The Abstract In this experiment, we studied the collisions of steel and magnetic pucks, and calculated the momentum and kinetic energy of the pucks before and after the collision. The initial momentum of the steel puck was 0.75 J, and the Fnal momentum of both pucks is 0.67 J. The initial kinetic energy of the steel puck was 0.52 J, and the Fnal kinetic energy is 0.35 J. The initial momentum of the magnetic puck was 0.34 J, and the Fnal momentum is 0.312. The initial kinetic energy was 0.30 J, and the Fnal kinetic energy is 0.21 J. The Introduction The experiment was based on the theory that momentum is conserved in all elastic and inelastic collisions. We performed two different sets of collisions, one

Unformatted text preview: with steel pucks and one with magnetic pucks. We hit one puck with the other, and measured the initial velocity of the Frst puck, then the Fnal velocity of both pucks after the collision. The Error Analysis The percent deviation is calculated on the following pages. The Questions The calculations are reported on the following pages for the y components of momentum, and the conservation of kinetic energy. ±or the steel pucks, the fraction of Fnal kinetic energy to initial kinetic energy is 0.66; for magnetic pucks, it is 0.7. The cross-sectional area of the steel pucks is (1/2)*(0.048)*(0.058) + (1/2)*(0.258)*(0.095) = 0.014m^2. The area of the magnetic pucks is (1/2)*(0.194)*(0.12) + (1/2)*(0.17)*(0.15) = 0.025m^2. The area for the magnetic pucks is larger than the area for the steel pucks....
