An object moving at constant speed in a circle. Acceleration is rate of change of velocity, as velocity is speed in a certain direction, when moving in a circle an object's velocity is constantly changing, as its velocity is changing it is accelerating.

Describe a situation in which an object accelerates without changing speed?
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.
A situation in which you can accelerate even though you speed does not change?
"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 constantacceleration.
What is a change in speed and direction called?
If an object is in motion, we apply the term speed to the distance (displacement) it achieves for a given unit of time. If we take speed and add a direction vector, as is asked here, we are talking about the velocity of the object.
Does velocity describe both speed and acceleration?
No. Velocity describes a speed and a direction. Acceleration, on the other hand, is the rate of change of velocity (in symbols: dv/dt); in other words, how fast does the velocity change.
Why an object moving in a circular path at a constant speed is undergoing acceleration and has a force excert on it?
-- An object with no net force on it continues moving at constant speed in a straight line.If it's not moving in a straight line, then there must be net force acting on it.-- "Acceleration" is the word for the situation where either speed or direction of motion changes.Even if speed is constant, acceleration is present if the direction is changing.
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.
What changes in motion cause acceleration?
"Acceleration" is the term used to describe motion whose speed, or direction, or both, are changing.

Is Acceleration is a rate that can describe how speed or direction is changing?
Acceleration is a change in velocity. Velocity is defined as the speed of an object in a specific direction. It is a vector quantity. Thus acceleration could be a rate of change of speed, velocity or both. In addition, acceration can be negative. In physics terms, there is no such thing as "Deceleration". Any change is considered to be acceleration.

The relationship of speed and acceleration?
Acceleration is the time rate of change of speed. Acceleration = speed/time.
How would you describe the values for acceleration?
positive or negative change of velocity or change of direction of the speed vector

Is acceleration the same as speed?
Acceleration is the rate that speed changes.
