Why is traveling in a circle at constant speed called acceleration?
Traveling in any direction, but moving is acceleration. if a particle moves in a circle and comes to the initial position, then the velocity would be zero. acceleration is a scalar quantity and not a vector quantity. answered by K.Sreram from India
Why is something accelerating when it is traveling in a circle?
Something is accelerating when it is traveling in a circle because the direction of its velocity is changing.It is important to understand that a velocity not only has a magnitude but it also has a direction. In general, if the magnitude and/or direction of an object's velocity is changing, we say that it is accelerating.Again, if something is traveling and only the direction that it is traveling changes, we still say it is accelerating because the direction that it is traveling is changing.This is the case when something is traveling in a circle at constant speed. If you where to represent its velocity by a vector you would find that while the magnitude of the vector does not change over time, the direction of the vector does. In fact, over a very short period of time, if you where to represent the change in direction of its velocity by a vector, you would find that that "difference vector" points directly toward the center of the circle.Again, this is all a bit confusing because when we generally use the word "accelerate" we mean that something is speeding up. However one just has to get use to the idea that when something is accelerating, it may be that only the direction of its velocity is changing and not necessarily the magnitude of its velocity.To learn more about this go to the related links below.
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.
How is it possible to be accelerating and traveling at a constant speed?
Acceleration is the change in velocity with respect to time. Velocity is the change in position with respect to time (not the change in speed with respect to time, as you have written). Both acceleration and velocity are vector quantities, which means they have both a magnitude and a direction. Speed is simply the magnitude of the velocity. (It's what's called a "scalar" quantity, which is just a number without an associated direction.) An object can have a constant speed, but its direction of motion can be changing over time, so it's velocity is changing. The resulting nonzero change in velocity per unit time is the acceleration. An object need not be moving in a circle to meet these conditions. An object that moves at constant speed, but follows any path that is not a straight line must experience an acceleration. A circular path (like a satellite's orbit) is simply one example example of this.
Can a change in velocity always indicate a change in speed?
Velocity has direction as well as magnitude. Speed only has magnitude. So the velocity of something can change without its speed changing. This is what is happening when something is going in a circle.
How when something travels in a circle its always accelerating?
When an object travels in a circle, it is constantly changing direction, which means its velocity is also changing, even if its speed remains constant. Acceleration is defined as the rate of change of velocity, and since velocity includes both speed and direction, any change in direction constitutes acceleration. This continuous change in direction toward the center of the circle is what is known as centripetal acceleration. Therefore, an object in circular motion is always accelerating due to this constant change in direction.

What is the velocity if you travel in a 10-mile circle at 14 mph and end up where you started?
This question doesn't read as if it's the velocity you are trying to calculate. Velocity is rate of change of displacement in a specified direction. The velocity is constantly changing when travelling in a circle. It's 14 mph along the tangent to the circle at the point where you are.
Does speed change with velocity?
If the velocity changes, the speed may, or may not, change. The velocity can be thought of as having two components: a speed, and a direction. It is possible to change only the direction, for example, when an object moves in a circle at a constant speed. In this case, the velocity changes, but the speed does not.
Under what circumstances can an object move in a circular path without being accelerated?
It can't. If there is a change in direction, there is a change in velocity ("velocity" includes the direction), and therefore, an acceleration.It can't. If there is a change in direction, there is a change in velocity ("velocity" includes the direction), and therefore, an acceleration.It can't.

How can you be accelerating and traveling at a constant speed?
Acceleration refers to any change in an object's velocity, which includes changes in speed or direction. It is possible to have a constant speed while still accelerating if the direction of motion changes, for example, when moving in a circle at a constant speed. So, while the speed remains the same, the change in direction constitutes acceleration.
An object traveling at a constant rate in a circular path is changing its?
velocity continuously because velocity has both magnitude and direction. In a circular path, the direction of the object's velocity is constantly changing as it moves around the circle, even though its speed (magnitude of velocity) may remain constant.
