Atwood-Machine

An Atwood machine is a common classroom demonstration used to illustrate principles of physics, specifically mechanics.

It was invented in 1784 by Rev. George Atwood. It demonstrates principles of uniform acceleration by objects.

Directions: 1. Draw a picture of the Atwood machine in your notes. Copy from page 56 in the text.

2. Draw a chart in your notebook to record your observations. It should look like this:
 * **Trial** || **Mass 1** || **Mass 2** || **Acceleration** || **Observations** ||
 * **1** ||  ||   ||   ||   ||
 * **2** ||  ||   ||   ||   ||
 * **3** ||  ||   ||   ||   ||

3. Visit the [|Atwood Machine] website to do an experiment. * Set to NO FRICTION > > 4. Record your observations in the table in your notebook.
 * 1) Make Mass 1 higher than Mass 2. Hit GO.
 * 1) Make Mass 1 lower than Mass 2. Hit GO.
 * 1) Make Mass 1 equal to Mass 2. Hit GO.

5. Complete the Reflect & Connect question #1 from the text.

6. Define: Static and Dynamic on your vocabulary worksheet.
