Well if you're thinking electricity, magnetism, light, sound, optics,
nuclear, nasty maths – Physics is likely not for you. But for setting
up sandpit experiments in motion, forces, rotation, torque, work/
energy, momentum, gravity, mechanics/engineering... Have you tried
building actual 'stuff' with a goal yet? Think 'mousetrap' and wire up
some marvellous goal oriented contraptions for say:

1) Sorting different sized balls in to two buckets, large and small
(with no jams).
2) A cyclic mechanism for lifting balls from the bottom of the screen
to the top, again and again.
3) Try dropping 2 different mass objects at the same time.
4) Experiment with pendulums of different lengths and masses.
5) Try building a mechanical binary clock.
6) Convert rotation into parallel motion using pistons.
7) Experiment with touching one motorised circle against one pinned
circle of various sizes.
8) Try building a rag-doll puppet and make it dance in a convincing way.
9) Use just links and circles to make a structurally sound Eiffel Tower.
10) Try building a ratchet
11) Try building an analogue click face where the min hand goes around
60 times for each hour.
...

P.S. Keep in mind that once we have Journal state saving, and then a
MIME type for those entries, we will be able to upload and share all
kind's of example contraptions and demonstrations to a web server or
directly between machines (via Journal sharing).
