Apparatus which will demonstrate the conservation of linear momentum is usually expensive or complicated. This is not really surprising if we consider the requirements. First of all friction must be negligibly small, and secondly an accurate method of measuring velocity must be found. The linear air track satisfies the first of these needs, and stroboscopic photography or electric stop clocks can be used to measure velocity.
