Because its velocity is changing all the time. The speed is constant, the velocity is not.
Yes. You can travel in a circle at constant speed, but you would still be accelerating because your direction would be changing constantly.
An object traveling in a circle is accelerating because it constantly changes its direction even though the velocity may or may not change in magnitude.
When an object is traveling with constant speed in a circle
Yes, yes, correct so far. Please go on.
Yes. The simplest example is an object moving at a constant speed in a circle.
Acceleration is change in velocity. These are vectors that have magnitude and direction. Changing either magnitude (speed) or direction will have the skater be accelerating. SO, if the skater is going at a constant speed of 2m/s in a straight line, he is not accelerating. If he is at a constant speed of 2m/s traveling in a circle (you gave the word "around"), he is accelerating. Going around in circles means there is a force constantly changing your direction. Obviously that force is coming from the skaters legs.
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.

A body is being accelerated if its speed OR direction are changing.A satellite in a perfectly circular orbit around the earth ... like a TV satellite ... is moving at constant speed. But, technically, since its direction is always changing, to keep it on a circle, it's experiencing constant acceleration.
That is possible, for example, if an object moves around in a circle. In this case, the velocity changes all the time; the speed does not.
Pi is a mathematical constant because it is the same for every perfect Circle. Pi = Circumference/Diameter of any Circle. It is constant because no matter the size of the circle that ratio always comes out to Pi. Hope they helped :)
The velocity of an object moving at a constant speed but in a circular motion due to a centripetal force is constantly changing direction (because velocity is a vector with magnitude and direction), and so since the motion of an object moving in a circle is at a tangent to the circle, this object is defined as constantly accelerating towards the centre of the circle. NB: this is at a constant speed (scalar) and with a constant radius of circle of motion
Because "acceleration" is defined as any change in the speed or direction of motion,and the direction of motion of an object moving in a circle is changing constantly.
Pi is a constant because it is the ratio of the circumference to the diameter of a circle and they are always in the exact same proportion.
As long as the object is moving in a circle at a constant speed, it is undergoing uniform circular motion.
Yep. In circular motion, you are constantly accelerating towards the center of the circle, and your velocity is constantly changing, but your speed is constant.
Any object moving in a circle (as in a centrifuge, or a planet in an orbit) is accelerating. More generally, any object that moves in a curve is accelerating (such as a car moving in a curve on the road).
A force of constant magnitude whose direction is always towards the centre of the circle.
The the skater is accelerating. Acceleration is the rate at which an object changes its velocity. Velocity is a measure of speed and vector (direction). Even though the skater is traveling at a constants speed, the skater is going in a circle around the rink so the direction is changing. Therefore the velocity is changing. Therefore the skater is accelerating.
Acceleration is the time rate of change of velocity. Velocity is a vector. It has a magnitude ( speed ) and a directio. If either the speed or the direction of motion changes the object is accelerating. Example; an object moving in a circle at constant speed is accelerating because its direction is continually changing.
Because pi is a constant. It is the ratio between the circumference and diameter of any circle (assuming it is a perfect circle).
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
No. Velocity has direction and magnitude. The magnitude can be constant, but if the body is in circular motion, the direction of the movement is constantly changing, which means that the velocity is constantly changing. Changing velocity means that the body is accelerating. In this case, because the motion of the body is always changing away from a straight line to cause it to go round the circle, the acceleration acts towards the centre of the circle.
yes, as in the case of a satellite orbiting the earth; it is moving with constant speed but not constant velocity as its direction is always changing as it orbits. The net force is provided by gravity accelerating it inward and preventing into from flying away into space
