Friction characteristics: Static vs. Sliding, Area of Contact, Normal force, Speed (Block w/spring scale)

This device can use the spring scale or the force probe while being viewed on the screen with the software on the class computer. (I can set it up before class to view a graph of the friction force.)

Various aspects of friction can be shown:
[1] Statis vs. kinetic,
[2] Area of contact by laying the block on its wide base or smaller side,
[3] Speed of movement are the sam by pulling slow or fast,
[4] Friction depends on weight by adding them to the block.
