Purpose To illustrate the concepts of angular momentum and gravity. Parts The system of masses and pulleys is found on shelf D2 Set up Clamp system down on table. Thread attached string through pulley. Attach weight if desired. … Continue reading »
Purpose To illustrate that all objects in vacuum accelerate at the same rate under the influence of gravity (assuming the objects are, of course, sufficiently close together and acted upon by the same gravitational field). Parts Glass tube containing light and heavy object Air pump… Continue reading »

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 »
Purpose The feather and penny demonstration shows how air resistance affects falling objects. A penny and feather are in a tube, and when the tube is flipped, the feather takes more time to fall than the penny. But when the air is evacuated from the tube, both fall in the… 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 »
