A body supported in such a platformgradually acquires tangential motion in moving toward thecircumference, and gradually loses tangential motion in movingtoward the center of rotation. Thus we may, if suitable meansare provided, get onto a revolving circular platform near thecenter of rotation without material disturbance to ones balance,and then by moving away from the center gradually and im-. ?»; ^^^3
