Unformatted text preview: ground at the same time because a marble that drops straight down hits the ground at the same time as a ball that travels like a projectile. In the second part of the lab, the smaller marble traveled even further than the smaller marble in part 1 and the big marble ended up in about the same place. The smaller marble traveled further in part two because it was hit by a greater mass. In order to find out whether or not momentum was conserved I used the formula m 1i v 1i +m 2i v 2i = m 1f v 1f +m 2f v 2f . We used a scale to find the mass of each marble. In order to find the velocity we used the formula V x = ∆ X/t. After pluggingin the values for velocity and mass we figured that in both parts momentum was basically conserved. Any differences in momentum were due to friction. In a frictionless environment momentum would have been conserved perfectly....
