"Acceleration" means a change of speed or direction of motion, or both.
If you change direction ... like turning a corner ... then there is acceleration,
even though your speed is constant.
Anything traveling on a circular track, even at a constant speed, has constant
acceleration.

Is there a change of short circuit even you off the appliances?
yes
Why do propellers blades vary?
Another word for a ships propeller is a 'screw'. Modern ship propellers have variable pitch blades, which means the blades can change angles (even to a 'reverse angle). The pitch is changed by changing hydraulic pressure in the propeller. One reason: You can change the pitch a lot faster than you can change the speed of the engine, since the heavy shaft and propellers have momentum, this is especially important, if you need to go 'full reverse' to avoid collision. If you did not have variable pitch blades, the shaft would have to come to a complete stop before it could reverse direction of rotation. Another reason, the engine can be run at an 'optimum speed' for fuel efficiency, and the blade pitch adjusted if you need to adjust speed.
Normally a high current flows through a short circuit even if there is no change to the voltage. Why is this?
A high current flows through a short circuit even if there is no voltage change because the resistance across the short circuit is zero.
What is speed multiplier?
a speed multiplier is an object which moves at high speed and multiplies that to create more speed with an object it is trying to move. an example is hitting a tennis ball with a tennis raquet - you swing your arm/hand at a short distance at high speed and great effort so travels a great distance at an even higher speed. the distance the ball moves is large so the force by your arm/hand is small. hope this helps! :)speed multiplier- machine that requires a small movement of an effort to produce a large movement of a load, such as a third class lever.source: Pearson Science S.B
Why a machine should run with synchronous speed?
A synchronous motor is not self starting.However when it is provided with some prime mover ,which rotates it up to 80% of sync. speed,then it continues to rotate at sync.speed even after prime mover is removed.It happens so because rotor poles are locked with rotating magnetic field and hence the speed is always synchronous.
How can your speed accelerate even though your speed does not change?
Your speed can accelerate even though your speed does not change if you are changing direction or accelerating in a circular motion. In these cases, even though your speed remains constant, your velocity changes due to the change in direction, causing acceleration.
A situation when you can accelerate but the cars' speed doesn't change?
"Acceleration" means a change of speed or direction. If the direction of your motion changes, then there is acceleration, even if your speed doesn't change.
Decsribe a situation in which you can accelerate even though your speed doesn't change?

How does a skater not accelerate?
By not changing their speed. Technically, this means also not changing their velocity, which includes direction. So, you don't accelerate if you skate in a straight line at a constant speed. Otherwise, you are accelerating, even if your speed does not change.
How do you accelerate without changing speed?
To accelerate without changing speed, you can change direction. Acceleration is the rate of change of velocity, which includes speed and direction. For example, a car moving at a constant speed on a curved path is constantly changing direction and therefore accelerating, even though its speed remains constant.
How could an object accelerate was still traveling at a constant speed?
An object can accelerate while still traveling at a constant speed if it changes direction. Acceleration is the rate of change of velocity, so even if the speed remains constant, a change in direction would still require acceleration.
What acceleration of a car accelerate even thought your speed don't change?
If the car is moving at a constant speed but is changing direction, it is accelerating. Acceleration is change in velocity, and velocity includes magnitude (speed) and direction.
Why do you consider a moving object to accelerate even when it slows down or chnges direction without changing speeed?
Because that's the definition of "accelerate". "Accelerate" doesn't mean "speed up", although that's how everybody who rides in a car uses the word. "Accelerate" means "change the speed or the direction of motion, or both".
How can you accelerate if your speed does not change?
A change in the vector or direction that you are traveling is considered an acceleration; even if you don't change speed. This would be the case for going around in a merry-go-round, e.g. You are accelerating (changing direction), but the speed is constant (velocity is changing).
How can object accelerate when it does not change speed?
Let's review some terms before we tackle this one. Speed is displacement per unit of time. We know 60 miles per hour is a speed. Velocity is speed with a direction vector associated with it. We know 60 miles per hour east is velocity. Acceleration is a change in velocity. That means if an object changes its speed or its direction or both, it is accelerating.If an object has a given velocity and it slows down or speeds up, it is accelerated. But if the same object changes direction without a change in speed, it is still experiencing acceleration. A force had to act on the object to change its direction, even though its speed didn't change. Thus, an object can accelerate even though it does not change speed.
How do unbalanced forces change the speed?
Unbalanced forces can change the speed of an object by causing it to accelerate in the direction of the greater force. If the unbalanced force is in the direction of motion, the object will speed up. If it is in the opposite direction, the object will slow down or even come to a stop.
