Collision Balls

• Description :

  This unique apparatus graphically demonstrates elastic collsions better than any other device, because of its sheer size and the complete absence of friction. Its steel legs support an iron frame from which six steel balls, 35mm in diameter, hang from individual bifilar suspensions. Each suspension can be individually adjusted. Pull one, two or any number of balls back and let your students make the interpretations. If you want fewer than six , place the extras in the depressions on the iron frame without removing them from the apparatus. Includes complete instructions. Size completely assembled : 30 cm Wx31cm Dx32 cm H.
