Trajectory Apparatus

This unique low-cost trajectory apparatus allows the students to study the trajectory of a projectile. A steel ball launches from a ramp and collides with the target plate that is equipped with marking paper to record the point of contact manually. Move the target plate to different positions and the exercise is to plot the full trajectory of the ball. The kit consists of a wooden plotting board, two wooden supports, one steel ball, one cello tape roll, four graph papers and four marking papers. The apparatus is provided with full instructions.
