Introduction The falling drops demonstration is a way for students to observe the motion of an object under a constant acceleration (in this case, from gravity). By timing the flashing of a strobe light to sync with a water pump, fluorescing falling water drops appear to freeze midair. Students can… Continue reading »
Introduction Final set up of Galileo drop To observe the displacement of an object at constant acceleration, a cart is sent down an inclined air track, with flags or sticky notes marking positions on the track. These positions correspond to the increasing distances traveled over equal time intervals. A… Continue reading »
