Document Summary
Wooden metre stick, glass marble, launcher, spring, paper, needle. In order to determine the experimental exit speed or velocity of the marble as it was leaving the launcher two figures were needed, time and horizontal distance. Horizontal distance and time were required to experimentally determine velocity as velocity is calculated by dividing the change in time over total distance. Since this experiment resembled a projectile motion, initial velocity would be the velocity throughout the entire motion of the marble, and as a result horizontal distance at any angle divided by time would give the correct velocity. However in order to determine this experimental velocity three trials were conducted to observe the motion, distance and time the marble took to reach the ground. Once three experimental trials were complete an average distance and average time could be used to calculate this exit velocity.
