The purpose of this experiment was to design a projectile launcher that utilized spring power (obeys Hooke's law), to calculate the theoretical distance that would be traveled when a 65g spherical projectile is launched and compare it to experimental data. The theoretical calculations for the built launcher stated that the 65g projectile would travel a horizontal distance of 5.31m. This theoretical value was moderately met with 20.0% discrepancy at a mean distance of 4.23m over a series of three trials. The consistency over the three trials, represented with a standard deviation value of 0.115, proves a precision in the launcher's function.
