PRACTICAL INVESTIGATION MOMENTUM AND COLLISIONS

This report will investigate the theoretical velocity of a ball bearing gun. The methods and techniques used to derive the results will be shown along with the possible systematic and random errors caused by experimental limitations.

· Since the track is virtually frictionless and air resistance is neglected, the system is isolated; the net resultant force of the external forces equals zero.

· The total linear momentum of the system before the collision is equal to the total momentum after the collision. Therefore, the total change in momentum of this two-particle system is zero.

· Equation that represents the conservation of momentum:

· The total linear momentum of an isolated system is constant.

· All significant experimental errors have been i

· One (1) Ball bearing. (Weight - 65.9g 0.1, Approx Size - 2cm in diameter)

· The ball bearing used in this experiment, took an average of 1.14 0.1 seconds to complete 0.50 meters.
