Preparation: Force/Tension/Explain It.

On the next page you can access the five simulations from the session named above.

• Vertical Rope. Tension at different points in a massless rope. The rope is suspended from a ceiling and holds up a crate of variable mass.
• Vertical Massive Rope. Tension at different points in a massive rope suspended from a ceiling. The mass of the rope can be varied.
• Tug of War. Tension at different points in a horizontal stationary rope that has several forces applied to it at either end.
• Horizontal Rope. Tension at different points in a horizontal stationary rope. The rope has a single force applied to it at either end whose magnitude can be varied.
• Train Demo. The tensions in the strings connecting three blocks pulled on a horizontal surface by an applied force. The system can have friction. The applied force, the masses of the blocks, and the friction coefficients can be varied.
