to the center of momentum frame, a line intersecting the center of both spheres, the center of momentum, and the point of contact will exactly bisect, in the same plane, the angle between the direction a sphere came from, and the resulting direction of travel of that sphere.
