If the speed is constant in uniform circular motion, why is there acceleration?

If the speed is constant in uniform circular motion, why is there acceleration?If the speed is constant in uniform circular motion, why is there acceleration?Acceleration is defined as speeding up slowing down or changing direction, during circular things change direction



Another way to think about this is that Acceleration is change in Velocity. Because velocity (unlike speed) depends on direction. A change in direction signifies a change in velocity. Which is Acceleration.If the speed is constant in uniform circular motion, why is there acceleration?
Acceleration is measured using velocity not speed (velocity is speed with direction), so since the object is changing its direction all the time, its velocity is changing which means there is acceleration, even though the magnitude of velocity is the same but its direction is constantly changing.If the speed is constant in uniform circular motion, why is there acceleration?yes i agree with most of their answers. The speed is not only the speed but also the speed with direction, and the direction always changes . We call it acceleration centripetal ?If the speed is constant in uniform circular motion, why is there acceleration?
A constant force must be applied to the orbiting object to prevent it from traveling in a straight line. The acceleration does not change the speed of the object but rather its direction.If the speed is constant in uniform circular motion, why is there acceleration?acceleration is a change in velocity

velocity is a vector therefore it has magnitude and direction

therefore if you change direction you are changing the velocity therefore creating accelerationIf the speed is constant in uniform circular motion, why is there acceleration?
Acceleration is about ANY change in velocity, be it a change in speed OR A CHANGE IN DIRECTION.
