Newton's Cradle, nine balls In all cases, the momentum of the excited ball(s) will be transferred down the line on balls, exciting an equal amount of balls at the end. For example, one ball given an initial momentum will cause one ball at the opposite end to have the same momentum after collision.

Newton's Cradle, only two balls In this case, the momentum of the excited ball is transferred to the other ball of equal mass. The velocity of the second ball after collision is the same as the first's before the collision due to the conservation of momentum.

Newton's Cradle, big and small ball In this case, the larger massed ball has a low velocity. When the momentum is transferred to a lower mass ball, the velocity must go up in order to maintain the conservation of momentum.

Newton's Cradle, all balls In this case, the momentum of the large excited ball is transferred to balls at the end. The momentum is split primarily between the end three balls, the two inner ones each having a velocity equal to 1/2 of the previous. This gives rise to the doubling in distance seen between the end balls.
