Accelerometer, Large

This transparent structure is used to demonstrate Newton’s Second Law. The accelerometer is filled with a colored liquid, the surface of which responds to inertial forces. When it is accelerated the slope of the liquid surface is a measure of the acceleration. The grid lines are marked from 1 to 12 centimeters in either horizontal direction from the centerline and from 0 to 6 centimeters in either vertical direction from the centerline. This accelerometer can be used on carts or turntables or by the students in walking or running to demonstrate the various effects of accelerated or uniform motion.

The base has been designed so that the unit mounts securely on a dynamics cart and will not slide during rapid accelerations.
