Preparation: Force/Newton's Sec'd Law/Explain It/Fletcher's Trolley.

The applet on Page 2 simulates a Fletcher's Trolley apparatus (a horizontally moving block connected via a pulley to a vertically moving block). The free-body diagrams for the two blocks and data on the system's acceleration and string tension can be displayed.

Detailed information on the applet and two lessons related to the applet are available under Applet Help on the applet's Help menu.
