Law Of Conservation Of Mess.
Law Of Conservation Of Mess (Collision In 2-D Apparatus) The apparatus consists of an attractive and durable curved track grooved in the middle on which rools a steel ball, can be clamped on the table. A levelling screw is provided under the base to make the lower end of track horizontal. The track carries an adjustable automatic release system to permitting of the ball at exactly the same starting point for multiple runs. An adjustable support attached to base holds the second ball directly in the path of the first, or displaced from the path to cause the collision to occur at different angles and at different distance from the end of the track.
