==== Exercise 5: Block for changing direction when moving objects ====

This exercise is carried out at floor level. The aim is to move an object any distance across the floor. The exercise begins by first determining the movement to be achieved. It is optional how and where blocks are arranged and how long pull ropes are used.

In a second step, move the object in two stages, each in a different direction. In this step several blocks and ropes can be used.

Observe:

* What has been prioritised in the arrangement of the blocks - gaining power or high speed?
* Has the intention been to hide the arrangement of blocks and ropes or has it been allowed to show?
* For complex movement - how many blocks and ropes have been used?
* Are there alternative solutions to the problem?
