Other measurements used which affected the range

This preview shows page 3 out of 3 pages.

measurements used which affected the range predictions include variations in the speed measurement, which is affected by the measurement of the Photogate spacing. As well as possible error in the table height that was calculated, which could be different from the actual height. Additional errors include the fact that the table may not have been level, causing the ball to not have a horizontal starting position yand the ramp may not have been perfectly lined up with the expected impact points marked with tape on the floor. Air friction is not accounted for in this experiment, but air friction cause the ball tofall short of the predicted impact points. In the lab motion was analyzed using two different experimental procedures. The vertical and horizontal motion of a ball tossed over a meter stick was studied and the acceleration and horizontal speed were calculated.Secondly, the velocity of a ball rolling down a ramp was calculated using Photogates and the impact range of the ball on the floor was wrongly predicted using two-dimensional kinematics.
