It's used for the speedometer and the cars ECU (computer).
It tells both how fast your going.
Sure, why not.
Yes. Kinetic energy is a function of both speed and mass.
Acceleration is the rate of change of the velocity (speed) of an object. Acceleration is the derivative of the speed vs. time function.
If the increase in speed is uniform, this means that the slope of the function of speed over time is constant. This means that acceleration is constant.
The question is poorly put. Perhaps your underlying concern is best addressed by explaining what 'speed' really means. 'Speed', by definition, is the absolute value of the velocity vector. The velocity is in turn the derivative of the vector (function) describing the object's position as a function of time. This is why we can have a constant speed even when the velocity is always changing, as happens with circular motion with the velocity always directed towards the center of the circle. So if the speed is non-zero, then there must be some motion. Is that what you mean by "show motion"?
to speed off energy
Sure, why not.
the function of a tail is to lift its body and to increase the speed of flight
The function of a stimulant is to speed up your metabolism which stimulates your heart and other muscles.
false
This controls the engine speed
it is a speed limiter of engine...control speed respect to load....
Yes. Kinetic energy is a function of both speed and mass.
A catalyst.
controlled the speed engine
You will not be able to turn .
