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
