-introduction...
+A moving body would like to continue in a straight motion. If it is bound to by a string, or some other way it will move along a circular trajectory but it will pull the string with a centrifugal force. How large is this force? We will measure it using the force sensor in this exercise.

-description of the program
+The program slowly accelerates the rotating movement by increasing the motor power from 1 to 100. While accelerating, it is recording the actual power, the resulting motor speed and the force applied to the force sensor. Use the dumpdata.zip program from the pendulum exercise to extract the data, show them in a table and a chart. Measure the rotating arm length and the weight of the mass that is pulling the sensor.

+* Be careful when running the experiment, the rotating body accumulates a lot of energy! Use the bottom bricks to fix the model in between two tables.

+* Repeat the same experiment with different weight. You can also try to change the gear ratio at the bottom of the model to obtain different speeds.
