Preparation: Energy/CM-Work Theorem/Explain It/.
The applet on Page 2 simulates the motion of a block on a horizontal surface. The block is subject to friction and to an applied force.
For detailed information on how to use the applet, please see Help, Assumptions, and ShowMe under Applet Help on the applet's Help menu.
The CM-work theorem is useful for understanding the motion of a block sliding on a horizontal surface. For suggestions on investigations possible with the applet, see Activities under Related Items.
