underwhelming
Wm from Bellevue
This item is sturdy and very well constructed. However, for some reason the manufacturers decided to use stippled paint to coat the entire surface, including the rail surfaces. The bumps in the paint cause a huge rolling resistance, so the oscillating motion quickly damps to a standstill. I will smooth the rails down with emery cloth and steel wool to hopefully give more sustained oscillations.
1 customer reviewsThe stringless pendulum demonstrates simple harmonic motion. Students and other observers will witness the period of an oscillating body from a different perspective than the standard string and ball. The period of the steel ball can be measured and the distance to a focal point can be calculated to compare the demonstration to a classic pendulum.
Includes:
- One stringless pendulum track
- two solid steel balls, 19mm
