A device allowing only one-way motion is called a "check valve." It is designed to allow fluid or gas to flow in one direction only, preventing backflow or reverse flow in pipelines or systems.
An object that never stops moving is called a perpetual motion machine. This concept refers to a hypothetical device that can continue to operate indefinitely without any external source of energy. Perpetual motion machines are considered impossible to create due to the laws of thermodynamics, which state that energy cannot be created or destroyed, only transferred or converted.
The usual name for a force that can't produce motion but can only change the motion of an object is called a frictional force. Friction acts in the opposite direction to the motion of an object and resists its movement.
A device that receives only one plug is a single-outlet electrical device.
All objects resist a change in motion. That is Newton's first law of motion. It requires only that the object have mass. An object that is not acted on by an external force will continue in it previous state of straight line motion. The property that all object have that resists a change in motion is called inertia. The quantitative measure of the inertia of a body is called its mass. This answer applies to movement through space. There is a similar explanation for rotational motion.
Motion under the influence of gravity alone is called free fall. In free fall, an object is only acted upon by the force of gravity, causing it to accelerate towards the Earth at a constant rate.
If it is only spinning then this is called gyroscopic motion.
A device which operates(or function) only in one direction is called unidirectional (or unipolar) device
As an educator with technical knowledge, I view the screw as a highly efficient lifting device due to its mechanical advantage gained from the pitch of its threads. The screw converts rotational motion into linear motion, allowing for controlled and precise lifting operations. Its design provides stability and can handle heavy loads with minimal effort. Overall, the screw is a versatile and reliable lifting mechanism widely used in various industries.

It was called the Television but when first coined it was called the "Cathode tube" which as we know was actually only part of the device

Some devices have the receiver and transmitter built into the same device. Some devices use only a detector and register changes in emitted IR "patterns" (for example) to infer motion.
if an object moves along a circular path, the only change in its velocity is due to the change in the direction of the motion. The motion of the object moving along the circular path is, which is a uniform circular motion, is therefore an accelerated motion:):):):/
Not all mobile devices are called smart phones... Only Cellular Phones with outstanding capabilities are called Smart Phones.
It's called a Ratchet
Such waves are called Longitudinal Waves.
This is called rationing
