Demo 02-05 Air Table Parabolas

Pucks are projected at an uphill angle along a tilted air table. The motion of the puck then is described by a constant velocity in the direction perpendicular to the tilt and a constant acceleration in the direction of the tilt. As in the case of a standard projectile, this leads to motion of the pucks along parabolic paths.The video shows three projectile paths, with the air table tilted at 3?, 6?, and 9?, respectively. The position of the puck at a series of equal time intervals is marked on the screen so that the shape of the parabolas can be studied and the vertical acceleration and the horizontal velocity can be experimentally obtained. The parabola for the case of 6? is shown in Figure 1
