Hands-On Experiences with Buoyant-Less Water
Slisko, Josip; Planinsic, Gorazd
Physics Education, v45 n3 p292-296 May 2010
The phenomenon of weightlessness is known to students thanks to videos of amazing things astronauts do in spaceships orbiting the Earth. In this article we propose two hands-on activities which give students opportunities to infer by themselves the absence of buoyant force in a gravity accelerated system. The system is a free-falling or vertically tossed bottle filled with water with a small, inflated balloon attached to the bottom by a spring. Practical hints on how to make efficient demonstration experiments are added. (Contains 4 figures.)
