1. What is the reason for seeing curves going out on the right of the used position, velocity plot, and reentering from the left?
A the pendulum passes the vertical hanging position
B the pendulum overturns
2. A periodic motion is much simpler than a chaotic one. What would one see if a periodic motion (e.g., a pendulum in vacuum) is sampled as above, that is points are taken with the period of the motion?
A as a single point
B as a set of a few points
3. How would a periodic motion (e.g., a pendulum in vacuum) appear in the position, velocity plot as time goes on?
A as a single curve
B as a coil
4. The structure within chaos is reflected by the appearance of a fractal pattern. Can any type of fractals (e.g., the one describing the coastline of an island) be related to chaos?
A yes
B no
5. Can a predictable motion be associated with a fractal structure?
6. Can a motion associated with a fractal structure be periodic?
