This report will certainly investigate the theoretical speed of a ball bearing gun. The
strategies and techniques used to get the benefits will be displayed along with the
conceivable systematic and random problems caused by experimental limitations.
Debate: Since the observe is virtually frictionless and air level of resistance is
neglected, the system is usually isolated, the web resultant power of the exterior
forces equates to zero. The whole linear energy of the system before the
impact is equal to the total momentum after the crash. Therefore , the
total change in momentum of the two-particle system is zero. Formula that
presents the preservation of momentum: The total linear momentum of your
isolated strategy is constant. All significant experimental errors had been
incorporated into the final velocity result. Aim: To investigate and determine
the muzzle speed of a ball bearing firearm by utilizing what the law states of conservation
of momentum. Determine the actual theoretical velocity using several mathematical
strategies and techniques. Hypothesis: This two-particle method is virtually
separated, thus the entire change in energy is actually zero. Therefore when the two
systems collide, they may exert makes on each other, equal in magnitude yet
opposite in direction. Leading to one put together body that may be equal to the sum
of the momentum in the two particles before the crash. Materials: 1 (1)
Ball bearing. (Weight 65. 9g 0. one particular, Approx Size 2cm in diameter) This will likely be
the projectile that may be fired from your missile launcher. One (1) Cart. (Weight
678. 3g 0. 1) This will end up being the object where the charge is dismissed onto.
One (1) standard Stop watch. (Can compare to 100th of a second) Used to time
the trip of Trolley + ball bearing. 1 (1) Observe. (Measuring unit length
0. 50m 0. 05) Used to information cart and measure displacement. Method/Procedure: 1 )
Prepare trail by aligning it plus the cart to a perfect one hundred and eighty degrees for the
launcher. Length used was 0. 50m 0. 05. 2 . Fireplace the ball bearing into the
cart and time the journey. The ball bearing used in this experiment, took an
typical of 1. 16 0. you seconds to complete zero. 50 metres. 3. Work out the assumptive
velocity in the ball bearing in the clip or barrel of the launcher. Equations used to
determine assumptive final velocity: NOTE: During entire test, safety
eyeglasses are to be donned. Any spectator that is not putting on safety glasses should
observe from a secure distance. Benefits: Errors accounted for: Parallax Problem:
0. 05m Stopwatch/Timing Mistake: 0. 1s Mass dimension error: zero. 1g Documented
measurements (OFCOURSE NOT including uncertainty): Times to get overall trip: 1 . 13s
1 . 13s, and 1 ) 16s Range: 0. 50m Mass of Ball Bearing: 65. 9g Mass of Cart:
678. 3g To determine average period (NOT including uncertainty): To determine mass
of combined body after collision: To determine velocity of mixed body after
collision: h = 0. 50m 0. 05 t = 1 . 14s 0. 1 h = 0. 50m 10% t = 1 . 14 8. 7% To determine
velocity of ball bearing in barrel of missile launcher: The muzzle velocity of
this ball bearing firearm is:. Errors not included into method: The ball
beating by itself has a small drag coefficient, although the basket, which the ball
bearing is definitely fired in, may encounter air scrubbing. All atmosphere
friction/resistance was neglected. Summary: This try things out proved my own
hypothesis accurate. Throughout the whole experiment the general change in
energy equaled zero. When the two particles collided there momentum was
conserved resulting in a single body that was the put together mass and momentum in the
previous body. The result was obtained by recognizing which the initial
velocity/momentum of the ball bearing could possibly be determined by making use of the
preservation of energy law, that as long as the net resultant exterior forces
the same zero, the momentum will be constant. From this exercise We learnt new
method and techniques used in calculating errors and doubt.
