Cobra DigiMotion Basis Set

Article no: 12975-77

Function and Applications

TheCobra DigiMotion Basic Set is an experimental kit for conducting 6 experiments on various topics in kinematics and dynamics. It is designed for use in middle and high school physics lessons and is intended for the study of two-dimensional plane motion. The set consists of an electromagnetic board and a signal source. It is based on the principle of electromagnetic positioning and allows continuous measurement of the signal source’s position at any time within the effective measurement area. Through high-frequency data acquisition, the trajectory of objects in two-dimensional motion can be displayed using the included free software. Velocity and acceleration can be calculated from the position data at any moment. Measurements are performed simultaneously with the visualization of motion phenomena, making physical laws clearly visible. The Basic Set can be upgraded to an Expert Set, allowing three additional experiments to be conducted.

Benefits 

  • High measurement accuracy through electromagnetic positioning
  • Clear and illustrative presentation of physical laws through simultaneous measurement and visualization of motion phenomena
