Increase the versatility of your kinematics experiments with this unique demonstrator. With seven different launch angles from 0 to 90°, this device allows for both horizontal and variable angle launching positions. Its fully enclosed spring launching mechanism features four settings and enables you to choose from four different launch positions, released by means of a simple arm release mechanism. Launcher is mounted on a board with launch angles clearly marked, and can be fitted with photogates. We recommend using the CENCO Photogate System, WLS-1800-93. Includes a bench top clamp. Screen size: 30 x 20cm.
