- A mass on a string hanging over a pulley holds a glider on an incline or accelerates it.
- Stop the glider before it reaches the end of the track.
- Gliders differ in mass by a factor of 2.
(use 10-200 g masses only, elevate one end with 10 x 10 cm block)
(50 g holds glider on 1.2 m track elevated 10 cm)
(put tarp on floor to catch hanging mass, remove pulley during transport) |
