DESCRIPTION: The subject walks along a line with his/her arm straight out holding a ball. As the subject passes a bucket, where must she/he release the ball so that it will fall into the bucket?
SUGGESTIONS: This experiment is described in a reference paper on the relation between development of physical intuition in children and their understanding of the laws of motion.
