Product Description

By: The Flinn Staff

Finally! An inexpensive Atwood's machine that successfully measures the acceleration due to gravity. It's also a perfect device to effectively teach Newton's second law of motion, friction, rotational inertia and measurement accuracy. Simply hang two slightly different masses over the Atwood's machine's pulleys and time how long it takes the heavier mass to fall a certain distance. The slower rate of descent makes it much easier to time the falling mass than an ordinary gravity drop experiment. No need for a photogate timer. A simple equation allows you to calculate the acceleration due to gravity from time and distance of descent. Students can also easily measure the amount of friction to achieve more accurate results. Pulley cord and detailed instructions are provided. Requires two slotted weight hangers, slotted weight set, stop watch, support stand, and clamp holder.

Clamp Holder
Clamp holder with thumbscrews for attaching extension clamps or other hardware to supports. Will fit rods up to ½" in diameter.
Slotted Weight Set, Economy Choice
Polished brass weights are slotted and supplied on a metal rack. Includes 8 weights—one each of 10 g, 50 g, 100 g, 500 g, and two each of 20 g, 200 g.
Hanger, Slotted Weights
Hanger has a mass of exactly 50 grams. Top hook allows for easy use.
Timer, Stopwatch, Flinn
Electronic, water-resistant stopwatch with a quartz crystal offers remarkable accuracy many times superior to mechanical stopwatches. Stopwatch has 24-hour range. A liquid crystal display (LCD) provides great readability. Time range provided on the...
