What else can I help you with?
A cyclist goes around a level circular track at constant speed. Is the cyclist's acceleration zero because her speed is constant?
No. The cyclist is moving at a constant speed, but her velocity is changing. Remember that velocity is speed with a direction vector associated with it. As speed is constant, only direction is changing. But a change in direction is a change in velocity (even if speed is constant), and this requires acceleration in that direction to accomplish the change in direction. You're on the right track, but just recall that acceleration is tied to velocity and not just speed. And note that velocity can change all the time without speed changing. Acceleration must cause the change in velocity. Consider that objects in orbit around the earth move at a pretty constant speed, but accelerate toward the earth all the time. Their speed coupled with their acceleration toward earth cause them to move in an arc - which is their orbital path.
Is there an acceleration when an object traveling at constant velocity and why?
No, there is no acceleration when an object is traveling at a constant velocity. Acceleration is the rate of change of velocity, so if the velocity is constant, there is no change and therefore no acceleration.
When the velocity of a particle is constant its acceleration is also constant?
When the velocity of a particle is constant, it means there is no change in speed or direction. Therefore, its acceleration is zero because acceleration is the rate of change of velocity. If the velocity is constant, there is no change to be measured, so the acceleration is constant at zero.
If an object is moving at a constant velocity what do you know about its acceleration?
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
Can an object traveling at constant velocity have acceleration why?
An object traveling at constant velocity cannot have acceleration because acceleration is the rate of change of velocity over time. If the velocity of an object is constant, there is no change in velocity and therefore no acceleration.

For a car moving around a circular track at a constant speed the acceleration is?
constant speed=0 acceleration Acceleration is the change in speed. If the speed doesn't change(ie constant) the acceleration is zero.

What is the difference between constant speed and constant acceleration?
Constant speed means moving at a steady rate without any change in velocity, while constant acceleration means changing the velocity by the same amount in each unit of time. In other words, constant speed is uniform motion, while constant acceleration is when the velocity is changing at a constant rate.
What is the acceleration of an object that travels in a straight line at a constant speed?
The acceleration of an object moving in a straight line at a constant speed is zero. Acceleration is the rate of change of velocity, so if the speed is constant, there is no change in velocity and thus no acceleration.
Does a car accelerate when it goes around a corner at a constant speed?
yes an acceleration is a change in speed and when you go around a corner you change your speed.
Why are you accelerating when you go around a corner at a constant speed?
Acceleration is any change in velocity. It could be a change in speed or direction. Technically, even slowing down is acceleration.
When velocity is increasing can acceleration remains constant?
Acceleration is any change in velocity. Velocity is made up of a magnitude (the speed), and a direction. Velocity can change if the speed increases, if it decreases, or if the direction changes. For example, when a car goes around a curve, you feel the force of the acceleration.
Why does acceleration change when speed does not?
Acceleration is the rate of change of speed, so if speed is constant, acceleration is zero. However, if speed is constant but direction is changing (e.g. moving in a circle at constant speed), the velocity is changing, and thus there is still acceleration.
