What does constant velocity or acceleration mean?
"Constant" means that regardless of when you measure it, the result is always the same. "Velocity" means speed and its direction. "Acceleration" means the rate at which speed is changing, and the direction in which it's changing.
How is velocity of zero different from an accerlation at zero?
Acceleration is changing velocity. Zero velocity means no motion. Zero acceleration means constant, unchanging motion.
Why is the velocity of the car traveling in a circle changing?
Because "velocity" consists of a speed and a direction. If the direction is changing, then the velocity is changing, even though the speed isn't. And here's another one for you: "Acceleration" means any change in velocity. So if the race car is going around an oval track at a constant speed, it's accelerating. ==> Because its velocity is changing. ==> Because its direction is changing. ==> All at constant speed.
When an object and acceleration is zero at some instant t in time its velocity is?
You can't derive the velocity from the acceleration. Zero acceleration simply means that the velocity (at that instant) is not changing.
When cars are changing direction they are also changing what?
They are changing velocity. Velocity is the measure of speed and direction
Why is acceleration zero with uniform velocity?
Uniform velocity means the velocity is not changing. Acceleration is defined as the rate of change of velocity. If velocity isn't changing, the rate of change is zero.
How is constant velocity different from changing velocity?
"Constant" means that it doesn't change.
When does a particle in motion have non-uniform velocity?
That simply means that its velocity is changing.

Acceleration is changing velocity. Zero velocity means no motion. Zero acceleration means constant, unchanging motion.
What type of motion is occurring when the slope of a velocity vs. time graph is zero?
It means that the velocity is constant, or not changing.
If you are traveling around a curve at a constant speed of 30 km is the veiocity change?
Yes, the velocity is changing. Velocity is a quantity composed of the speed and the direction of motion. Constant velocity means: Constant speed, in a straight line. If the direction is changing, then the velocity is changing, even if the speed is constant.
Does 0 acceleration means 0 velocity?
Not at all. Zero acceleration just means that the velocity is not changing ...the motion is in a straight line at a consgtant speed.

You can't derive the velocity from the acceleration. Zero acceleration simply means that the velocity (at that instant) is not changing.
In uniform circulation motion is the velocity constant?
No. The direction keeps changing. Constant velocity means constant speed in a straight line.
How can a vehicle at the same time have a constant speed but changing velocity?
Speed is a scalar quantity (direction does not matter) and velocity is a vector quantity) ie velocity means speed in a specific direction. If you are changing direction (turning) in a car, your speed is the same, while your velocity changes.
