This kit permits the swinging of a mass in a circular orbit under controlled conditions. Excellent accuracy can be obtained for mechanical experiments on circular motion. Measurements are made on orbit diameter, mass of the projectile and revolutions per minute.

Runs from a transformer or low voltage power supply from 8 to 12V AC or DC (NOT INCLUDED).

Motor and disc, mounted on support tube with cable and banana plugs. This motor unit is complete with its electronic speed controller to adjust and maintain small but steady rotational power to maintain the circular motion of the masses.

Apparatus also includes: • 3 x Special rubber masses, approx. 20mm diam x 4g, 25mm diam x 8g, 32mm diam x 16g, with measurement reference line, mass in grams marked on each and loop for attachment to light chain or cord; • 3 x Pieces of very light alloy chain cut to different lengths; • 4 x Metal clips to connect each chain to a mass and the motor disc; • 1 x Set of experiment notes (by Bruce Saunders).

Retort stand not included.

Genuine IEC product.
