It is the propeller.
Longitudinal aircraft dynamics variables are (small) deviations from operating point or trim conditions state (components): u: velocity of aircraft along body axis v: velocity of aircraft perpendicular to body axis (down is positive) : angle between body axis and horizontal (up is positive) q : angular velocity of aircraft (pitch rate)
A radar scope is a display device used in radar systems to visualize the information collected by the radar. It shows the location, distance, and movement of objects, such as aircraft or weather patterns, by translating radar signals into graphical representations. Radar scopes are commonly found in air traffic control, meteorology, and maritime navigation, providing operators with critical real-time data for decision-making. The visual output typically includes blips or markers representing detected targets, along with additional information like speed and direction.
It is pretty close to 0. I am sitting at a desk. However, I am also sitting on the planet earth which is revolving on its axis as well as rotating around the sun (approximately); the sun is rotating along with our arm of the Milky Way Galaxy, the Milky Way Galaxy is moving through space towards the Andromeda Galaxy and our local cluster is headed towards ... . My head starts spinning when I think of all the calculations required. Besides, what fixed frame of reference can I use to measure all these movements?
The Egyptian irrigation device, commonly known as the shaduf, is a hand-operated device used to lift water from a river or canal to irrigate fields. It consists of a long pole with a bucket on one end and a counterweight on the other, allowing farmers to efficiently raise water for agricultural purposes. This simple yet effective tool played a crucial role in ancient Egyptian agriculture, enabling the cultivation of crops in arid regions along the Nile River.
A potentiometer is typically made by using a resistive material, such as carbon, conductive plastic, or wire, which is arranged in a specific configuration along a track. A sliding contact, or wiper, moves along this resistive path to create an adjustable voltage divider. The assembly is often encased in a housing to protect the components and ensure smooth operation. Finally, terminals are added for electrical connections to complete the device.

The rotating device that propels a ship is called a "propeller," while in aircraft, it is also referred to as a "propeller," or in some cases, "turbofan" or "jet engine" for jet-powered aircraft. Propellers work by converting rotational motion into thrust, allowing vessels to move through water or air.

A screw is a simple machine that can convert rotational motion into linear motion. By rotating the screw, the inclined plane wrapped around the cylinder pushes objects along the screw's axis.
Friction - the force that makes it difficult for one object to slide along the surface of another
Car engines burn fuel in cylinders. When the fuel burns the air in the cylinders expands. The expanding air pushes down on a piston. The piston pushes down on a crankshaft. Then the piston comes back up. The piston going down and up makes the crankshaft rotate. This rotating motion is transferred to the wheels of the car. That pushes the car along. Thus the fuel burning in the cylinders pushes the pistons. Without Petrol to burn in the cylinders, the pistons would not push the crankshaft. It would not make the wheels move.

Gravity. And, we are moving right along with the surface.
