This interactive simulation allows students to collide two objects and investigate whether momentum and/or kinetic energy are conserved in the collision process. To keep things simple, the simulation involves an isolated system where the objects collide along a single line. Use the sliders to set...

Wigner3j(j1,j2,j,m1,m2,m) returns the Wigner 3j-symbol, where j1, j2, j, m1, m2, and m are half-integers. Physically, the Wigner 3j-symbol is closely related to the Clebsch-Gordon coefficient , the square of which is the probability that a system of two particles with angular momentum j1 and j2...
