[Phys-L] A(g) of a pendulum



Before I trouble G. Galilei-ing, any one run a pendulum in reduced g? e.g. a cart falling down a ramp.

The suspension an RMS** and the acceleration measured by a linearized RMS using a thread loop attached to the cart.

** Rotary Motion Detector (optical encoder)

bc probably will do it anyway; has all the app.
