change in speed is acceleration. change in speed is the slope of the speed versus time graph, or the derivative of such.
If an unbalanced force acts on an object, the object will experience acceleration. The speed of the object will change in the direction of the force that is applied to it.
Acceleration is a measure of how quickly the speed of an object changes over time, not the speed itself. Speed refers to the rate at which an object covers distance, while acceleration refers to how the speed of the object changes. So, acceleration is not a kind of speed, but rather a measure of how speed changes.
Yes, a change in speed of an object always indicates a change in speed. Speed is a scalar quantity that represents how fast an object is moving without specifying the direction, so any change in the speed of an object indicates that it is either speeding up or slowing down.
A change in speed is a change in velocity - so, a change in speed is an example of acceleration! Acceleration may be positive or negative. Negative acceleration is sometimes called deceleration. When a force acts on an object; it may change the object's acceleration (speed, direction, or both).

invariable speed or constant speed
Motion occurs when there is speed. A change of speed is not required.
An unchanging speed is constant.
It is constant speed.

Speed is the rate of motion usually expressed as distance traveled per unit of time.Velocity is the rate of change of position. Both speed and direction are required. Acceleration is the rate of change in velocity. In common speech, acceleration is only for an increase in speed; a decrease in speed is deceleration. In physics, any increase or decrease in speed or change of direction is referred to as acceleration.
