Is it possible that there is a non-zero acceleration but with a speed of value zero?

Not with any sensible definition of "acceleration" and "velocity."
You CAN accelerate an object and have it end up at zero velocity. But, if the acceleration remains a non-zero number, then the velocity can NOT remain at zero.
Your question is like asking, "Can the value of a quantity change, but also remain the same?"

What is an accurate statement of an acceleration value translation from symbols into words?
Acceleration as in metres per second per second? The acceleration of a car for example? In words, acceleration is the rate of change of speed. (Speed is the rate of change of position).
Can acceleration be a negative number?
Yes, the scalar value of acceleration can be a negative number. Acceleration is the rate of change of velocity. If the speed of an object is reducing (it is slowing down), then the object is subject to a negative acceleration. An example is when you apply the brakes in a car. The brakes change the speed of the car from a higher value to a lower value, thus imposing a negative acceleration. Colloquially, people speak of deceleration, however the correct term is negative acceleration.
The speed at which an object falls and the acceleration at which it falls are always the same value.?
false.
Does acceleration have a negative or positive value if the velocity is increasing speed?
In this case, acceleration is positive. Negative acceleration would cause the object to slow down (decelerate.)
The speed at which an object falls and the acceleration at which it falls are always the same value?
No. In a vacuum, all objects fall with the same constant acceleration, meaning that their speed constantly increases. Near the surface of the earth, the speed of any falling object increases by 32.2 feet (9.8 meters) per second every second. These numbers represent the "acceleration of gravity" at the earth's surface.
What is the acceleration of car that travels in a straight line at constant speed?
Straight line at a constant speed = no acceleration
Can speed exceed acceleration?
Well, Speed is not the same thing as Acceleration. But to answer you question the best I can: the numerical value of speed can be higher than the numerical value of acceleration - for example, an object can have a speed of 10 feet per second while accelerating at 2 feet per second squared.

What is the decrease of speed called in physics?
Any change of velocity, including a decrease of speed, is described and measured as acceleration. Assuming the velocity and acceleration vectors point in the same direction, then in the case of decreasing speed, the magnitude of the acceleration is a negative value. Negative acceleration is often called deceleration, but that is just a special case of acceleration.
Does acceleration have a negative or positive value if the velocity is increasing speed?
In this case, acceleration is positive. Negative acceleration would cause the object to slow down (decelerate.)
What is a nonzero place value?
an integer
Is it possible for a body to have the same acceleration and velocity?
The velocity and acceleration can have the same numeric value, but the units will be different. ----------------------------------------------------------------------------------------- No it is not possible. Because so long there is acceleration then the velocity has to change either in magnitude or in direction or in both. So it is not at all possible for acceleration and velocity to be the same simultaneously.
How is motion demonstratd with snowboarding?
Snowboarding demonstrates speed, velocity, and acceleration. It can also demonstrate a positive or negative value for velocity and acceleration.
Is it possible for a body to have an acceleration when moving with constant speed explain?
Yes, it's acceleration will be zero because the velocity isn't changing, but it has an acceleration. Think of it in terms of integration and derivation. Acceleration is the derivative of velocity, so if velocity is a constant number the acceleration must be zero.Generally if value of acceleration is "zero", we consider it to mean that there is NO acceleration. The question that was actually answered above was "Can acceleration be DEFINED fora body moving at constant speed?"It is possible for an object to be moving at a constant angular speed and yet have an effective acceleration in a tangential direction.===========================================Both of you guys are missing the most important point here, with the resultthat you have to twist your own arm almost to the point of dislocation in orderto state an answer.The essential underlying consideration is that, contrary to popular misconception,"acceleration" does not mean 'speeding up', or even 'changing speed'. It means"change in velocity", and "velocity" means "speed anddirection". If either speedor direction change, then that means there is 'acceleration'.The answer to the question is simple, and almost entirely non-technical. It is:"Yes, because 'acceleration' means change of either speed or direction. So, ifthe direction of the body's motion is changing, then the body has acceleration,even if its speed is constant."
What is the Multiplicative Inversre property?
The multiplicative inverse property is a property such that: a(1/a) = 1 where a is nonzero value. If a is a nonzero value, then the multiplicative inverse of a is 1/a.
