Why does it take so long for airplane propellers to reach their full rotational speed?
Inertia, resistance to motion from a standing start is the pat answer. also if one is talking about modern (Warll-to date) propeller driven craft they have to be run-up gradually as various preventive maintenance tasks are performed such as testing mags (Magnetos), running the shift control through various prop pitches, and so on all this is done in stages to avoid sudden failures/and or catch trouble spots in time.Engine failure at any portion of the flight cycle is serious and on take-off or after take-off can be catastrophic . hence- the methodic run-in procedure.

What is the relationship between rotational speed and linear speed?
(linear speed) = (rotational speed) x (radius or distance from the center) To use consistent measures, use radians/second for rotational speed, meters for the radius, and meters/second for the linear speed. If you know rotational speed in some other unit - for example, rpm (rotations per minute) - convert to radians per second first.
When the airplane experiences a tailwind are the forces added or subtracted?
When an airplane experiences a tailwind, the forces are added. The tailwind helps push the airplane forward, increasing its ground speed, which can reduce the time needed to reach its destination.
How is rotational speed affected by the radius?
Rotational speed is inversely proportional to the radius. A smaller radius will result in higher rotational speed, while a larger radius will result in lower rotational speed. This relationship is described by the equation v = rω, where v is linear speed, r is radius, and ω is angular velocity.
Which is not part of the equation for angular momentum?
Rotational speed. Rotational speed is typically used to calculate rotational kinetic energy rather than angular momentum, which is determined by rotational inertia and angular velocity.
When the rotational speed of a rotating system doubles its angular momentum?
When the rotational speed of a rotating system doubles, its angular momentum also doubles. This is because angular momentum is directly proportional to both the mass and the rotational speed of the system. Therefore, if the rotational speed doubles, the angular momentum will also double.
Is the airplane takeoff controlled by the propellers or the wheels?
The aeroplane takeoff is controlled by the engine speed and the elevators.
How does linear speed change as rotational speed changes?
At any distance from the axis of rotation, the linear speed of an object is directly proportional to the rotational speed. If the linear speed increases, the rotational speed also increases.
What are the units for rotational speed?
the units for rotational speed are radians / sec or degrees / sec
What is the highest speed a small airplane can go?
This question can't really be answered with a single speed. Each airplane is different to another and is able to reach different speeds. A small business jet like for instance the Cessna Citation X is able to reach speeds up to Mach 0.95 (that is 0.95 times the speed of sound).
How does an airplane reach its fastest speed?
Augmented maximum mechanism or in simple term after burner is incorporated to high speeds.

What is an input speed sensor on a 1999 Chrysler lhs?
It is a sensor on the transmission that reads the rotational speed of the input shaft.It is a sensor on the transmission that reads the rotational speed of the input shaft.

Rotational speed. Rotational speed is typically used to calculate rotational kinetic energy rather than angular momentum, which is determined by rotational inertia and angular velocity.
Hard disk has a rotation speed of 7200RPM then the latency time is?
it depends on more then rotational speed. The Rotational speed and latency time is related as follows: Latency time = (1/((Rotational Speed in RPM)/60)) * 0.5 * 1000 milli seconds
