Description

Rest the tube on the lecture table. Lift one end to obtain constant acceleration. Lift one end of the tube and immediately place it back on the table to obtain constant velocity. Rolling a sphere down a uniform incline led Galileo to some of the earliest conclusions regarding motion with a constant acceleration and to information regarding the acceleration of gravity on the earth.◙
