Unformatted text preview: cases of these two dimensions (X and Y). Marbles were released off ramps and their landing positions were then recorded. The x and y components are separately calculated since momentum is scalar. We did not need to calculate the y components since its total would be zero; instead we calculated only the x components. VII. Error Analysis % Error = Expected  Actual Actual = .36 3 − .355 .355 ≈ 2.35% Since the marbles landed at locations that were only relatively consistent (due to factors such as air resistance, friction, tiny movements of the ramp), the actual landed locations were only an estimate....
