It travels in a circular motion.
Perpetual motion machines do not exist. There is no machine that will keep on moving by itself without any added power. Windmills are driven by the wind. When the wind stops blowing, the windmill stops turning.
Wind acting on the blades of a windmill causes it to spin around it's axis. This spinning motion is the conversion of mechanical, wind, energy to torque, mechanical rotational force. This drives a shaft for a pump or a generator.
wind makes the mill spin wich motion activates the machinery that sends electricity or other means of energy.
The ways to harness energy vary as broadly as the sources that are being tapped. There are a lot of energy sources, and it would be wise to investigate a bit more by asking some more questions here and narrowing the focus of them.
pls adv the dimension of windmill
The famous technique where you swing you arms in windmill like motion is called the windmill.
Perpetual motion machines do not exist. There is no machine that will keep on moving by itself without any added power. Windmills are driven by the wind. When the wind stops blowing, the windmill stops turning.
The principle of lift is well-illustrated by the motion it causes.

All. First (No wind, no motion),Second (F=ma) and the Third Action and Reaction.

they are mad because they built the windmill. During the battle of the windmill they have to rebuild the windmill
An oribit.
any common electrical generator ... windmill, hydro, bicycle wheel, steam turbine, etc.
