Mokomoji troleibusų trasa
Gelsonlab HSPD-100 Mokomoji troleibusų trasa for Physics experiment
Mokomoji troleibusų trasa and other accessory for investigating linear motion, Three adjustable point supports for setting horizontal alignment. Trolley moves with minimum friction on track , by add spring bumper or ‘Velcro ‘bumper to have elastic or inelastic collisions, add flag to trolley to measure timing by “smart timer” examine the regular movement and movements with uniform acceleration test the conservation of energy ( can add weight set to increase the mass of trolley )
