Measure gravity in real time

The Free Fall Demo Kit is a focused kinematics lab system designed to measure acceleration due to gravity through direct velocity data. Using two BeeSpi v Standalone Photogates, a vertical drop tube, and a steel ball bearing, students can record precise velocities at known height to determine gravitational acceleration (g). With minimal setup and repeatable results, this kit makes free fall measurable and data-driven in any physics classroom.

The Free Fall Demo Kit is included in the Complete Kinematics Kit, a comprehensive system for studying motion in one and two dimensions with shared, coordinated equipment.

Why Teachers Love It

• Direct Measurement of Acceleration Due to Gravity – Students collect real-time velocity data to calculate gravitational acceleration ( g ) through authentic experimentation.

• Simple Setup, Reliable Results – The drop tube ensures a clean vertical path, while the BeeSpi photogates provide accurate, repeatable velocity measurements.

• Clear Data for Graphing & Analysis – Supports velocity calculations, acceleration determination, and position–time and velocity–time graph construction.
