Freefall Apparatus

New Design for More Accuracy

Students can observe and measure the acceleration of a falling object. The unique drop and catch design, when used with the Fun Stand, allows an object to fall directly through a pair of photogates. The exact value for gravity can then be calculated for your local geographic area. The two included marbles have different masses, so the experiment can be repeated mutliple times to illustrate the universal effect of gravity.

Ordering information: Requires the Fun Stand and Photogate System. Includes a wooden dropping device, catching device, two marbles of different mass, two mounting screws, instructions, and activity guide.

Caution: WARNING: CHOKING HAZARD–Small Parts. Not for children under 3 yrs.
