The balls used in the game of lawn bowls are biased so that they travel in a curved path of decreasing radius. When a bowl in motion collides at a glancing angle with another bowl at rest, it -appears- to increase its velocity. Due to conservation of linear momentum the post-collision velocity cannot be greater than the pre-collision velocity, yet the velocity does -appear- to increase. This may just be an illusion or is there some way that the pre-collision angular momentum is converted to linear momentum due to the collision?
