Using the Interactive

The Atwood's Machine Interactive is shown in the iFrame below. There is a small hot spot in the top-left corner. Clicking/tapping the hot spot opens the Interactive in full-screen mode. Use the Escape key on a keyboard (or comparable method) to exit from full-screen mode.

There is a second hot-spot in the lower-right corner of the iFrame. Dragging this hot-spot allows you to change the size of iFrame to whatever dimensions you prefer.

Using the Interactive

This Interactive will open in a separate browser window on your device. Click the Launch Tool button to open the Interactive. Close the window to return to this page.

Atwood's machine, showing energy bar graphs

Mass of block 1 (on the left)

Mass of block 2 (on the right)

The simulation shows the flow of energy for an Atwood's machine, which is simply two blocks connected by a string passing over a pulley. Block 1 is the blue block on the left, and block 2 is the red block on the right. You can view the energy from seven different perspectives, ranging from defining the system to be the Earth and the two blocks and the pulley, to just one of the blocks or just the pulley.

Note that the simulation uses 10.0 m/s/s for g.

See if you can make sense of all the different perspectives on energy. Note that, because all parts of the system start from rest, the initial kinetic energies are not shown (all are zero). In some views, you see the work done by gravity on block 1 and/or block 2, or the work done by tension on block 1, block 2, or on the pulley. The labels are either above or below the bars, not beside them. U is gravitational potential energy, W is work, and K is kinetic energy.

Example - Find Tension, and acceleration if  k =.11: 32.0 kg 5.0 kg Step 2 - Calculate or express = ma for every mass object For the 5.0 kg mass, the tension T is up (-) T (-) +49 N The weight of 5*9.8 = 49 N is down (+): And our formula becomes: 49 N - T = (5.0 kg)a Step 1 - guess direction of + acceleration (This becomes the + direction for each mass) +a
