Thread: Perpetual motion machines

All these machines are transforming an energy- Gravity- into motion.

As long as this force is greater than the energy generated by the frictions of the moving parts the machine will keep on moving.

The principle of Lavoisier in chemistry also applies here "nothing is gained or lost, merely transformed"

Yes but they are by no means 'perpetual motion' machines. Friction and air drag will eventually stop them moving without fail.

entropy prevents a perpetual motion machine
