No.
When an object accelerates its velocity is changing.
As velocity is defined as speed with direction, its velocity changes if
either the speed or the direction of travel changes.
As its velocity is changing it is technically accelerating (or possibly 'decelerating'
if you are an American)
The speed of the object will increase.
The speed of the object will increase.
Acceleration is the rate of change of velocity over time, so velocity must always be changing if the object is accelerating. HOWEVER, you said speed which means only magnitude, not direction. If you stay the same speed, but change direction then you are accelerating. Simple answer: when you are going the same speed in a circle - velocity changes, therefore acceleration changes.
Yes. 'Acceleration' means either speed or direction is changing. If direction is changing,then there is acceleration, even if speed is constant.
The rate at which the speed or direction of its motion is changing.
When an object accelerates it can change its speed or direction of motion. When it accelerates without changing its direction of motion, it can cover any distance in less time.
The speed of the object will increase.
The speed of the object will increase.
The speed of the object will increase.
It accelerates as long as the force is applied, and after that it continues at a uniform speed and direction.

An object is accelerating if any of these things are happening . . .-- its speed is increasing-- its speed is decreasing-- its direction is changing.The object may be accelerating even if its speed isn't changing.Acceleration does not mean "speeding up".
Acceleration is zero when the object's speed and direction stop changing.
