An unchanging speed is constant.
Acceleration is the change in an ogjects speed or a change in an objects direction of motion or both of these. If instead of speed you use the word velocity , which is both an object's speed and its direction of motion, then you could say "acceleration is the change in an objects velocity" and that would cover all the possibilities in one statement.
(in the US) This answer can change from municipality to municipality, but GENERALLY it is safe to say that it is 25 MPH.
change in speed is acceleration. change in speed is the slope of the speed versus time graph, or the derivative of such.

The object will maintain its speed and direction or the object will not change its speed or direction.
Motion occurs when there is speed. A change of speed is not required.
No, the Earth's rate of speed in its orbit around the sun remains relatively constant. However, the Earth's distance from the sun varies slightly throughout the year, affecting its orbital speed slightly.
due to acceleration the speed and velocity will change automatically
Change in speed (more precisely change in velocity) is called acceleration.
The voltage and frequency ARE the output of the generator. If you change the fuel to the generator, it will change speed, and the voltage will change. Less fuel = less speed = lower frequency = lower voltage.

Temperature can change the speed of some reactions.
