Ballistic Pendulum Lab Post 2

Ballistic Pendulum
Observations:
The projectile slowed significantly after the impact and the collision was totally inelastic. Momentum was conserved going in the same direction as the projectile. Initial Velocity before impact is significantly greater than after the collision

Error analysis:
During some of the trials, the gun could of fired the projectile at a slightly different angle thus being off-center with the force and causing different readings to appear. Another potential source of error is that the bob itself was off center creating some trials that had unusable date. For example, sometimes the projectile didn't insert itself into the bob and would just fly off. Another trial would have to be done.

Gun and Carbon Paper:
Observations:
The projectile never hit the same exact spot two times in a row. Each shot was slightly away from the previous one.

Error analysis:
The carbon paper was not off best quality due to age so marking were difficult to see and sometimes totally invisible. Also, the recoil of the gun after each shot could of shifted the position of the whole system by a few microcentimers which could of distorted the angle leading to irregularities when it came down to measureing exact position of impact.
