This experiment, created by the students of the class, went relatively well. In this lab, we teste the theory of the conservation of energy. The kinetic energy at the bottom of the ramp should equal the potential energy at the top of the ramp without regard to the path taken. Thus, for method 1, the equations for kinetic energy (1/2mv²) and potential gravitational energy (U_g=mgh) were used. For the second method, the concepts and formulas for constant acceleration was used in conjunction with the equation for kinetic energy. The equation, d_y=v_i t+1/2 at², was used to find the time of flight of the marble after it left the ramp. The time was used in the equation, d=vt, to find the initial horizontal velocity. This was used in the kinetic
