Blimps use fuel efficiently because their engines provide only forward motion.

They can be used to provide limited motion sensing functionality.

This provides more precise motion of the stage.

This in turn made it a simple matter to adapt Watt's engine to provide rotary motion.

The actuator provides mechanical motion in response to an electrical stimulus.

It may provide rotary motion, linear motion, or a combination of both.

In an outside setting, wind or animals provide sufficient motion to produce commercially viable crops.

Propellers, commonly referred to as screws, cut through the water and provide forward or reverse motion.

The needle rod is constrained to provide only motion in the vertical direction.
